About ICD-9-CM 22.2
22.2 is an ICD-9-CM procedure code for intranasal antrotomy. 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 6 ICD-10-PCS codes, such as 09CQ3ZZ (Extirpation of Matter from Right Maxillary Sinus, Percutaneous Approach), 09CQ4ZZ (Extirpation of Matter from Right Maxillary Sinus, Percutaneous Endoscopic Approach) and 09CQ8ZZ (Extirpation of Matter from Right Maxillary Sinus, Via Natural or Artificial Opening Endoscopic). All of these are approximate matches, so review the record to pick the right one.
