Analysis of Reimbursement of Genetic Counseling Services at a Single Institution in a State Requiring Licensure.

Reimbursement for genetic counseling services was examined at a single institution. Patient encounters utilizing the 96040 CPT® code from 7/31/2009 through 7/31/2013 were reviewed. Exclusion criteria included billing records of patients seen by a physician the same day, self-pay, Medicaid, and Medicare patients. Of the 8,630 encounters with a genetic counselor, 582 encounters were eligible for review. Descriptive statistics (i.e., percentage of encounters receiving some level of reimbursement, average reimbursement rate, number of third party payors providing any level of reimbursement, and number of ICD-9 codes receiving any level of reimbursement) depicted reimbursement of the 96040 CPT® code for the encounters analyzed. Statistical analysis found a significant difference in reimbursement between third party payors that do and do not credential genetic counselors (p < .0001). There was no statistically significant difference between reimbursement rates for primary diagnostic ICD-9 codes when compared to primary diagnostic ICD-9 V codes used. Results will provide a useful baseline for local and national comparisons due to the paucity of data regarding CPT® 96040.

Allenyl azide cycloaddition chemistry. 2,3-cyclopentennelated indole synthesis through indolidene intermediates.

The thermal, photochemical, and photochemical/CuI-mediated cascade cyclizations of a range of substituted 1-(2-azidophenyl)-3-alkenylallenes are described. These reactions provide both 1,2- and 2,3-cyclopentennelated indole products in varying ratios. In most cases, high regioselectivity for the 2,3-annelated isomer can be achieved under the hnu/CuI conditions. Computational studies of this multistep reaction support the intermediacy of indolidene intermediates whose electrocyclizations (with or without copper present) define the regioselectivity branch point in the sequence.
