About coding thumb injury
The ICD-10-CM code for thumb injury is S69.9 (Unspecified injury of wrist, hand and finger(s)). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on S69.9.
Within S69, choose S69.9 (Unspecified injury of wrist, hand and finger(s)) only when documentation doesn't support a more specific option: other specified injuries of wrist, hand and finger(s) (S69.8).
Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.
