About ICD-9-CM 27.29

27.29 is an ICD-9-CM procedure code for other diagnostic procedures on oral cavity. 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 3 ICD-10-PCS codes, such as 0WJ30ZZ (Inspection of Oral Cavity and Throat, Open Approach), 0WJ33ZZ (Inspection of Oral Cavity and Throat, Percutaneous Approach) and 0WJ34ZZ (Inspection of Oral Cavity and Throat, Percutaneous Endoscopic Approach). All of these are approximate matches, so review the record to pick the right one.
