Strain extn musc/fasc/tend fngr,unsp fngr at forarm lv, subs

This code signifies a non-traumatic overstretching or tearing of the extensor muscles, fascia, or tendons in an unspecified finger, located at the forearm level. This injury does not involve a fracture or dislocation and is being treated in a follow-up encounter after initial care.

Apply this code for patients presenting for subsequent treatment of a previously diagnosed extensor strain in the finger, where the specific finger involved is not documented. This would include follow-up visits for physical therapy, medication management, or re-evaluation of the healing process.

• Ensure documentation specifies "subsequent encounter" for this injury.
• Verify that the injury is a strain and not a more severe tear or rupture.
• If the specific finger is identified, a more precise code should be used.
