Strain intrns musc/fasc/tend r lit fngr at wrs/hnd lv, subs

This code signifies a non-traumatic overstretching or tearing of the small muscles, their surrounding connective tissue, or tendons located within the right little finger at the wrist and hand level. This injury results in pain, swelling, and impaired function of the affected digit. The "subsequent encounter" indicates the patient is receiving follow-up care for an injury that has already been treated.

Use this code for patients presenting for ongoing treatment, such as physical therapy, re-evaluation, or medication management, for a previously diagnosed strain of the intrinsic muscles, fascia, or tendons of the right little finger. This applies after the initial active treatment phase has concluded.

• Ensure documentation clearly specifies the right little finger and the "subsequent encounter" status.
• Distinguish this from initial encounters (A) or sequela (S) codes.
• Verify the injury is a strain, not a sprain, fracture, or dislocation.
