Trends of medicare reimbursement for breast cancer and reconstructive surgery.

This study evaluated trends in Medicare reimbursement for commonly performed breast oncologic and reconstructive procedures. Average national relative value units (RVUs) for physician-based work, facilities, and malpractice were collected along with the corresponding conversion factors for each year. From 2010 to 2021, there was an overall average decrease of 15% in Medicare reimbursement for both breast oncology (-11%) and reconstructive procedures (-16%). Based on these findings, breast and reconstructive surgeons should advocate for reimbursement that better reflects the costs of their practice.

Trends of Medicare Reimbursement Rates for Lower Extremity Procedures.

BACKGROUND: Data collected across many surgical specialties suggest that Medicare reimbursement for physicians consistently lags inflation. Studies are needed that describe reimbursement rates for lower extremity procedures. Our goal is to analyze the trends in Medicare reimbursement rates from 2010 to 2021 for both lower extremity amputation and salvage surgeries. METHODS: The Physician Fee Schedule Look-Up Tool of the Centers for Medicare and Medicaid Services was assessed and Current Procedural Terminology codes for common lower extremity procedures were collected. Average reimbursement rates from 2010 to 2021 were analyzed and adjusted for inflation. The rates of work-, facility-, and malpractice-related relative value units (RVUs) were also collected. RESULTS: We found an overall increase in Medicare reimbursement of 4.73% over the study period for lower extremity surgery. However, after adjusting for inflation, the average reimbursement decreased by 13.19%. The adjusted relative difference was calculated to be (-)18.31 and (-)11.34% for lower extremity amputation and salvage procedures, respectively. We also found that physician work-related RVUs decreased by 0.27%, while facility-related and malpractice-related RVUs increased. CONCLUSION: Reimbursement for lower extremity amputation and salvage procedures has steadily declined from 2010 to 2021 after adjusting for inflation, with amputation procedures being devaluated at a greater rate than lower extremity salvage procedures. With the recent marked inflation, knowledge of these trends is crucial for surgeons, hospitals, and health care policymakers to ensure appropriate physician reimbursement. LEVEL OF EVIDENCE: IV (cross-sectional study).

United States insurance coverage of immediate lymphatic reconstruction.

INTRODUCTION: Immediate Lymphatic Reconstruction (ILR) is a prophylactic microsurgical lymphovenous bypass technique developed to prevent breast cancer related lymphedema (BCRL). We investigated current coverage policies for ILR among the top insurance providers in the United States and compared it to our institutional experience with obtaining coverage for ILR. METHODS: The study analyzed the publicly available ILR coverage statements for American insurers with the largest market share and enrollment per state to assess coverage status. Institutional ILR coverage was retrospectively analyzed using deidentified claims data and categorizing denials based on payer reason codes. RESULTS: Of the 63 insurance companies queried, 42.9% did not have any publicly available policies regarding ILR coverage. Of the companies with a public policy, 75.0% deny coverage for ILR. In our institutional experience, $170,071.80 was charged for ILR and $166 118.99 (97.7%) was denied by insurance. CONCLUSIONS: Over half of America's major insurance providers currently deny coverage for ILR, which is consistent with our institutional experience. Randomized trials to evaluate the efficacy of ILR are underway and focus should be shifted towards sharing high level evidence to increase insurance coverage for BCRL prevention.

Clinical Outcomes Following Resection of Distal Lower Extremity Soft Tissue Sarcomas.

