Sprain of interphalangeal joint of right thumb, sequela

This code signifies a long-term or late-effect condition resulting from a previous sprain to the interphalangeal (IP) joint of the right thumb. This could include chronic pain, stiffness, instability, or functional limitations that persist after the initial injury has healed. It indicates that the current patient encounter addresses a residual problem directly attributable to the past sprain.

Use this code when documenting a patient presenting with ongoing symptoms or complications related to a prior sprain of the right thumb's IP joint. This applies to follow-up visits for chronic pain management, physical therapy for persistent stiffness, or evaluation of long-term instability. It should be assigned when the acute phase of the injury has passed, and the current condition is a direct consequence of that past trauma.

• 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 previous right thumb IP joint sprain.
• Do not use this code for acute or subacute sprains; those require codes from the initial or subsequent encounter categories.
