Unsp inj intrns musc/fasc/tend unsp fngr at wrs/hnd lv, sqla

This code signifies a long-term complication or residual effect from an unspecified injury to the small muscles, connective tissue, or tendons within an unspecified finger, specifically at the wrist or hand level. It indicates that the exact nature of the original injury to these intrinsic structures is unknown, and the patient is now experiencing a sequela.

Use this code when documenting a chronic or late effect of an intrinsic finger muscle, fascia, or tendon injury where the original injury details are unavailable or not specified. This is appropriate for follow-up encounters addressing persistent symptoms or complications arising from such an injury.

• Always strive for a more specific code if the finger, muscle/tendon, and initial injury type are known.
• This code requires a seventh character of 'S' for sequela, indicating a late effect.
• Ensure documentation clearly supports a sequela and the unspecified nature of the original injury.