OBJECTIVE: Resection of soft tissue sarcoma (STS) in the distal lower extremity can result in large soft tissue defects that create difficult wounds to manage and significant risks for complications. Often, the anticipated or resultant tissue defect or loss of functional anatomy is an indication for amputation over limb salvage. Soft tissue reconstruction managed by plastic and reconstructive surgery (PRS) may help offer limb salvage as a therapeutic option with acceptable oncologic outcomes and wound complication rates. METHODS: This was a review of 52 patients who underwent resection of STS at the level of the knee or distal between 2010 and 2020. Plastic and reconstructive surgery soft tissue management was utilized in 40.4% (n = 21) of cases, most of whom would have otherwise been considered candidates for amputation. RESULTS: The overall rate of limb salvage was 76.9%. The overall rate of wound complications was 19.2%. The overall rate of negative margins of resection was 92.3%. The 1-, 5-, and 10-year overall survival probabilities were 92%, 85%, and 85%, respectively. Of the 40 limb salvage procedures, two required subsequent amputation, one for multiply recurrent disease and one for necrosis. The wound complication rate was 14.3% in the PRS management group and 22.6% in cases of wound closure managed by the primary surgeon. There were zero instances of total wound or flap loss in PRS- managed closures. When comparing patients with wound complications to those without, there was no difference in age (59.5 ± 21 vs. 51 ± 18 years, p = 0.42), body mass index (31.1 ± 4.8 vs. 26.1 ± 7.1 kg/m2 , p = 0.19), or tumor size (6.8 ± 5.0 vs. 6.4 ± 4.7 cm, p = 0.82). At final follow-up, 67% (n = 35) of patients were alive and disease-free. CONCLUSIONS: Wound complications are not uncommon after resection of distal lower extremity STS. Our experience has been successful in achieving limb salvage in these challenging cases. Without PRS soft tissue management, however, many patients may alternatively be candidates for amputation.

Pressure injuries in COVID-19 patients: A tertiary center experience.

Pressure ulcers continue to severely impact patient outcomes and increase health care costs. We aimed to examine the incidence and risk factors related to pressure ulcers among COVID-19 patients. A retrospective was conducted between March 2020-April 2021. Baseline differences were examined using chi-square and Fischer's exact test. Logistic regression was employed to examine the association of the collected variables to development of new pressure ulcers. 4608 patients were included, of which eighty-three acquired new pressure ulcers. Risk factors were increased age, peripheral artery disease, abnormal albumin levels, but not prone position.

Safety and Efficacy of Extended Postdischarge Venous Thromboembolism Prophylaxis in Microsurgical Breast Reconstruction.

Discharging patients on extended postoperative venous thromboembolism (VTE) prophylaxis is trending in microsurgical breast reconstruction (MBR). This study investigated contemporary bleeding and thromboembolic complications after MBR and reported postdischarge enoxaparin outcomes. Methods: The PearlDiver database was queried for MBR patients who did not receive postdischarge VTE prophylaxis (cohort 1) and MBR patients discharged with enoxaparin for at least 14 days (cohort 2), then queried for hematoma, deep venous thrombosis (DVT), and/or pulmonary embolism. Concurrently, a systematic review was undertaken to identify studies investigating VTE with postoperative chemoprophylaxis. Results: In total, 13,541 patients in cohort 1 and 786 patients in cohort 2 were identified. The incidence of hematoma, DVT, and pulmonary embolism were 3.51%, 1.01%, 0.55% in cohort 1, and 3.31%, 2.93%, and 1.78% in cohort 2, respectively. There was no significant difference in hematoma between these two cohorts (P = 0.767); however, a significantly lower rate of DVT (P < 0.001) and pulmonary embolism (P < 0.001) occurred in cohort 1. Ten studies met systematic review inclusion. Only three studies reported significantly lower VTE rates with postoperative chemoprophylaxis. Seven studies found no difference in bleeding risk. Conclusions: This is the first study utilizing a national database and a systematic review to investigate extended postoperative enoxaparin in MBR. Overall, rates of DVT/PE seem to be declining compared with previous literature. The results of this study suggest that there remains a lack of evidence supporting extended postoperative chemoprophylaxis, although the therapy appears safe in that it does not increase bleeding risk.

Burden of Pressure Injuries: Findings From the Global Burden of Disease Study.

