Strain extn musc/fasc/tend l mid finger at forarm lv, subs

This code signifies a non-traumatic overstretching or tearing of the extensor muscle, fascia, or tendon specifically located in the left middle finger, with the injury occurring at the forearm level. It indicates that the patient is receiving follow-up care for this previously diagnosed injury, such as during a re-evaluation or ongoing treatment.

Use this code for subsequent encounters when a patient presents for ongoing management of a strain to the extensor structures of the left middle finger, where the injury site is identified as being at the forearm level. This includes follow-up appointments for physical therapy, medication adjustments, or wound checks after the initial treatment.

• Ensure documentation specifies "subsequent encounter" for this specific injury.
• Verify the laterality (left) and the specific digit (middle finger) are clearly documented.
• Confirm the injury location is at the "forearm level" to differentiate from injuries at the hand or wrist.
