Inj extn musc/fasc/tend l mid finger at wrs/hnd lv, sequela

This code signifies a long-term complication or residual effect stemming from a previous injury to the extensor muscle, fascia, or tendon of the left middle finger. The original injury occurred at the wrist or hand level. This sequela could manifest as chronic pain, stiffness, weakness, or limited range of motion in the affected digit.

Apply this code when documenting a current condition that is a direct consequence of an old injury to the extensor structures of the left middle finger. This is appropriate for follow-up visits addressing persistent issues after the initial acute injury has healed. Examples include chronic tenosynovitis, adhesions, or contractures resulting from a past laceration or crush injury.

• Always use a seventh character of 'S' for sequela when the current condition is a residual effect of a past injury.
• Ensure documentation clearly links the current problem to a previous injury of the specified anatomical site and structure.
• Do not use this code for acute injuries; refer to the appropriate acute injury code for initial encounters.
