Unspecified dislocation of unspecified thumb, init encntr

This code signifies a thumb dislocation where the specific joint involved (e.g., carpometacarpal, metacarpophalangeal, interphalangeal) is not documented, nor is the cause or type of dislocation. It indicates the initial treatment or evaluation of such an injury.

This code is appropriate when a patient presents with a dislocated thumb, but the medical record lacks the detailed information required to specify the exact joint affected or the nature of the dislocation. It should be used for the first encounter related to this particular injury.

• Only use this code when documentation is insufficient to specify the dislocated thumb joint.
• Always strive for more specific codes if the documentation allows (e.g., S63.11- for carpometacarpal, S63.12- for metacarpophalangeal).
• Ensure the "A" seventh character is used only for the initial encounter for active treatment of the injury.
