Correlation Between Relative Value Units and Operative Time for Peripheral Nerve Surgeries

The work relative value unit (wRVU) system quantifies surgeons' effort and resources for procedures. Studies have shown its inaccuracy in capturing the complexity of certain plastic and upper extremity surgeries. Analysis for peripheral nerve surgery (PNS), a growing niche within hand and plastic surgery, has not been performed. The authors aim to evaluate the PNS wRVUs by correlation to their operative time.

A retrospective analysis with current procedure terminology (CPT) codes for PNS (2005-2021) from the American College of Surgeons National Surgical Quality Improvement Program database was performed. Efficiency was determined by wRVU per operative time. Correlation was performed between operative time with wRVU and wRVU/minute.

A total of 2402 procedures across 21 CPT Codes were included and categorized into neuroplasty, nerve repair, and nerve grafting/transfers with the median operative time being 63.75, 100, and 153.78 minutes respectively. Nerve graft/transfer generated the maximum wRVU (mean 16.35). Neuroplasty generated the minimum wRVU (mean 7.24). Nerve grafts/transfers generated the least wRVUs per minute (0.09). Longer operative times were associated with higher wRVUs. Neuroplasty (R = .86) and nerve repairs (R = .84) had a strong correlation to the operative time. Nerve grafts/transfer had a positive but moderate correlation with the operative time (R = .67). All procedures had a negative correlation between operative time and wRVU/minute.

Nerve grafts/transfers had reduced compensation compared to neuroplasty or nerve repairs. Compensation did not reflect the procedure efficiency. This disparity in wRVU allocation for complex PNS underscores the need for remuneration reform.
