Justin B Hellman, Michele C Lim, Karen Y Leung, Cameron M Blount, Glenn Yiu Department of Ophthalmology & Vision Sciences, University of California, Davis Medical Center, Sacramento, CA, USA Purpose: To determine the financial and clinical impact of conversion from International Classification of Disease, 9th revision (ICD-9) to ICD-10 coding.Design: Retrospective, database study.Materials and methods: Monthly billing and coding data from 44,564 billable patient encounters at an academic ophthalmology practice were analyzed by subspecialty in the 1-year periods before (October 1, 2014, to September 30, 2015) and after (October 1, 2015, to September 30, 2016) conversion from ICD-9 to ICD-10.Main outcomes and measures: Primary outcome measures were payments per visit, relative value units per visit, number of visits, and percentage of high-level visits; secondary measures were denials due to coding errors, charges denied due to coding errors, and percentage of unspecified codes used as a primary diagnosis code.Results: Conversion to ICD-10 did not significantly impact payments per visit ($306.56±$56.50 vs $321.43±$38.12, P=0.42), relative value units per visit (7.15±0.56 vs 7.13±0.84, P=0.95), mean volume of visits (1,887.08±375.02 vs 1,863.83±189.81, P=0.71), or percentage of high-level visits (29.7%±4.9%, 548 of 1,881 vs 30.0%±1.7%, 558 of 1,864, P=0.81). For every 100 visits, the number of coding-related denials increased from 0.98±0.60 to 1.84±0.31 (P
