About ICD-9-CM 881.20

881.20 is an ICD-9-CM diagnosis code for open wound of forearm, with tendon involvement. 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 S51.809A (Unspecified open wound of unspecified forearm, initial encounter) and S56.929A (Laceration of unspecified muscles, fascia and tendons at forearm level, unspecified arm, 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.
