Sprain of unsp part of unspecified wrist and hand, sequela

This code indicates a sprain affecting an unspecified area of the wrist or hand, where the injury itself is no longer acute but has resulted in a long-term consequence or complication. It signifies that the patient is presenting for care related to a residual effect of a past wrist or hand sprain, rather than the initial injury.

This code is appropriate for encounters where a patient is being treated for a sequela (e.g., chronic pain, stiffness, limited range of motion, instability) directly attributable to a previously sustained, but now resolved, sprain of the wrist or hand. It should be used when the specific location of the original sprain within the wrist or hand was not documented or is unknown.

• Always ensure the "S" seventh character is used to denote a sequela, indicating a late effect of the injury.
• Avoid using this code for acute sprains; those require an "A" (initial encounter) or "D" (subsequent encounter) seventh character.
• Prioritize more specific codes if the exact location of the sprain (e.g., carpal, metacarpal, ligament) and laterality are documented.
