Strain of extn musc/fasc/tend at forarm lv, right arm, init

This code signifies a non-traumatic overstretching or tearing of the muscle fibers, fascia, or tendons of an extensor muscle in the right forearm. It specifically excludes the flexor muscles and indicates the initial presentation of this injury.

Apply this code for patients presenting with pain, swelling, or limited range of motion in the right forearm due to an acute strain of an extensor muscle or its associated tissues. This is appropriate for injuries sustained during activities like repetitive gripping, lifting, or sports that stress the forearm extensors.

• Ensure the documentation specifies "strain" and not a sprain, tear, or other injury type.
• Verify the injury is to an "extensor" muscle/tendon and located in the "right forearm."
• Confirm this is the "initial encounter" for this specific injury, even if the patient has had previous forearm issues.
