Billing, Coding, and Credentialing for Interventional Radiology-Operated Endoscopy.

A sound understanding of billing and coding is essential to start a successful interventional radiology endoscopy practice. While the codes utilized are similar to gastrointestinal and genitourinary endoscopy codes, physicians and institutional coders need to be familiar with the codes used for these types of procedures in the interventional radiology setting. The following manuscript gives a brief overview of aspects relating to credentialing, billing, and coding in interventional radiology endoscopy.

Testicular plasmacytoma misdiagnosed as orchitis.

Testicular plasmacytomas are rare, accounting for only 1.3% of all extramedullary plasmacytomas. The infrequency in which it is encountered, coupled with its non-specific clinical and sonographic presentation, makes its diagnosis a challenge. We present a case of a 70-year-old man with multiple myeloma, which was systemically responding to chemotherapy, who developed testicular swelling, erythema and pain. Ultrasound findings were concerning for infection, although urine and serum testing were unremarkable. The patient did not improve after several rounds of antibiotics prompting further evaluation. The patient underwent radical orchiectomy which revealed testicular plasmacytoma. Fluorescent in situ hybridisation (FISH) of the testicular tissue noted mutations which had not been present in the FISH analysis of bone marrow. Positron emission tomography scan later revealed new retroperitoneal plasmacytomas involving the new clone and his chemotherapy regimen needed to be adjusted for treatment.
