Searched 'Medicare 11750' and got the link above. Confirms that's been in place since 6/2022.
Per the article:
CPT codes 11730 and 11732 for nail avulsion will be denied if billed for the same finger less than 4 months (16 weeks) or the same toe less than 8 months (32 weeks) following a previous avulsion.
CPT code 11750 for nail excision permanent removal will be denied if billed for the same finger or toe following a previous excision.
This part's vague, but read as "lifetime"
A medically reasonable and necessary repeat avulsion or excision of the same nail within 32 weeks of a previous avulsion, or excision, of the same nail, will be considered upon redetermination. The medical record must support the service, for example, there is an ingrown nail of the opposite border or a new significant pathology on the same border recently treated.
