Unsp inj extn musc/fasc/tend l lit 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 little finger. The injury occurred at the wrist or hand level, and the patient is now experiencing residual symptoms or conditions directly attributable to the original trauma.

Use this code when documenting a patient presenting with a chronic issue, such as pain, weakness, limited range of motion, or deformity, in the left little finger that is a direct consequence of a past, unspecified extensor injury. This applies when the initial acute injury has healed, but its lasting effects are being treated or evaluated.

• Requires a seventh character of 'S' to indicate sequela, meaning the patient is seen for a complication or residual effect of a previous injury.
• Only use when the specific nature of the original extensor injury (e.g., laceration, strain) is not documented or is unknown.
• Ensure documentation clearly links the current condition to a prior injury of the left little finger's extensor mechanism at the wrist or hand.
