Unspecified sprain of sternum, subsequent encounter

This code signifies a follow-up visit for an injury to the sternum, where the specific ligament or joint involved in the sprain was not documented. It indicates that the patient is receiving continued care for a previously diagnosed, but unspecified, sternal sprain.

Apply this code for subsequent encounters when a patient presents for ongoing treatment, rehabilitation, or follow-up of a sternal sprain that was not further specified at the initial diagnosis. This includes situations where the initial injury was documented simply as "sternal sprain" without detailing the specific anatomical structure affected.

• Ensure the "D" seventh character is appropriate for a subsequent encounter, indicating active treatment or healing phase.
• Only use this code when the specific ligament or joint involved in the sternal sprain remains unspecified in the medical record.
• If the specific sternal sprain (e.g., sternoclavicular, costosternal) is later identified, a more specific code should be used.
