Inj extn musc/fasc/tend r little finger at wrs/hnd lv, sqla

This code signifies a long-term or residual effect from a previous injury to the extensor muscle, fascia, or tendon of the right little finger. This injury is specifically located at the wrist or hand level, indicating a healed or chronic condition rather than an acute event.

Apply this code when documenting a patient presenting with ongoing symptoms or complications directly attributable to a past injury of the extensor structures of the right little finger. This includes conditions like chronic pain, weakness, limited range of motion, or scar tissue formation resulting from the original trauma. It is appropriate for follow-up encounters after the initial acute injury has resolved.

• Always use in conjunction with an external cause code (V00-Y99) to specify the original injury mechanism, if known.
• Ensure documentation clearly states the injury is a "sequela" or "late effect" and not an acute injury.
• Verify the affected digit is the right little finger and the injury site is at the wrist or hand level.
