1.3 CMS Notices & Billing-Compliance Rules
Key Takeaways
- An Advance Beneficiary Notice of Noncoverage (ABN) must be issued before a service when a provider believes Original Medicare Part B will deny the claim for lack of medical necessity, and it does not apply to Medicare Advantage plans
- Condition Code 44 lets a hospital change a patient's status from inpatient to outpatient/observation before discharge, but only with utilization review agreement, physician concurrence, and documentation completed prior to discharge
- The No Surprises Act (effective January 1, 2022) requires a Good Faith Estimate (GFE) of expected charges for uninsured and self-pay patients before a scheduled service
- The Medicare Secondary Payer (MSP) questionnaire at registration determines whether Medicare or another payer, such as an employer group health plan or workers' compensation, is primary
- The False Claims Act and Anti-Kickback Statute are the two anchor fraud-and-abuse laws behind CMS compliance training — both target inaccurate billing and improper financial incentives tied to referrals
Beyond EMTALA and HIPAA, the Centers for Medicare & Medicaid Services (CMS) requires a set of patient-facing notices and screening steps that protect both the patient's right to make informed financial decisions and the accuracy of what gets billed to federal programs. These notices show up constantly in CHAA exam scenarios because patient access staff are usually the ones who issue them.
Advance Beneficiary Notice of Noncoverage (ABN)
The ABN (CMS Form CMS-R-131) is a written notice given to a patient enrolled in Original Medicare (Part A/B) when the provider has reason to believe Medicare will deny payment for a specific item or service because it is not medically necessary, is experimental, or exceeds Medicare's utilization guidelines for frequency. The ABN must be issued before the service is furnished, in a way the patient can understand, and it gives the patient three financial-liability choices:
- Option 1 — Receive the item/service, have the claim submitted to Medicare, and pay if Medicare denies it.
- Option 2 — Receive the item/service and pay out of pocket, with no claim submitted to Medicare.
- Option 3 — Decline the item/service entirely.
Two important boundaries frequently tested on the CHAA exam: the ABN applies only to Original Medicare, not to Medicare Advantage (Part C) plans, which have their own separate denial-notice processes; and the ABN is not used for items or services that are always excluded from Medicare coverage (like most cosmetic procedures) — those instead may use a voluntary Notice of Exclusion from Medicare Benefits (NEMB), because there was never a coverage decision to protect the patient from.
Condition Code 44
Condition Code 44 addresses a specific timing problem: a physician writes an order for inpatient admission, but the hospital's utilization review (UR) process later determines the patient's clinical presentation actually meets outpatient or observation criteria. Condition Code 44 allows the hospital to correct the patient's status from inpatient to outpatient — but only if every one of these conditions is met before the patient is discharged:
- The change is made by the hospital's UR committee (or a physician member of it), with the concurrence of the ordering physician and the patient's attending physician.
- The change is documented in the medical record, including the rationale and the concurrence of all physicians involved.
- The patient has not yet been discharged.
If the status issue is not caught until after discharge, Condition Code 44 no longer applies — the hospital must instead use the separate Part A-to-Part B self-audit/rebilling process, which is a different, more limited mechanism. This before-versus-after-discharge distinction is one of the most commonly tested details on the CHAA exam related to patient class.
No Surprises Act & Good Faith Estimate (GFE)
The No Surprises Act, effective January 1, 2022, protects patients from unexpected out-of-network bills and requires providers and facilities to give uninsured and self-pay patients a Good Faith Estimate (GFE) of expected charges before a scheduled item or service. Key operational points for patient access:
- The GFE must reflect the expected charges for the scheduled service and any related items reasonably expected to be provided.
- Timing is tied to how far in advance the service is scheduled: the closer the service, the tighter the window the facility has to deliver the estimate, and patients can also request a GFE proactively before anything is scheduled.
- If the patient's actual bill ends up substantially higher than the GFE, the patient can pursue the patient-provider dispute resolution (PPDR) process through CMS.
The GFE is easy to confuse with the ABN on the exam — remember that the GFE is a No Surprises Act protection for uninsured/self-pay patients around cost transparency, while the ABN is a Medicare-specific notice about medical-necessity coverage risk. They serve different patients and different purposes even though both are handed to a patient before service.
Medicare Secondary Payer (MSP)
The MSP questionnaire, completed at registration (and periodically re-verified), determines whether Medicare is the primary or secondary payer for a given patient. Common triggers for Medicare to be secondary include: a working aged beneficiary (65+) covered by an employer group health plan through current employment; a disabled beneficiary under 65 covered by a large group health plan; no-fault or liability insurance situations, such as an auto accident; workers' compensation for a work-related injury; and a coordination period for patients with End-Stage Renal Disease (ESRD). Getting MSP wrong at registration causes downstream claim denials and delayed payment, so the questionnaire is one of the highest-value accuracy checks in the entire access workflow.
Fraud & Abuse: The Legal Backbone
CMS compliance training rests on two anchor federal laws that access staff should recognize by name even without memorizing statutory detail:
- The False Claims Act prohibits knowingly submitting (or causing the submission of) false or fraudulent claims for payment to federal programs like Medicare and Medicaid — this is why accurate registration data and honest documentation matter even before a claim is coded.
- The Anti-Kickback Statute prohibits offering, paying, soliciting, or receiving anything of value to induce referrals for services reimbursable by federal healthcare programs.
Both laws are enforced with the Office of Inspector General (OIG) playing a central investigative role, and both underscore why patient access work — capturing accurate orders, insurance information, and medical necessity documentation — is treated as a compliance function, not just an administrative one.
A physician orders inpatient admission, but the utilization review team determines outpatient observation is appropriate. The patient is still in the hospital. What allows the status to be corrected?
