Unspecified dislocation of unspecified thumb, sequela

This code indicates a long-term complication or late effect stemming from an unspecified dislocation of an unspecified thumb. It signifies that the initial injury has healed, but the patient is still experiencing residual problems directly attributable to that past dislocation. These sequelae could include chronic pain, stiffness, limited range of motion, or instability.

This code is appropriate when documenting a patient presenting with a current condition that is a direct consequence of a thumb dislocation that occurred in the past and has since healed. It should be used for follow-up encounters addressing these persistent issues, not for the initial acute injury or its immediate healing phase.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., chronic pain, osteoarthritis).
• Ensure documentation clearly links the current condition to a past, unspecified thumb dislocation.
• Avoid using this code for acute or subacute dislocations; those require codes from the acute injury section.