Background: Pressure injuries remain among the most common problems faced by plastic surgeons and comprise a large portion of wound clinic practice. However, little is known about the overall morbidity related to the disease. This research sought to identify the burden related to the diagnosis of pressure injuries. Methods: We used the Global Burden of Disease Study 2017 to extract information about incidence and disability-adjusted life years (DALYs) related to pressure injuries from 1990 to 2017. Descriptive statistics were used to identify changes in the outcomes of interest. Results: A relative though not statistically significantly decrease in the incidence and burden of pressure injuries was observed between 1990 and 2017. Rates of incidence in the US appear higher than other higher socio-demographic index countries. No clinically and statistically significant changes were observed based on age or sex. Conclusions: Pressure injury incidence and burden have remained relatively stable between 1990 and 2017 with no significant improvement noted. There is room for improvement on a national performance level, and further research is needed regarding inconsistencies in regional outcomes.

Trends in Skin Melanoma Burden: Findings From the Global Burden of Disease Study.

Background: Melanoma is the third most common skin cancer and the leading cause of skin cancer mortality. This study sought to investigate trends in melanoma incidence, mortality, and burden of disease. Methods: The authors assessed the records of the Global Burden of Disease Study 2017 to extract information about the incidence, mortality, and disability adjusted life years (DALY) related to melanoma during 1990-2017 in the US and other countries based on their socio-demographic index (SDI). Results: Melanoma incidence in the US increased 1.6 times, although the difference was not statistically significant. For patients over the age of 60, the incidence was significantly increased by 1.72 to 164.6 times. Mortality was relatively stable during the study period; however, it was increased for patients over 65 years of age (range: 1.03 to 70 times), although not statistically significant. Mortality-to-incidence ratio was decreased, but the difference was not statistically significant. For patients over 75 years of age, DALYs were statistically significantly increased by 1.34 to 1.71 times. Conclusions: This study highlights differences in melanoma incidence and mortality from 1990-2017. Physicians involved in melanoma care should be aware of these changes in order to anticipate care needs.

Trends of Medicare Reimbursement Rates for Common Plastic Surgery Procedures.

BACKGROUND: Knowledge of Medicare reimbursement is essential for plastic surgeons providing care to Medicare beneficiaries. The authors sought to evaluate changes in Medicare reimbursement for common plastic surgery procedures from 2010 to 2020. METHODS: The authors assessed the Physician Fee Schedule of the Centers for Medicare and Medicaid Services website. Rates of work-, facility-, or malpractice-related relative value units and total monetary units for 26 common plastic surgery procedures between 2010 and 2020 were evaluated. Descriptive statistics were used to calculate relative differences and to compare observed changes over time with the rate of inflation. RESULTS: For the selected procedures, the authors found an average relative difference in terms of monetary units of an increase by 2.02 percent. However, after adjusting for inflation, the average relative difference was a decrease by 14.31 percent. The authors' analysis indicates that, on average, there was a 1.55 percent decrease in physician relative value units between 2010 and 2020. CONCLUSIONS: Medicare reimbursement rates have changed significantly over the past decade. However, these changes did not keep pace with the rate of inflation. Plastic surgeons should be aware of these trends and advocate for more fair reimbursement rates.

The Affordable Care Act and Its Impact on Plastic and Gender-Affirmation Surgery.

SUMMARY: The Affordable Care Act's provisions have affected and will continue to affect plastic surgeons and their patients, and an understanding of its influence on the current American health care system is essential. The law's impact on pediatric plastic surgery, craniofacial surgery, and breast reconstruction is well documented. In addition, gender-affirmation surgery has seen exponential growth, largely because of expanded insurance coverage through the protections afforded to transgender individuals by the Affordable Care Act. As gender-affirming surgery continues to grow, plastic surgeons have the opportunity to adapt and diversify their practices.

Urban Frostbite: Strategies for Limb Salvage.

