Unspecified subluxation of left index finger, init encntr

This code indicates a partial dislocation or misalignment of a joint within the left index finger where the specific joint involved (e.g., metacarpophalangeal, proximal interphalangeal, distal interphalangeal) is not documented. It signifies that the joint surfaces are no longer in complete apposition but still maintain some contact.

Use this code when documentation clearly states a subluxation of the left index finger but lacks further specificity regarding the exact joint affected. This is appropriate for initial evaluations and treatments of such an injury.

• Ensure the documentation specifies "left index finger" and "subluxation" without further joint detail.
• Confirm the encounter is for the initial treatment of this injury; subsequent encounters will require a different 7th character.
• If the specific joint (e.g., MCP, PIP, DIP) is documented, a more precise code from the S63.20- series should be used.
