Strain flxr musc/fasc/tend l little fngr at wrs/hnd lv, subs

This diagnosis code indicates a non-traumatic overstretching or tearing of the flexor muscles, fascia, and/or tendons specifically located in the left little finger, affecting the wrist and hand region. It signifies an injury that occurred previously and the patient is now receiving follow-up care, such as rehabilitation, cast changes, or medication adjustments.

Use this code for patients presenting for subsequent treatment of a previously diagnosed strain of the flexor structures of the left little finger at the wrist/hand level. This includes scenarios where the patient is undergoing physical therapy, occupational therapy, or follow-up evaluations after the initial injury and acute treatment phase.

• Ensure the documentation clearly specifies the left little finger and the flexor structures.
• Verify that the encounter is for subsequent care, not the initial injury or a sequela.
• Confirm the injury site is at the wrist and hand level, not just the finger itself.
