S99.921A
ICD-10-CMThis code signifies an injury to the right foot where the specific nature of the injury (e.g., fracture, sprain, contusion) has not yet been determined or documented. It indicates that the patient is presenting for the initial treatment of this unknown right foot injury.
This code is appropriate for use in emergency department settings or initial physician visits when a patient presents with pain, swelling, or other symptoms of a right foot injury, but diagnostic imaging or a definitive clinical assessment has not yet identified the precise type of trauma. It can also be used when documentation explicitly states "unspecified injury of right foot."
