Unspecified dislocation of right thumb, initial encounter

This diagnosis code signifies a dislocated right thumb where the specific joint involved (e.g., carpometacarpal, metacarpophalangeal, or interphalangeal) is not documented. It indicates the initial treatment or active phase of care for this injury.

This code is appropriate when a patient presents with a dislocated right thumb, and the medical record does not specify the exact anatomical location of the dislocation within the thumb. It should be used for the first encounter related to this specific injury, including initial evaluation, reduction, and immediate post-reduction care.

• Only use this code when the specific joint of the thumb dislocation is truly unspecified in the documentation.
• Always strive for greater specificity if available in the medical record (e.g., S63.114A for carpometacarpal dislocation).
• Ensure the "A" seventh character is used only for the initial encounter; subsequent encounters will require different seventh characters.
