Unsp inj extn musc/fasc/tend finger at wrs/hnd lv, sequela

This code signifies a long-term or late-effect complication resulting from an unspecified injury to the extensor muscle, fascia, or tendon of any finger other than the thumb, occurring at the wrist or hand level. This could include persistent pain, weakness, limited range of motion, or deformity that developed as a consequence of an initial injury.

Apply this code when documenting a patient presenting with a chronic or residual condition directly attributable to a past, unspecified injury of the extensor structures of a finger (excluding the thumb) at the wrist or hand. This is appropriate when the acute phase of the original injury has passed, and the current encounter addresses the lasting effects.

• Always sequence this code second, following the code for the primary sequela condition (e.g., chronic pain, contracture).
• Ensure documentation clearly links the current condition to a previous, unspecified extensor injury of the specified finger and location.
• Avoid using this code for acute injuries; it is strictly for sequelae.
