Unspecified dislocation of left thumb, initial encounter

This code signifies a left thumb dislocation where the specific type of dislocation (e.g., carpometacarpal, metacarpophalangeal, interphalangeal) is not documented by the provider. It indicates that the thumb bones are no longer properly aligned at a joint, affecting the left hand.

Apply this code when the medical record clearly states a dislocation of the left thumb, but lacks further detail regarding the specific joint involved. This is appropriate for the initial visit or encounter for this injury, before definitive treatment or further diagnostic clarification.

• Ensure the documentation specifies "left thumb" and "dislocation" without further anatomical detail.
• Verify that this is the patient's first encounter for this specific injury.
• If the specific joint (e.g., MCP, IP) is documented, a more specific code from the S63.10- series should be used.
