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

This code signifies a non-traumatic overstretching or tearing of the extensor muscles, fascia, or tendons specifically affecting the left middle finger, with the injury located at the forearm level. This typically results in pain, swelling, and impaired movement of the affected digit.

Apply this code for patients presenting with a new injury to the extensor structures of the left middle finger, where the injury site is proximal to the wrist but distal to the elbow. This would include injuries sustained from repetitive strain, sudden forceful extension, or minor overexertion.

• Ensure the documentation specifies "left middle finger" and "forearm level" for accurate code assignment.
• Confirm the encounter is "initial" for this specific injury; subsequent encounters will require a different seventh character.
• Distinguish from sprains (ligamentous injury) or more severe injuries like ruptures or lacerations.
