ACA (Obamacare) Marketplace Appeal Rights
If you buy insurance on the ACA marketplace (healthcare.gov or your state exchange), your appeal rights are different from employer-based insurance. Stronger in some ways, more complex in others.
Good news: ACA plans must offer appeals. Denials aren't final.
Important: Some state exchanges have different rules than federal marketplace. California, New York, and Massachusetts have particularly strong protections.
Three Levels of ACA Appeals
Internal Appeal to Your Insurance Plan (30-45 Days)
Who decides: Your insurance plan's medical review department
Timeline: Insurer has 30 days (standard) or 72 hours (expedited for urgent care)
Success rate: 15-25% (same as employer plans)
How to file: Request in writing within 180 days of denial. Send to appeals department address on your EOB.
External Review by Independent Reviewer (30-60 Days)
Who decides: Independent physician outside your plan
Timeline: 30 days standard, 72 hours expedited
Success rate: 40-60% (higher than internal appeal)
Cost to you: Free (plan pays)
How to file: After internal appeal is denied. Usually request through your state insurance commissioner's office.
Complaint to State Insurance Commissioner (Ongoing)
Who decides: Your state's insurance regulator
Timeline: Varies by state, 30-120 days
Cost to you: Free
What it does: Creates regulatory pressure. May not overturn denial but can force plan to follow rules or impose penalties.
ACA plans: Must have external review process (federally mandated). State insurance commissioners have strong oversight. Plans must clearly explain appeals process.
Employer plans: Also have appeals, but ERISA law is more forgiving to employers. Employer can sometimes self-insure and avoid some regulations. See our general appeal guide for employer plan specifics.
Bottom line: ACA marketplace plans usually have stronger appeals protections than you'd think.
State-by-State ACA Appeal Timelines
All states follow the federal minimum (30 days standard, 72 hours expedited). Some states have stronger requirements:
| State | Standard Appeal Timeline | Expedited Appeal |
| California | 30 days | 72 hours |
| New York | 30 days | 48 hours (STRONG protection) |
| Massachusetts | 30 days | 48 hours |
| Texas | 30 days | 72 hours |
| Florida | 30 days | 72 hours |
| All Other States | 30 days (federal minimum) | 72 hours (federal minimum) |
Check your state insurance commissioner's website for specific rules. Some states have even stronger protections.
How to File an ACA Appeal (Step-by-Step)
Step 1: Request Internal Appeal
Contact your plan (call or email). Request internal appeal for denied claim. Get:
- Appeals address (must be different from claims address)
- Deadline (usually 180 days from denial)
- Confirmation in writing that appeal was received
Step 2: Prepare Appeal Package
Same as employer plans: physician's letter, clinical evidence, guidelines supporting treatment, documented failed conservative care.
Step 3: If Denied, Request External Review
Your plan will include info on how to request external review. If not, contact your state insurance commissioner's office:
- Find your state commissioner: Google "[Your State] Insurance Commissioner" + appeal rights
- File external review request with your denial letter and appeal materials
- Get confirmation in writing that external review was initiated
Step 4: File State Complaint if Needed
If external review fails or you believe your plan violated appeals rules:
- File complaint with state insurance commissioner
- State will investigate and may impose penalties on plan
- May pressure plan into reconsideration
ACA-Specific Appeal Issues
Dispute: "This drug/service isn't covered in my plan"
Your recourse: ACA plans must cover essential health benefits. If your plan denies something that's essential (surgery, imaging, medications for serious conditions), appeal and cite ACA essential health benefits requirement. Often wins on appeal.
Issue: Prior Authorization Denied
Your recourse: Same as employer plans. Request expedited review (72 hours) if urgent. Peer-to-peer review often overturns denials.
Issue: Plan Excluded Your Doctor
Your recourse: ACA plans have network adequacy requirements. If no in-network doctors are available in your area, you may get out-of-network care covered at in-network rates. Appeal to your state insurance commissioner if plan refuses.
Key ACA Appeal Rights You Should Know
- Right to expedited appeal: If medical judgment says delay could jeopardize health, you get 24-72 hour decision (not 30 days)
- Right to written explanation: Plan must explain denial and appeal process in plain language
- Right to external review: Neutral doctor reviews if internal appeal fails
- Right to state oversight: If plan violates appeal rules, state commissioner can investigate and fine the plan
- Right to legal representation: You can hire lawyer to help with appeals (though many don't need one)
If you live in New York, California, or Massachusetts, your state has exceptionally strong ACA appeal protections. Insurers take denials seriously because states enforce heavily. This means your appeals have better chances in these states.
Even in other states, state insurance commissioners can be powerful allies. Filing a complaint with your state often gets results faster than internal appeals. See our full guide on external review options when internal appeals are denied.