Under ideal circumstances, severely frostbitten extremities are rapidly rewarmed and treated with thrombolytic therapy within 6 to 24 hours. In an "inner city," urban environment, most patients who suffer frostbite injuries present in a delayed fashion, sustain repeated injuries further complicated by psychological issues or intoxication, and are rarely ideal candidates for thrombolytic therapy within the prescribed timeframe. We describe our experience with the treatment of urban frostbite injuries. A retrospective review of patients with cold injuries sustained between November 2013 and March 2014 treated at a verified burn center in an urban setting was performed. Fifty-three patients were treated (42 males, 11 females). Average patient age was 41.8 years (range 2-84 years). No patients met criteria for thrombolytic therapy due to multiple freeze-thaw cycles or presentation greater than 24 hours after rewarming. Deep frostbite was seen in 10 patients. Of these patients, nine underwent debridement, resulting in partial limb amputations at levels guided by Tri-phasic technetium (Tc-99m) bone scans. Wound closure and limb-length salvage was then achieved by: free flap coverage (n = 2), local flaps (n = 8), split-thickness skin grafting (n = 22), and secondary intention healing (n = 6). While tissue plasminogen activator has been successful in reducing the need for digital amputation following frostbite injuries, in our experience, this treatment modality is not applicable to the urban patient population who often present late and after cycles of reinjury. Therefore, our approach focused on salvaging limb length with durable coverage, as the injuries were unable to be reversed.

Immediate Dental Implantation in Oncologic Jaw Reconstruction: Workflow Optimization to Decrease Time to Full Dental Rehabilitation.

Full dental rehabilitation following segmental mandibulectomy or maxillectomy for oncologic tumor ablation should be the goal for every patient. But despite advances in technology and reconstructive techniques, many patients do not achieve timely or complete oral rehabilitation. Recognizing this fault, we recently adopted an innovative workflow to increase the number of patients undergoing dental restoration, irrespective of tumor pathology or need for adjuvant radiotherapy. Preoperatively, every osseous jaw reconstruction undergoes virtual surgical planning to incorporate the placement of endosseous implants into the fibula osteocutaneous free flap. The dental implants are then placed intraoperatively at the time of tumor ablation and reconstruction. Four-to-six weeks following the initial surgery, the patient returns to the operating room for vestibuloplasty and exposure of the dental implants. Within 3 days of the vestibuloplasty, a temporary dental prosthesis is placed in the dental clinic, and the patient can then begin radiation therapy if needed. Following adjuvant radiation therapy, the temporary prosthesis can be replaced with a permanent one. At our institution, this innovative workflow has allowed for earlier aesthetic restoration of the jaw and greatly expanded the number of patients able to achieve oral rehabilitation. Herein, we describe this innovative workflow and provide technical pearls for successful execution.

Virtual planning and navigational technology in reconstructive surgery.

Reconstructive technologies have expanded to include the use of virtual surgical planning (VSP) and computer-aided design and manufacturing (CAD-CAM), and 3-Dimensional printing. The advantages of VSP over traditional techniques are highlighted in many scenarios: (a) delayed reconstruction, (b) maxillary reconstruction, (c) placement of dental implants, and (d) precision guided oncology. Microsurgery is undergoing a paradigm shift with virtual planning at its foreground. Herein, we describe the versatile uses for CAD-CAM and key operative steps.

SSET Project: Cost-effectiveness Analysis of Surgical Specialty Emergency Trays in the Emergency Department.

BACKGROUND: We hypothesize that reusable, on-site specialty instrument trays available to plastic surgery residents in the emergency department (ED) for bedside procedures are more cost-effective than disposable on-site and remote re-usable operating room (OR) instruments at our institution. METHODS: We completed a cost-effectiveness analysis comparing the use of disposable on-site kits and remote OR trays to a hypothetical, custom, reusable tray for ED procedures completed by PRS residents. Material costs of existing OR trays were used to estimate the purchasing and use-cost of a custom on-site tray for the same procedures. Cost of per procedure 'consult time' was estimated using procedure and resident salary. RESULTS: Sixteen bedside procedures were completed over a 4.5 month period. A mean of 2.14 disposable kits were used per-procedure. Mean consultation time was 1.66 hours. Procedures that used OR trays took 3 times as long as procedures that used on-site kits (4 vs. 1.1 hours). Necessary, additional instruments were unavailable for 75% of procedures. Mean cost of using disposable kits and OR trays was $115.03/procedure versus an estimated $26.67/procedure cost of using a custom tray, yielding $88.36/procedure cost-savings. Purchase of a single custom tray ($1,421.55) would be redeemed after 2.3 weeks at 1 procedure/day. Purchasing 4 trays has projected annual cost-savings of $26,565.20. CONCLUSION: The purchase of specialized procedure trays will yield valuable time and cost-savings while providing quality patient care. Improving time efficiency will help achieve the Accreditation Council of Graduate Medical Education (ACGME) goals of maintaining resident well-being and developing quality improvement competency.

