Strain intrns musc/fasc/tend l mid fngr at wrs/hnd lv, subs

This code signifies a non-traumatic overstretching or tearing of the intrinsic muscles, fascia, or tendons within the left middle finger, specifically at the wrist and hand level. This injury does not involve a fracture or dislocation but rather damage to the soft tissues responsible for fine motor control of the digit.

Apply this code for follow-up encounters when a patient is receiving active treatment or recovering from a previously diagnosed strain of the intrinsic muscles, fascia, or tendons of the left middle finger. This includes situations such as physical therapy, re-evaluation of healing, or management of ongoing symptoms after the initial injury.

• Ensure documentation specifies the left middle finger and the "at wrist and hand level" anatomical location.
• Confirm the encounter is "subsequent" (D) and not initial (A) or sequela (S).
• Distinguish from sprains (ligamentous injury) or more severe injuries like ruptures.
