DME Prior Authorization in South Carolina: Medicare, Medicaid, and BCBS Requirements

Why Prior Authorization Matters After Discharge

Your parent is being discharged from a South Carolina hospital and needs durable medical equipment — a hospital bed, wheelchair, oxygen concentrator, or patient lift — delivered to the home before they arrive. The discharge planner says the order has been placed. But three days later, the DME supplier calls to say the equipment is on hold pending "prior authorization."

Prior authorization (PA) is a payer review that applies to some items before the supplier can receive payment. Whether it applies, what documentation is needed, and whether delivery can occur before approval depend on the item and coverage. Understanding how PA works across different coverage types in South Carolina prevents the gap between discharge and equipment delivery that drives hospital readmissions.

Medicare DME Prior Authorization

Medicare Part B covers medically necessary durable medical equipment when ordered by a physician and supplied by a Medicare-enrolled DME supplier. However, certain categories require prior authorization before Medicare will pay:

The current Medicare PA list is item-specific. Certain power mobility devices, pressure-reducing support surfaces, and orthotic devices require PA, but the applicable HCPCS code and current CMS list control. Do not rely on a generic equipment list.

For items requiring PA, the ordering practitioner or supplier submits a request with clinical documentation supporting medical necessity. Review timelines depend on the item and the applicable Medicare process, so ask the supplier or discharge planner for the current expected timing.

The face-to-face requirement: Some DME categories also require a face-to-face examination and written order before delivery. Confirm the current requirement for the specific item; a prescription alone may not be sufficient.

South Carolina Medicaid (Healthy Connections) DME Requirements

For Medicaid-covered DME in South Carolina, the prior authorization process runs through SCDHHS and its contracted DME management system. Key differences from Medicare:

• The PA requirement depends on the specific item and Healthy Connections program rules — confirm it with the supplier and SCDHHS DME guidance
• The ordering physician must be an enrolled Medicaid provider in South Carolina
• Processing times: ask the supplier or hospital DME coordinator for the current timeframe for the request
• Dual-eligible patients (Medicare + Medicaid): Medicare is billed first as the primary payer. Medicaid may cover copays, deductibles, or items Medicare doesn't cover, but each side has its own PA requirements

If your parent is on Medicaid and being discharged, ask the hospital's DME coordinator specifically: "Has the Medicaid PA been submitted, and when do we expect approval?" Don't assume the Medicare PA (if applicable) covers the Medicaid side.

BlueCross BlueShield of South Carolina

Many South Carolina residents carry BlueCross BlueShield (BCBS) as their primary or supplemental insurance, including those on Medicare Advantage plans administered by BCBS. BCBS of South Carolina's PA requirements differ from traditional Medicare:

• BCBS maintains separate plan requirements. For certain commercial small-group and individual/Marketplace plans with group-number prefixes 61, 62, 64, and 65, BCBS of South Carolina's 2026 notice says all DME and home health services require prior authorization through Integrated Home Care Services (IHCS), effective August 1, 2026
• Other plan types can have different rules, so confirm the member's plan, network, and authorization process before ordering

For patients on a BCBS Medicare Advantage plan, check that plan's current prior-authorization and network rules rather than relying on Original Medicare rules alone. The discharge planner needs to verify the specific plan requirements.

Preventing DME Delays at Discharge

The most important thing you can do as a family member:

1. Ask the discharge planner on day one: "What DME will my parent need at home, and has the prior authorization been started?" Don't wait until discharge day.
2. Confirm the supplier is Medicare-enrolled. For Medicare Advantage or private insurance, also confirm the plan's network and authorization rules.
3. Get the PA reference number before discharge. If the hospital says PA is approved, ask for the authorization number and the expiration date. PAs have time limits — if discharge is delayed, the PA may expire.
4. Have a backup plan. If equipment won't arrive by discharge day, ask the hospital if they can lend or rent equipment for the interim period. Some South Carolina Area Agencies on Aging maintain loaner equipment programs for exactly this situation.

Our South Carolina Hospital Discharge Guide includes a DME ordering checklist tied to the discharge timeline — covering what to verify with the hospital, how to confirm PA status across different insurance types, and the specific steps for ensuring equipment is in the home before your parent arrives. When a missing hospital bed or oxygen concentrator is the only thing standing between your parent and a safe discharge, knowing the PA process eliminates the most common source of delay.
