Unsp inj extn/abdr musc/fasc/tend of r thm at forarm lv,subs

This code signifies an unspecified injury to the extensor or abductor muscles, fascia, or tendons of the right thumb, specifically at the forearm level. This indicates damage to the tissues responsible for extending or moving the thumb away from the hand, without further detail regarding the nature of the injury (e.g., strain, tear).

This code is appropriate for follow-up encounters where a patient is receiving ongoing treatment for an injury to the right thumb's extensor/abductor musculotendinous unit at the forearm level, and the specific type of injury was not documented or is still undetermined. This could include physical therapy sessions, re-evaluations, or medication management for the healing injury.

• Ensure documentation clearly specifies the right thumb and the forearm level involvement.
• Only use this code for subsequent encounters; an initial encounter would require a different 7th character.
• If the specific nature of the injury (e.g., strain, tear) is later identified, a more specific code should be used.
