Self-Employed? Insurance Claim Denied? Your Solo Policy Rights

Self-employed individuals — freelancers, independent contractors, sole proprietors, and small business owners — purchase their own health insurance and face claim denials without institutional support. Without an HR department or union to help navigate disputes, a claim denial can feel both financially devastating and procedurally overwhelming. The good news: the legal framework governing individual market health insurance is strong, and self-employed people actually benefit from regulatory protections that ERISA-governed employees do not have access to.

Why Insurers Deny Self-Employed People's Claims

Medical necessity determinations using criteria more restrictive than clinical standards. Utilization reviewers apply standardized clinical criteria (InterQual, Milliman, or insurer-proprietary policies) to ACA marketplace and individual market plans. Under 45 CFR § 147.136(b)(3), these criteria must reflect generally accepted standards of medical practice. When they do not — when the insurer's threshold is higher than what specialty medical societies recommend — the criteria themselves are challengeable.

Prior Authorization Denied: How to Appeal" class="auto-link">Prior authorization not obtained. ACA individual plans require prior authorization for many services, particularly specialty medications, imaging, and elective procedures. Missing or expired authorization is a procedural denial that can sometimes be reversed by demonstrating that authorization was not properly communicated as a requirement, or by showing the treatment was emergent.

Essential health benefit exclusions. ACA-compliant plans must cover ten categories of essential health benefits under 45 CFR § 147.126. Denials that effectively exclude a service within these categories — such as mental health, prescription drugs, rehabilitative services, or preventive care — are legally vulnerable.

ERISA does not apply, which is an advantage. Individual market plans are not governed by the Employee Retirement Income Security Act of 1974 (29 U.S.C. § 1001 et seq.). ERISA preempts state insurance laws and limits litigation remedies for employer-plan participants. Without ERISA, your state insurance commissioner has full jurisdiction, state insurance laws apply, and if your insurer acts in bad faith, state court remedies — including consequential and punitive damages — may be available.

QSEHRA and HRA disputes have a separate resolution path. If your small employer provides a Qualified Small Employer Health Reimbursement Arrangement (QSEHRA), disputes over whether a submitted expense qualifies for reimbursement are separate from your underlying insurance claim denial. QSEHRA administration disputes are governed by IRS rules (Publication 969 and IRS Notice 2017-67), not state insurance law.

How to Appeal a Denied Claim on Your Solo Plan

Step 1: Confirm Your Coverage Framework

Verify whether your plan is an ACA-compliant marketplace plan, an ACA-compliant off-exchange plan, a short-term plan, or a health sharing ministry arrangement. Only ACA-compliant plans carry the full suite of internal and external appeal rights under 45 CFR §§ 147.136 and 147.138. Short-term plans and health sharing ministries are not required to comply with these regulations.

Step 2: Obtain the Full Denial in Writing

Request the written denial specifying the exact reason, the clinical criterion or policy provision applied, and your appeal rights including deadlines. Also request the complete claims file and any clinical policy bulletins used in the review. You cannot write an effective appeal without knowing precisely what you are rebutting.

Step 3: Get Your Physician's Support

A letter of medical necessity from your treating physician is the most effective piece of evidence in any individual market appeal. The letter should document your diagnosis, the clinical rationale for the treatment, why alternatives were inadequate or inapplicable, applicable clinical guidelines from the relevant specialty society, and why the treatment meets the medical necessity standard.

Step 4: Submit the Internal Appeal Within the Deadline

File a written appeal within the deadline on your denial notice — typically 180 days for standard claims. The insurer must decide within 30 days for prospective denials and 60 days for post-service claims, with a 72-hour expedited review available for urgent situations. Your appeal letter should address each denial reason specifically, cite the clinical evidence and applicable plan terms, and include your physician's supporting letter.

Step 5: File for External Independent Review: Complete Guide" class="auto-link">External Review After Internal Exhaustion

Under 45 CFR § 147.138, external review by an IROs) Explained" class="auto-link">Independent Review Organization is available after internal appeal exhaustion. The IRO's decision is binding on your insurer. You typically have four months from the final internal appeal denial to file. External review success rates run 40 to 60 percent for overturned denials in published studies.

Step 6: File a State Insurance Department Complaint

File simultaneously with your external review request. Your state insurance commissioner has full regulatory authority over individual market insurers — a stronger oversight relationship than exists for ERISA-governed employer plans. State regulators can investigate, order claim reversals, and impose fines. A formal complaint also creates a regulatory record that supports any subsequent legal action.

What to Include in Your Appeal

• Denial letter identifying the specific policy provision and clinical criterion cited
• Your physician's letter of medical necessity with clinical guidelines cited
• Your plan's Summary of Benefits and Coverage showing the relevant coverage terms
• Documentation of prior treatments tried and outcomes, demonstrating step therapy exhaustion
• Clinical guidelines from the relevant specialty society showing the treatment meets accepted standards
• Evidence of any ACA regulatory violations applicable to your situation
• For QSEHRA disputes: separate correspondence to the employer/plan administrator citing applicable IRS rules
