Unsp inj extn musc/fasc/tend l mid finger at forarm lv, sqla

This code signifies a long-term effect or complication resulting from an unspecified injury to the extensor muscle, fascia, or tendon of the left middle finger, specifically at the forearm level. It indicates that the initial injury has resolved, but the patient continues to experience residual symptoms or conditions directly attributable to that past trauma.

This code is appropriate for documenting chronic pain, stiffness, limited range of motion, or other persistent functional deficits in the left middle finger's extensor mechanism, located in the forearm, that are sequelae of a previous, unspecified injury. It should be used when the acute phase of the original injury has passed, and the current encounter addresses these lasting effects.

• Always ensure documentation clearly links the current condition to a past injury, even if the specific nature of the original injury was not detailed.
• This code requires a 7th character 'S' for sequela, indicating that the current encounter is for the late effects of the injury.
• Avoid using this code for acute injuries; instead, select an appropriate acute injury code from the S56 category.
