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

This code indicates a long-term complication or late effect resulting from an unspecified injury to the intrinsic muscles, fascia, or tendons of the left middle finger. The injury occurred at the wrist or hand level, and the patient is now presenting with a residual condition directly attributable to that past injury.

Use this code when documenting a sequela, such as chronic pain, stiffness, weakness, or deformity, that is a direct consequence of an old, unspecified injury to the intrinsic structures of the left middle finger. This applies when the initial acute injury has healed, but its lasting effects are still being treated or evaluated.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, scar contracture).
• Ensure documentation clearly links the current condition to a past injury of the intrinsic muscles, fascia, or tendons of the left middle finger.
• Verify that the injury location is specified as the wrist and hand level, and the affected digit is the middle finger.
