ICD-10-CMOther injury of intrinsic muscle, fascia and tendon of right index finger at wrist and hand level, initial encounter
This code signifies an injury to any of the small muscles, their surrounding connective tissue, or their tendons located within the right index finger, specifically at the wrist or hand level. This injury is not further specified as a strain, laceration, or rupture, but rather falls into a "catch-all" category for other types of damage. It indicates the initial treatment or encounter for this particular injury.
Use this code when documentation describes an injury to an intrinsic muscle, fascia, or tendon of the right index finger at the wrist or hand level, and the specific type of injury (e.g., strain, laceration, rupture) is not documented or does not fit other more specific codes. This applies to the initial visit for evaluation and treatment of such an injury.
