Unsp inj extn musc/fasc/tend l rng fngr at wrs/hnd lv, subs

This code signifies an unspecified injury to the extensor muscle, fascia, or tendon of the left ring finger. The injury is located at the wrist or hand level, indicating involvement of the structures responsible for extending the finger. This code is specifically for encounters following the initial treatment of the injury.

Use this code for follow-up visits, rehabilitation, or subsequent evaluations of an unspecified extensor injury to the left ring finger. This applies when the exact nature of the injury (e.g., strain, tear) was not specified at the initial encounter or is still undetermined. It is appropriate for patients receiving ongoing care for this particular injury.

• Ensure the documentation clearly states "left ring finger" and "extensor" involvement at the "wrist and hand level."
• Confirm this is a subsequent encounter, not the initial treatment, as indicated by the 7th character 'D'.
• If the specific type of extensor injury (e.g., laceration, rupture) is later identified, a more specific code should be used.
