Sprain of calcaneofibular ligament of right ankle, subs

This code describes an injury to the calcaneofibular ligament, a key stabilizing structure on the outer side of the right ankle, specifically when the patient is receiving follow-up care for this sprain. It indicates a tear or stretching of this ligament, which often results from an inversion injury. The "subsequent encounter" denotes that the patient is beyond the initial phase of injury and is undergoing active treatment or recovery.

This code is appropriate for use when a patient presents for ongoing management of a previously diagnosed calcaneofibular ligament sprain of the right ankle. This includes visits for physical therapy, re-evaluation of healing progress, cast changes, or follow-up appointments after initial treatment. It should be selected for any encounter after the initial diagnosis and treatment has been established.

• Ensure documentation clearly specifies the right ankle and the calcaneofibular ligament.
• Verify the encounter type is "subsequent" and not initial or sequela.
• Always link this diagnosis code to the appropriate CPT codes for the services rendered during the follow-up visit.
