S99.921S
ICD-10-CMThis code indicates a long-term or late effect of an unspecified injury to the right foot. It is used when the original injury has healed, but residual symptoms, complications, or conditions persist as a direct result of that past trauma. The specific nature of the original injury to the right foot is not documented or is unknown.
Apply this code when a patient presents with ongoing issues, such as chronic pain, stiffness, deformity, or functional limitation, stemming from a previous, unidentifiable injury to their right foot. This is appropriate for follow-up encounters where the primary focus is managing these persistent sequelae.
