Strain of flexor musc/fasc/tend finger at wrs/hnd lv, subs

This code indicates a non-traumatic injury to the flexor muscles, their surrounding fascia, or tendons in any finger other than the thumb, occurring at the wrist or hand level. This injury involves overstretching or tearing of these tissues, resulting in pain, swelling, and impaired finger movement. The "D" suffix signifies that this is a subsequent encounter for care after the initial treatment phase.

Use this code when documenting follow-up care for a patient who previously sustained a strain to the flexor structures of a finger (excluding the thumb) in the hand or wrist region. This includes visits for physical therapy, medication management, or re-evaluation of the injury during the healing or recovery phase. It is appropriate for encounters after the initial diagnosis and treatment.

• Ensure the documentation clearly specifies a strain, not a sprain or tear, of the flexor structures.
• Verify the injury location is "other finger" (i.e., not the thumb) and at the "wrist and hand level."
• Confirm the encounter type is for subsequent care, not the initial injury or sequela.
