Sprain of MTP joint of unsp lesser toe(s), sequela

This code describes a long-term complication or late effect resulting from a sprain of the joint connecting the metatarsal bone to the phalanx (toe bone) in any of the lesser toes (toes 2-5). This indicates that the initial injury has resolved, but the patient is still experiencing residual symptoms or conditions directly attributable to that past sprain.

Use this code when documenting a patient presenting with chronic pain, stiffness, instability, or other persistent issues in a lesser metatarsophalangeal joint, where these symptoms are identified as a direct consequence of a previously sustained sprain. This applies when the acute phase of the original injury has passed, and the current encounter addresses these lasting effects.

• Requires a seventh character "S" to indicate sequela, meaning the current condition is a residual effect of a past injury.
• Ensure documentation clearly links the current symptoms to a prior metatarsophalangeal joint sprain of a lesser toe.
• Do not use for acute sprains; those would be coded with an initial or subsequent encounter seventh character.
