Dislocation of interphalangeal joint of right thumb, sequela

This code signifies a long-term or late-effect condition resulting from a previous dislocation of the joint between the two bones of the right thumb. It indicates that the initial injury has resolved, but the patient continues to experience residual symptoms or complications directly attributable to that past dislocation.

Use this code when documenting a patient presenting with chronic pain, stiffness, limited range of motion, instability, or other persistent issues in the right thumb's interphalangeal joint, and the medical record clearly links these issues to a previously treated dislocation. This code is appropriate for follow-up encounters occurring after the initial healing period of the acute injury.

• Always assign a secondary code for the specific sequela being treated (e.g., chronic pain, osteoarthritis).
• Ensure documentation explicitly states the current condition is a "sequela of" or "due to previous" a right thumb interphalangeal joint dislocation.
• This code is for the sequela and should not be used for acute or initial treatment of the dislocation itself.
