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

This code signifies a long-term or late-effect complication resulting from an unspecified injury to the extensor muscle, fascia, or tendon of the left middle finger. The injury occurred specifically at the wrist or hand level, and the "sequela" indicates that the patient is now experiencing residual problems directly attributable to that initial injury.

This code is appropriate when documenting chronic pain, stiffness, limited range of motion, or other persistent functional deficits in the left middle finger, wrist, or hand, which are directly linked to a past, unspecified extensor injury. It should be used after the acute phase of the original injury has passed and the patient is being treated for the lasting consequences.

• Always ensure documentation clearly links the current condition to a previous injury of the left middle finger extensor structures.
• This "S" seventh character indicates a sequela, meaning the patient is being treated for the late effects of the injury.
• Avoid using this code for acute injuries; instead, select an appropriate acute injury code with the correct seventh character.
