Same-Day Registration and Retroactive Eligibility
A 54-year-old patient presents at 4:40 p.m. Friday to an outpatient imaging center for a CT scan ordered urgently by her PCP. She states she lost her job two months ago and has no insurance, but she believes she qualifies for the state Medicaid program and has a pending application (submitted 18 days ago) with no determination yet. The center's policy requires a signed ABN and a point-of-service estimate before non-emergent imaging. The registration clerk is new and the supervisor has already left. The order is marked 'urgent, within 72 hours.' The patient has $40 cash and asks to pay 'whatever she can' now. The imaging center is in-network with commercial plans but a Medicaid enrollment application for the facility was submitted and is not yet approved.
1. What should the registrar do at the point of service regarding the ABN, the estimate, and collecting payment?
Read the worked answer
The ABN is not the right instrument here. An ABN applies to items/services that Medicare may not cover as reasonable and necessary; it is not a general consent to bill an uninsured patient. The correct sequence:
- Screen for presumptive/retroactive eligibility. A pending Medicaid application with a submission date is a documented eligibility pathway. Many states allow retroactive coverage up to 3 months before the application month, so the service date may be covered retroactively.
- Do not delay the urgent service for financial clearance. The clinical urgency (72-hour window) governs. Register the patient and document the pending application, submission date, and any case/reference number.
- Provide a good-faith estimate consistent with the No Surprises Act for uninsured/self-pay patients, and document that it was given.
- Accept the $40 as a partial payment and apply it to the account; do not represent it as a settlement or as full payment.
- Flag the account for follow-up on the Medicaid determination and for retroactive billing if approved. Do not send to collections while eligibility is unresolved.
2. The facility's own Medicaid enrollment is not yet approved. How does that affect the plan for this account?
Read the worked answer
It creates a sequencing problem the registrar cannot solve at the desk, but it must be documented so the account is not mishandled later.
- If the patient's Medicaid is approved but the facility is not yet an enrolled Medicaid provider, the facility generally cannot bill Medicaid for that date of service. Billing before enrollment approval risks claim rejection and, if billed improperly, compliance exposure.
- The account should be placed in a hold/pending status tied to both the patient's determination and the facility's enrollment effective date. If the facility enrollment is approved with a retroactive effective date covering the service, the claim can then be submitted.
- If the facility cannot bill Medicaid for the date, the account must be handled under the self-pay/financial assistance policy - not simply written off without documentation.
- The registrar should escalate to the supervisor/manager on the next business day: this is a policy gap (new clerk, no after-hours escalation for eligibility-pending urgent cases), and the fix is a documented workflow, not an ad hoc decision.
