Strain flexor musc/fasc/tend l mid finger at forarm lv, init

This code signifies a non-traumatic overstretching or tearing of the flexor muscles, fascia, or tendons specifically affecting the middle finger of the left hand, with the injury located at the forearm level. This type of injury often results in pain, swelling, and limited range of motion in the affected finger and hand.

Apply this code for initial encounters when documenting a sprain or strain of the flexor structures of the left middle finger, where the injury site is proximal to the wrist but distal to the elbow. This typically occurs due to sudden forceful movements or repetitive strain.

• Ensure the documentation clearly specifies "left" middle finger and "forearm level" for anatomical accuracy.
• Confirm the encounter is the "initial" treatment for this specific injury. Subsequent encounters will require a different seventh character.
• Distinguish between a strain (muscle/tendon/fascia) and a sprain (ligament) as they have different code categories.
