About ICD-9-CM 903.9
903.9 is an ICD-9-CM diagnosis code for injury to unspecified blood vessel of upper extremity. 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 S45.909A (Unspecified injury of unspecified blood vessel at shoulder and upper arm level, unspecified arm, initial encounter), S55.909A (Unspecified injury of unspecified blood vessel at forearm level, unspecified arm, initial encounter) and S65.909A (Unspecified injury of unspecified blood vessel at wrist and hand level of unspecified arm, initial encounter). All of these are approximate matches, so review the record to pick the right one.