Cold Injuries.

New treatments of frostbite have led to unprecedented salvage of extremities including fingers and toes. Success is predicated on prompt institution of time-sensitive protocols initiated soon after rewarming, particularly the use of thombolytics. Unfortunately, in the urban setting, most patients are not candidates for these treatment modalities. Triple-phase bone scans have allowed for early determination of devitalized parts that need amputation. Reconstructive surgical techniques are typically used to salvage limb length in these devastating injuries.

Breast Reconstruction with SIEA Flaps: A Single-Institution Experience with 145 Free Flaps.

BACKGROUND: Refinements in microsurgical breast reconstruction have refined superficial inferior epigastric artery (SIEA) and superficial circumflex iliac artery (SCIA) flaps, yet technical difficulties and varied success rates limit widespread acceptance. The authors present the outcomes of their experience with 145 consecutive SIEA/SCIA flaps and suggest technical tips to improve success with this important flap. METHODS: An institutional review board-approved retrospective chart review of all SIEA/SCIA free flaps performed by the senior authors between January 1, 2006, and February 6, 2014, was conducted. Data on patient demographics, flap characteristics, and complications were collected. RESULTS: There were 145 flaps performed in 119 patients. Arterial donor and recipient mismatch occurred in 55 instances (38 percent). In these cases, 48 arteries (87 percent) were spatulated and seven (13 percent) were back-cut to improve size concordance. Nine flaps required operative return for flap viability concerns. Five were arterial, three were venous, and one flap had concomitant arterial and venous thrombosis. Total flap loss rate attributable to thrombotic events was 4.8 percent. No flaps with arterial thrombosis on reoperation were salvageable. Furthermore, 80 percent had arterial revisions at initial operation. No patients had an abdominal bulge or hernia, and the fat necrosis rate was 10.3 percent. CONCLUSIONS: SIEA/SCIA breast reconstruction can be reliably performed; however, flaps exhibiting postoperative arterial thrombosis with revision at initial surgery are unlikely salvageable on reoperation. Spatulation did not correlate with an increased thrombosis rate; in fact, the authors advocate for donor artery manipulation to manage size mismatch. CLINCAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Characterization of Reversibly Immortalized Calvarial Mesenchymal Progenitor Cells.

BACKGROUND: Bone morphogenetic proteins (BMPs) play a sentinel role in osteoblastic differentiation, and their implementation into clinical practice can revolutionize cranial reconstruction. Preliminary data suggest a therapeutic role of adenoviral gene delivery of BMPs in murine calvarial defect healing. Poor transgene expression inherent in direct adenoviral therapy prompted investigation of cell-based strategies. OBJECTIVE: To isolate and immortalize calvarial cells as a potential progenitor source for osseous tissue engineering. MATERIALS AND METHODS: Cells were isolated from murine skulls, cultured, and transduced with a retroviral vector bearing the loxP-flanked SV40 large T antigen. Immortalized calvarial cells (iCALs) were evaluated via light microscopy, immunohistochemistry, and flow cytometry to determine whether the immortalization process altered cell morphology or progenitor cell profile. Immortalized calvarial cells were then infected with adenoviral vectors encoding BMP-2 or GFP and assessed for early and late stages of osteogenic differentiation. RESULTS: Immortalization of calvarial cells did not alter cell morphology as demonstrated by phase contrast microscopy. Mesenchymal progenitor cell markers CD166, CD73, CD44, and CD105 were detected at varying levels in both primary cells and iCALs. Significant elevations in alkaline phosphatase activity, osteocalcin mRNA transcription, and matrix mineralization were detected in BMP-2 treated iCALs compared with GFP-treated cells. Gross and histological analyses revealed ectopic bone production from treated cells compared with controls in an in vivo stem cell implantation assay. CONCLUSION: We have established an immortalized osteoprogenitor cell line from juvenile calvarial cells that retain a progenitor cell phenotype and can successfully undergo osteogenic differentiation upon BMP-2 stimulation. These cells provide a valuable platform to investigate the molecular mechanisms underlying intramembranous bone formation and to screen for factors/small molecules that can facilitate the healing of osseous defects in the craniofacial skeleton.

