Strain extn musc/fasc/tend r little fngr at wrs/hnd lv, init

This code signifies a non-traumatic overstretching or tearing of the extensor muscles, their surrounding fascia, or the tendons specifically associated with the little finger on the right hand. The injury is located within the wrist or hand region, not extending into the forearm or more proximally.

Apply this code for acute injuries where a patient presents with pain, swelling, or limited movement in the right little finger due to a strain of its extensor mechanism. This is appropriate for the initial evaluation and treatment of such an injury, often resulting from repetitive motion, sudden forceful extension, or minor trauma.

• Ensure the documentation specifies the right little finger and the extensor mechanism.
• Verify the injury is a strain (overstretch/tear) and not a rupture or avulsion.
• Confirm the encounter is the initial one for this specific injury.
