In this blog, I do my annual analysis of Category III or "T" codes. CMS lists 260 active Cat III codes for CY2021. Total payments for 2021 were $185M, but highly concentrated.
Only the top 30 had more than $100K in utilization. Only codes in the top 75 had more than $10,000 in utilization. Just about half had $1000 or less in utilization, many of those being "0".
The top 11 codes had more than $1M in payments, of which 5 or about half were related to ophthalmology. The top code, 0191T, an anterior segment ocular procedure, had $122M in payments or 66% of all payments for all of the 260 Category III codes.
The top 4 codes had 85% of payments, for the 260 codes. As to pricing per use, about half of the top 11 codes paid more than $1000 per use.

0055T (the bottom code) is a bizarrely over-aged Cat III code and somehow remained Cat III even with years of use and >8000 uses per year (in Medicare). For CY2023, the oldest codes are 0042T and 0054T, 0055T.
