Discrepancies in Work Relative Value Unit Assignment Based on Operative Time in Hand Surgery.

Area of Science:

• Orthopedics
• Health Economics
• Surgical Outcomes

Background:

• Work relative value units (wRVUs) are a key factor in US physician reimbursement.
• The alignment of wRVUs with operative time in hand surgery requires evaluation.

Purpose of the Study:

• To determine if wRVUs accurately reflect the operative time invested in hand surgery procedures.
• To identify potential discrepancies in reimbursement based on procedure duration.

Main Methods:

• Analysis of 46,800 cases from the 2013-2018 National Surgical Quality Improvement Program database.
• Inclusion of the 50 most common single Current Procedural Terminology (CPT) code hand surgery procedures.
• Linear regression analysis to assess the relationship between operative time, wRVUs, and wRVUs per hour.

Main Results:

• A moderate positive linear correlation (R² = 0.60) was found between operative time and wRVUs in hand surgery.
• Each additional hour of operative time correlated with an increase of 6.3 wRVUs (P < .001).
• Significant deviations from expected wRVUs (59.7% to 172.6%) were observed, with shorter procedures (<1 hour) yielding higher wRVUs per hour.

Conclusions:

• A notable positive correlation exists between wRVUs and operative time in hand surgery.
• Outliers in the data suggest that current wRVU structures may not fully account for operative time, leading to reimbursement inconsistencies.
