When coding for routine post op cataract surgery visits, you would normally use 99024 with a $ 0.00 charge.

CMS proposed a HCPCS Level II G coding system where GXXX5 (per 10 minute increment) would probably be the most accurate code to record the time involved in the post op visits.

I’m having people tell me that their clearing houses are rejecting the G code as invalid. Did CMS not institute the G code system in 2017?

If they did, what is the proper way to code it.

I would assume you code the 99024 with $ 0.00 and then add the GXXX5 code with a number of units value attached to it and also a value of $ 0.00 but am not sure that’s correct.
