About ICD-9-CM 33.42

33.42 is an ICD-9-CM procedure code for closure of bronchial 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 131 ICD-10-PCS codes, such as 0BQ30ZZ (Repair Right Main Bronchus, Open Approach), 0BQ30ZZ (Repair Right Main Bronchus, Open Approach) and 0BQ30ZZ (Repair Right Main Bronchus, Open 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.
