Lacerat extn/abdr musc/fasc/tend of l thm at forarm lv, sqla

This code signifies a healed injury or a late effect resulting from a laceration to the extensor or abductor muscles, fascia, and/or tendons of the left thumb, specifically at the forearm level. This indicates that the initial acute injury has resolved, but the patient continues to experience residual symptoms or complications directly attributable to the original laceration.

Apply this code when documenting a patient presenting with ongoing issues such as chronic pain, weakness, limited range of motion, or other functional deficits in the left thumb or hand, where these issues are a direct consequence of a previously sustained laceration to the specified structures at the forearm level. This is appropriate for follow-up encounters after the initial healing period.

• Ensure documentation clearly links the current symptoms to the historical laceration.
• Verify the injury location is specifically the left thumb at the forearm level.
• Confirm the "S" seventh character is appropriate for sequela, indicating a late effect.
