Hospital-Issued Notices of Noncoverage (HINN) inform patients that they will be responsible for the bill if they choose to stay in the hospital when the care they are receiving or about to receive will not be covered by Medicare. If hospitals don't give a HINN when services aren't covered by Medicare, they can't bill patients for services later on. CMS gives hospitals the option of using Condition Code 44 to change a patient's status from inpatient to outpatient to correct an unnecessary admission, then collect payment from Medicare for Medicare Part B services. All HINNs must be signed by the patient and a copy included in their file. If the patient refuses to sign, a copy should be placed in the file with a notation of the refusal to sign.
