Other sprain of sternum, subsequent encounter

This code signifies a sprain of the sternum, or breastbone, that is not specifically classified as a costochondral or sternoclavicular sprain. It indicates damage to the ligaments connecting the sternum to other structures, such as the ribs or clavicle, or within the sternal body itself. The "D" suffix denotes that this is a subsequent encounter for treatment or recovery.

Apply this code when a patient presents for follow-up care, rehabilitation, or further evaluation of a previously diagnosed sternal sprain that is not specified as a costochondral or sternoclavicular injury. This includes scenarios where the patient is receiving physical therapy, medication management, or imaging to monitor healing after the initial injury.

• Ensure documentation clearly states "subsequent encounter" for the sternal sprain.
• Verify that the sprain is not specifically identified as costochondral (S23.41-) or sternoclavicular (S23.421-).
• Always link this diagnosis code to the appropriate procedure code for the services rendered during the subsequent encounter.
