Abstract
Purpose
To provide a comparative analysis of rates of laser trabeculoplasty (LTP) among eye care providers in the USA.
Methods
This retrospective cohort analysis utilized the Centers for Medicare and Medicaid Services (CMS) Public Use File (PUF), 2015-2018. We used CPT code 65855 to select eye care providers who performed LTP in three key US states (KY, LA, and OK). Primary outcomes were eye provider differences in provider count, service count, unique beneficiary count, and Medicare-allowed payments. Asymptotic two-sided chi-squared tests were executed. Statistical significance was achieved at p<0.05.
Results
The sum of Medicare-allowed payments for LTP in all three states in 2018 was roughly 26% lower than in 2015. The proportion of Medicare-allowed payments furnished by optometrists increased from 11.3% to 17.9% between 2015 and 2018 (p<0.001). Relative to ophthalmologists, we observed significant increases in optometric Medicare-allowed payments in KY, LA, OK, and the all-inclusive tri-state cohort (all p<0.001). Furthermore, significant optometric increases in number of providers performing LTP (p=0.007), number of unique Medicare beneficiaries seen (p<0.001), and number of LTP services billed (p<0.001) were observed relative to ophthalmologists.
Conclusion
The recent expansion of surgical authority by optometrists in key US states is creating a tangible impact on ophthalmologic and optometric practice patterns. The findings of this study may act as provision for policymakers in the context of continually evolving guidelines for optometric surgical expansion.
