Lacerat extn musc/fasc/tend r idx fngr at wrs/hnd lv, init

This code signifies a tear or cut to the extensor muscle, its surrounding fascia, or the tendon of the right index finger. The injury is specifically located at the wrist or hand level, indicating damage to the structures responsible for extending the index finger.

Apply this code for acute traumatic lacerations of the right index finger's extensor mechanism, such as those resulting from a sharp object. This includes injuries diagnosed during the initial treatment phase, prior to definitive surgical repair or extensive follow-up care.

• Ensure documentation specifies "right index finger" and "extensor" to differentiate from other digits or flexor injuries.
• Confirm the injury is a laceration (cut/tear) and not a strain, sprain, or rupture without an open wound.
• The "A" suffix indicates an initial encounter, meaning the patient is receiving active treatment for the injury.
