About ICD-9-CM 838.16

838.16 is an ICD-9-CM diagnosis code for open dislocation of interphalangeal (joint), foot. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-CM took over.

The CMS General Equivalence Mappings translate it to 2 ICD-10-CM codes, such as S91.109A (Unspecified open wound of unspecified toe(s) without damage to nail, initial encounter) and S93.119A (Dislocation of interphalangeal joint of unspecified toe(s), initial encounter). 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.
