About ICD-9-CM 891.1

891.1 is an ICD-9-CM diagnosis code for open wound of knee, leg [except thigh], and ankle, complicated. 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 3 ICD-10-CM codes, such as S81.029A (Laceration with foreign body, unspecified knee, initial encounter), S81.829A (Laceration with foreign body, unspecified lower leg, initial encounter) and S91.029A (Laceration with foreign body, unspecified ankle, initial encounter). All of these are approximate matches, so review the record to pick the right one.
