MAD Hospital Coverage & Emergency Criteria
MAD hospital coverage criteria and limits
MAD covers medically necessary inpatient, outpatient, and emergency services with specific coverage rules, exclusions, and reimbursement methodologies.
Prior authorization / utilization review
- Certain procedures and services require prior authorization from MAD or its designee (examples include transfers between DRG hospitals, PPS-exempt psychiatric inpatient stays, rehabilitation and specialty inpatient stays).
- Admission and continued stay reviews are required for specified inpatient stays; services with prior authorization remain subject to utilization review and providers may request re-review and reconsideration of utilization review decisions per MAD-953.
Emergency room coverage and reimbursement criteria
MAD covers medically necessary emergency room services within program scope, with limitations and exceptions.
Prior authorization
- Some services or procedures performed in an emergency room setting require prior approval from MAD or its designee.
- Procedures that require prior approval in non-emergency settings also require prior approval when performed in emergency settings.
Coding, Reimbursement Basis, and Adjustments
Prior Authorization, Utilization Review, and Reconsideration
Prior authorization and utilization review — provider obligations
Certain procedures or services require prior authorization from MAD or its designee; examples include all transfers between DRG-reimbursed acute care hospitals, inpatient stays in PPS-exempt psychiatric units, inpatient stays in rehabilitation or specialty hospitals (admission and continued stay reviews), and outpatient physical, occupational, and speech therapy services. Services for which prior authorization was obtained remain subject to utilization review at any point in the payment process. Providers are responsible for accessing and following utilization review instructions and for complying with authorization requirements, including enrollment with coordinated services contractors when applicable.
- All transfers from one acute care DRG-reimbursed hospital to another require prior authorization.
- All inpatient stays for PPS-exempt psychiatric units and rehabilitation or specialty hospitals require admission and continued stay reviews.
- Outpatient physical, occupational, and speech therapy services require prior authorization.
- Services with prior authorization remain subject to utilization review at any point in the payment process.
Reconsideration and eligibility verification
A provider may request a re-review and reconsideration if they disagree with a prior authorization denial or other utilization review decision. Prior authorization does not guarantee that the recipient is eligible for MAD services; providers must verify recipient eligibility and any other health insurance at the time services are furnished.
- Request re-review and reconsideration per MAD-953 when disputing a utilization review decision.
- Verify recipient MAD eligibility and other health insurance at the time services are furnished — prior authorization alone is not proof of eligibility.
Prior authorization for emergency room procedures
Some services or procedures performed in an emergency room setting require prior approval from MAD or its designee; procedures that require prior approval in non-emergency settings also require prior approval when performed in the ER. Noncovered emergency services are listed separately and include diagnostic/ancillary services not medically necessary as emergency services and services to individuals not eligible on the date of service.
- Prior authorization requirements that apply in non-emergency settings also apply in emergency settings.
- MAD does not cover diagnostic or ancillary services that are not medically necessary as emergency services, nor services to individuals not eligible on the date of service.
