Inj extn/abdr musc/fasc/tend of r thm at forarm lv, sequela

This code signifies a long-term consequence or complication resulting from a previous injury to the extensor or abductor muscles, fascia, or tendons of the right thumb, specifically at the forearm level. This could include chronic pain, weakness, limited range of motion, or other persistent issues directly attributable to the initial trauma.

Use this code when documenting a patient presenting with a current condition that is a direct sequela of an old injury to the specified structures of the right thumb at the forearm. This is appropriate for follow-up visits addressing the chronic effects of such an injury, rather than the acute injury itself.

• Always assign this code as a secondary diagnosis, following the code for the primary condition or symptom being treated.
• Ensure documentation clearly links the current condition to a past injury of the right thumb extensors/abductors at the forearm level.
• Verify the "S" seventh character is appropriate, indicating a sequela, and not an initial encounter or subsequent encounter for the acute injury.
