Lacerat long flexor musc/fasc/tend thmb at wrs/hnd lv, sqla

This code signifies a long-term complication or late effect resulting from a laceration to the long flexor muscle, fascia, and/or tendon of an unspecified thumb. This injury occurred at the wrist or hand level, and the sequela indicates a residual condition or problem directly attributable to the original laceration, even after the acute phase of healing has passed.

Apply this code when documenting a chronic issue, such as persistent pain, stiffness, limited range of motion, or functional impairment, that is a direct consequence of a previously sustained laceration to the thumb's long flexor structures. This code is appropriate for follow-up encounters where the patient is being treated for the lasting effects of the original injury.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the previous laceration of the thumb's long flexor.
• Verify the injury location is at the wrist or hand level and involves the long flexor structures of the thumb.
