Unsp inj intrns musc/fasc/tend r lit fngr at wrs/hnd lv,subs

This code indicates an unspecified injury to the intrinsic muscles, fascia, or tendons of the right little finger at the wrist or hand level, documented during a subsequent encounter. This means the patient is receiving follow-up care for an injury that was previously diagnosed and treated.

Use this code for follow-up visits, cast changes, or medication refills related to an initial injury of the intrinsic structures of the right little finger. This applies when the specific nature of the muscle, fascia, or tendon injury was not or could not be precisely identified at the time of the initial diagnosis.

• Ensure documentation clearly states "subsequent encounter" or indicates ongoing treatment for a previously diagnosed injury.
• Verify the injury location is specifically the right little finger at the wrist or hand level.
• If the specific intrinsic muscle, fascia, or tendon is identified, a more specific code should be used.
