ACA appeal rights — the federal floor

What the ACA actually guarantees

Section 2719 of the Public Health Service Act (added by the ACA) and its implementing regulations at 45 CFR 147.136 set a minimum standard for the health-insurance appeal process. The most consumer-facing elements:

• At least 180 days from receipt of an adverse benefit determination to file an internal appeal.
• 30 days for the plan to decide a pre-service internal appeal; 60 days for a post-service appeal.
• 72 hours for the expedited (urgent) decision when waiting could jeopardize the consumer’s health or ability to regain maximum function.
• “Full and fair review” — the appeal must be decided by someone not involved in the original denial, with appropriate clinical expertise where a medical judgment is involved. The plan must share any new evidence before deciding.
• Free access to the claim file on request, including internal guidelines and reviewer credentials.
• External review by a certified Independent Review Organization after the internal appeal, with at least 4 months to request it; decisions are binding on the plan.
• Standardised content for denial notices — the specific reasons, the plan provisions relied on, the criteria used, and a description of how to request external review.

“The ACA does not give you the right to a particular outcome. It gives you the right to a process — a meaningful internal review followed by an independent external review that is binding on the insurer.”

Which plans are covered

The ACA appeal rules apply to most non-grandfathered plans, including:

• Individual and family plans bought through the ACA Marketplaces (HealthCare.gov and state exchanges).
• Individual and family plans bought off-Marketplace.
• Most non-grandfathered employer-sponsored group plans, both fully-insured and self-funded.
• Student health plans that meet the definition of a group plan.

For self-funded employer plans the analogous federal claims regulations at 29 CFR 2560.503-1 (the ERISA claims-procedure rules) cover the same ground; the substantive protections are very similar. The ERISA appeals guide walks through the self-funded specifics.

Which plans are not covered

Several coverage types are exempt from the ACA appeal rules or subject to a separate regime:

• Grandfathered plans. Plans that have been continuously in place since March 23, 2010, with limited changes, are exempt from many ACA requirements including the appeal rules. Grandfathered plans must disclose their status; if you see “grandfathered” on your plan documents, you may have fewer federal appeal rights and may need to look to state law.
• Short-term limited-duration plans, fixed-indemnity plans, accident-only plans, and similar non-comprehensive coverage often are not subject to the ACA at all.
• Medicare and Medicaid have their own appeal regimes (Medicare Advantage organisations follow CMS regulations; Medicaid follows fair-hearing rules).
• Retiree-only plans and certain church plans may be exempt.

The timeline grid

The federal floor in a single view:

1. Initial adverse determination. The denial notice arrives. The clock starts.
2. Up to 180 days to file the internal appeal. Calendar the deadline the day you read the letter. Some plans are more generous; none can give you less.
3. Internal appeal decision. 30 days for pre-service; 60 days for post-service; 72 hours for expedited. The decision letter must give specific reasons and an external-review pathway.
4. External review request. At least 4 months from the final internal denial. Many state programs are more generous.
5. External review decision. 60 days for standard; 72 hours for expedited. Binding on the plan.

What the federal floor doesn’t guarantee

The ACA appeal rules are a procedural floor. They do not change what your plan covers. A few common misconceptions worth naming:

• The ACA does not guarantee coverage for any specific service outside the Essential Health Benefits categories. A plan exclusion can still defeat an appeal on the merits.
• The ACA does not let you appeal a clear plan exclusion externally. External review generally applies to medical- necessity, appropriateness, level-of-care, experimental, and rescission disputes — not to disputes about whether a service is covered by the plan’s written terms at all.
• The ACA does not give you a private right of action for damages. The remedy is the appeal and external review process. For self-funded ERISA plans, ERISA Section 502 governs litigation, on a deferential record-based standard.
• State law may give you additional protections — Mental Health Parity enforcement, surprise-billing laws, fertility mandates, autism mandates. The ACA floor is in addition to, not in place of, those state protections.

Using the federal floor in an appeal

A few practical uses of the ACA appeal rights in the letter itself:

• When the denial letter omits the specific reasons or the plan-language citation, point to 45 CFR 147.136 and request the records the regulation requires. The plan must produce them free of charge.
• When the appeal reviewer lacks the clinical specialty relevant to the dispute, flag the “full and fair review” requirement.
• When the case is time-sensitive, request expedited internal appeal and external review simultaneously — both must be decided within 72 hours.
• When the plan misses an internal-appeal deadline, the consumer is generally deemed to have exhausted internal remedies and can proceed directly to external review.

Where InsureDefense fits

We prepare appeals that engage with the federal floor and any applicable state law. The base appeal package frames the internal appeal; our External Review Pack prepares the state or HHS-administered external review request after an internal denial.
