Section 412.42 - Limitations on charges to beneficiaries(a)Prohibited charges. A hospital may not charge a beneficiary for any services for which payment is made by Medicare, even if the hospital's costs of furnishing services to that beneficiary are greater than the amount the hospital is paid under the prospective payment systems.(b)Permitted charges-Stay covered. A hospital receiving payment under the prospective payment systems for a covered hospital stay (that is, a stay that includes at least one covered day) may charge the Medicare beneficiary or other person only for the following:(1) The applicable deductible and coinsurance amounts under §§ 409.82 , 409.83 , and 409.87 of this chapter.(2) Noncovered items and services, furnished at any time during a covered stay, unless they are excluded from coverage only on the basis of the following: (i) The exclusion of custodial care under § 411.15(g) of this chapter (see paragraph (c) of this section for when charges may be made for custodial care).(ii) The exclusion of medically unnecessary items and services under § 411.15(k) of this chapter (see paragraphs (c) and (d) of this section for when charges may be made for medically unnecessary items and services).(iii) The exclusion under § 411.15(m) of this chapter of nonphysician services furnished to hospital inpatients by other than the hospital or a provider or supplier under arrangements made by the hospital.(iv) The exclusion of items and services furnished when the patient is not entitled to Medicare Part A benefits under subpart A of part 406 of this chapter (see paragraph (e) of this section for when charges may be made for items and services furnished when the patient is not entitled to benefits).(v) The exclusion of items and services furnished after Medicare Part A benefits are exhausted under § 409.61 of this chapter (see paragraph (e) of this section for when charges may be made for items and services furnished after benefits are exhausted).(c)Custodial care and medically unnecessary inpatient hospital care. A hospital may charge a beneficiary for services excluded from coverage on the basis of § 411.15(g) of this chapter (custodial care) or § 411.15(k) of this chapter (medically unnecessary services) and furnished by the hospital after all of the following conditions have been met: (1) The hospital (acting directly or through its utilization review committee) determines that the beneficiary no longer requires inpatient hospital care. (The phrase "inpatient hospital care" includes cases where a beneficiary needs a SNF level of care, but, under Medicare criteria, a SNF-level bed is not available. This also means that a hospital may find that a patient awaiting SNF placement no longer requires inpatient hospital care because either a SNF-level bed has become available or the patient no longer requires SNF-level care.)(2) The attending physician agrees with the hospital's determination in writing (for example, by issuing a written discharge order). If the hospital believes that the beneficiary does not require inpatient hospital care but is unable to obtain the agreement of the physician, it may request an immediate review of the case by the QIO as described in § 405.1208 of this chapter. Concurrence by the QIO in the hospital's determination will serve in lieu of the physician's agreement.(3) The hospital (acting directly or through its utilization review committee) notifies the beneficiary (or his or her representative) of his or her discharge rights in writing consistent with § 405.1205 and notifies the beneficiary, in accordance with § 405.1206 of this chapter (if applicable) that in the hospital's opinion, and with the attending physician's concurrence or that of the QIO, the beneficiary no longer requires inpatient hospital care.(4) If the beneficiary remains in the hospital after the appropriate notification, and the hospital, the physician who concurred in the hospital determination on which the notice was based, or QIO subsequently finds that the beneficiary requires an acute level of inpatient hospital care, the hospital may not charge the beneficiary for continued care until the hospital once again determines that the beneficiary no longer requires inpatient care, secures concurrence, and notifies the beneficiary, as required in paragraphs (c)(1), (c)(2), and (c)(3) of this section.(d)Medically unnecessary diagnostic and therapeutic services. A hospital may charge a beneficiary for diagnostic procedures and studies, and therapeutic procedures and courses of treatment (for example, experimental procedures) that are excluded from coverage under § 411.15(k) of this chapter (medically unnecessary items and services), even though the beneficiary requires continued inpatient hospital care, if those services are furnished after the beneficiary (or the person acting on his or her behalf) has acknowledged in writing that the hospital (acting directly or through its utilization review committee and with the concurrence of the intermediary) has informed him or her as follows:(1) In the hospital's opinion, which has been agreed to by the intermediary, the services to be furnished are not considered reasonable and necessary under Medicare.(2) Customary charges will be made if he or she receives the services.(3) If the beneficiary receives the services, a formal determination on the validity of the hospital's finding is made by the intermediary and, to the extent that the decision requires the exercise of medical judgment, the QIO.(4) The determination is appealable by the hospital, the attending physician, or the beneficiary under the appeals procedure that applies to determinations affecting Medicare Part A payment.(5) The charges for the services will be invalid and, to the extent collected, will be refunded by the hospital if the services are found to be covered by Medicare.(e)Services furnished on days when the individual is not entitled to Medicare Part A benefits or has exhausted the available benefits. The hospital may charge the beneficiary its customary charges for noncovered items and services furnished on outlier days (as described in Subpart F of this part) for which payment is denied because the beneficiary is not entitled to Medicare Part A or his or her Medicare Part A benefits are exhausted.(1) If payment is considered for outlier days, the entire stay is reviewed and days up to the number of days in excess of the outlier threshold may be denied on the basis of nonentitlement to Part A or exhaustion of benefits.(2) In applying this rule, the latest days will be denied first.(f)Differential for private room or other luxury services. The hospital may charge the beneficiary the customary charge differential for a private room or other luxury service that is more expensive than is medically required and is furnished for the personal comfort of the beneficiary at his or her request (or the request of the person acting on his or her behalf).(g)Review.(1) The QIO or intermediary may review any cases in which the hospital advises the beneficiary (or the person acting on his or her behalf) of the noncoverage of the services in accordance with paragraph (c)(3) or (d) of this section.(2) The hospital must identify such cases to the QIO or intermediary in accordance with CMS instructions.50 FR 12741, Mar. 29, 1985, as amended at 50 FR 35688, Sept. 3, 1985; 54 FR 41747, Oct. 11, 1989; 57 FR 39821, Sept. 1, 1992; 71 FR 48137, Aug. 18, 2006; 71 FR 68722, Nov. 27, 2006; 85 FR 72909, Nov. 16, 2020