Postoperative Pain and Length of Stay Lowered by Use of Exparel in Immediate, Implant-Based Breast Reconstruction.

BACKGROUND: Patients undergoing mastectomy and prosthetic breast reconstruction have significant acute postsurgical pain, routinely mandating inpatient hospitalization. Liposomal bupivacaine (LB) (Exparel; Pacira Pharmaceuticals, Inc., Parsippany, N.J.) has been shown to be a safe and effective pain reliever in the immediate postoperative period and may be advantageous for use in mastectomy and breast reconstruction patients. METHODS: Retrospective review of 90 immediate implant-based breast reconstruction patient charts was completed. Patients were separated into 3 groups of 30 consecutively treated patients who received 1 of 3 pain treatment modalities: intravenous/oral narcotic pain control (control), bupivacaine pain pump, or LB injection. Length of hospital stay, patient-reported Visual Analog Scale (VAS) pain scores, postoperative patient-controlled analgesia usage, and nausea-related medication use were abstracted and subjected to analysis of variance and multiple linear-regression analysis, as appropriate. RESULTS: Subjects were well-matched for age (P = 0.24) regardless of pain-control modality. Roughly half (53%) of control and pain pump-treated subjects had bilateral procedures, as opposed to 80% of LB subjects. Mean length of stay for LB subjects was significantly less than control (1.5 days vs 2.00 days; P = 0.016). LB subjects reported significantly lower VAS pain scores at 4, 8, 12, 16, and 24 hours compared with pain pump and control (P < 0.01). There were no adverse events in the LB group. CONCLUSION: Use of LB in this group of immediate breast reconstruction patients was associated with decreased patient VAS pain scores in the immediate postoperative period compared with bupivacaine pain pump and intravenous/oral narcotic pain management and reduced inpatient length of stay.

Bone morphogenetic protein-9 effectively induces osteogenic differentiation of reversibly immortalized calvarial mesenchymal progenitor cells.

Critical-sized craniofacial defect repair represents a significant challenge to reconstructive surgeons. Many strategies have been employed in an effort to achieve both a functionally and cosmetically acceptable outcome. Bone morphogenetic proteins (BMPs) provide a robust osteoinductive cue to stimulate bony growth and remodeling. Previous studies have suggested that the BMP-9 isoform is particularly effective in promoting osteogenic differentiation of mesenchymal progenitor cells. The aim of this study is to characterize the osteogenic capacity of BMP-9 on calvarial mesenchymal progenitor cell differentiation. Reversibly immortalized murine calvarial progenitor cells (iCALs) were infected with adenoviral vectors encoding BMP-9 or GFP and assessed for early and late stages of osteogenic differentiation in vitro and for osteogenic differentiation via in vivo stem cell implantation studies. Significant elevations in alkaline phosphatase (ALP) activity, osteocalcin (OCN) mRNA transcription, osteopontin (OPN) protein expression, and matrix mineralization were detected in BMP-treated cells compared to control. Specifically, ALP activity was elevated on days 3, 7, 9, 11, and 13 post-infection and OCN mRNA expression was elevated on days 8, 10, and 14 in treated cells. Additionally, treatment groups demonstrated increased OPN protein expression on day 10 and matrix mineralization on day 14 post-infection relative to control groups. BMP-9 also facilitated the formation of new bone in vivo as detailed by gross, microcomputed tomography, and histological analyses. Therefore, we concluded that BMP-9 significantly stimulates osteogenic differentiation in iCALs, and should be considered an effective agent for calvarial tissue regeneration.
