Unsp inj extn musc/fasc/tend r rng fngr at wrs/hnd lv, sqla

This code signifies a long-term or residual effect from an unspecified injury to the extensor muscle, fascia, or tendon of the right ring finger. The injury occurred at the wrist or hand level, and the patient is now presenting with a complication or lasting symptom of that initial trauma.

Use this code when documenting a current condition that is a direct consequence of a previous injury to the specified extensor structures of the right ring finger. This applies to situations where the acute injury has resolved, but the patient continues to experience issues such as weakness, limited range of motion, pain, or deformity related to the original trauma.

• Always assign a "sequela" code when the condition being treated is a residual effect of a past injury, not the acute injury itself.
• Ensure documentation clearly links the current symptom or condition to a previous injury of the right ring finger extensor structures.
• Avoid using this code for acute injuries; instead, select an appropriate acute injury code from the S66.3 category.
