Sprain of MTP joint of unsp great toe, sequela

This code signifies a sprain affecting the joint connecting the metatarsal bone to the phalanx of the great toe, where the specific great toe (left or right) is not documented. The "S" at the end indicates that this is a sequela, meaning it represents a late effect or complication of an earlier injury to this joint.

This code is appropriate for documenting chronic pain, stiffness, instability, or other long-term issues directly resulting from a previously sustained sprain of the great toe's metatarsophalangeal joint. It should be used when the initial acute injury has resolved, but residual problems persist.

• Always assign a sequela code when the patient is presenting for treatment of a residual condition from a past injury.
• Ensure documentation clearly links the current symptoms to a previous metatarsophalangeal joint sprain.
• Do not use this code for acute sprains; those require codes from the initial encounter or subsequent encounter categories.
