Unsp inj extn musc/fasc/tend r mid fngr at wrs/hnd lv, subs

This code signifies an unspecified injury to the extensor muscle, fascia, or tendon of the right middle finger, occurring at the wrist or hand level. The "subsequent encounter" designation indicates this code is used for follow-up care after the initial treatment of the injury.

This code is appropriate for documenting follow-up visits, cast changes, physical therapy, or medication management for an injury to the right middle finger's extensor structures where the specific nature of the injury (e.g., strain, tear) was not documented or is unknown. It applies when the patient is receiving active treatment for the injury beyond the initial encounter.

• Ensure the documentation clearly states "right middle finger" and "extensor" involvement.
• Confirm the encounter is for follow-up care, not the initial treatment.
• If the specific type of injury (e.g., laceration, rupture) is known, a more specific code should be used.
