Closed Treatment of a Broken Breastbone

Maryland rates for HCPCS 21820

Nonsurgical management of a fractured breastbone (sternum), typically involving pain control, activity modification, and monitoring rather than an operation to realign the bone. Most sternum fractures are treated this way because the bone is naturally held in place by the rib cage and surrounding cartilage. Imaging may be used to confirm the fracture and check for injury to the heart or lungs, but no incision or surgical fixation is performed.
