Strain of flexor musc/fasc/tend at forarm lv, left arm, subs

This code signifies a muscle, fascia, or tendon strain affecting the flexor compartment of the left forearm, excluding the wrist and hand. It indicates an injury to the muscles responsible for bending the wrist and fingers, such as the flexor carpi radialis or flexor digitorum superficialis, that is currently under active treatment or healing.

Use this code for follow-up encounters when a patient is receiving ongoing care for a left forearm flexor strain. This includes situations like physical therapy sessions, re-evaluations of the injury, or medication management during the healing phase after the initial acute injury.

• Ensure the documentation clearly specifies "left arm" and "subsequent encounter" for this specific code.
• Distinguish from initial encounters (A) or sequela (S) using the appropriate 7th character.
• Verify the injury is to a flexor muscle/tendon in the forearm, not the wrist or hand, to avoid miscoding.
