About ICD-9-CM 29.52

29.52 is an ICD-9-CM procedure code for closure of branchial cleft fistula. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-PCS took over.

The CMS General Equivalence Mappings translate it to 21 ICD-10-PCS codes, such as 09Q30ZZ (Repair Right External Auditory Canal, Open Approach), 09Q33ZZ (Repair Right External Auditory Canal, Percutaneous Approach) and 09Q34ZZ (Repair Right External Auditory Canal, Percutaneous Endoscopic Approach). All of these are approximate matches, so review the record to pick the right one. Some mappings are combinations: more than one ICD-10 code is needed to fully express the ICD-9 code.
