About ICD-9-CM 28.91

28.91 is an ICD-9-CM procedure code for removal of foreign body from tonsil and adenoid by incision. 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 8 ICD-10-PCS codes, such as 0CCP0ZZ (Extirpation of Matter from Tonsils, Open Approach), 0CCP0ZZ (Extirpation of Matter from Tonsils, Open Approach) and 0CCP3ZZ (Extirpation of Matter from Tonsils, Percutaneous 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.
