Why Insurers Deny Claims in New Hampshire

UHC applies proprietary Optum/InterQual clinical criteria when evaluating medical necessity — internal standards that may be more restrictive than guidelines from recognized medical societies. UHC's reviewers typically evaluate claims without direct knowledge of your condition or clinical history. The most common denial reasons New Hampshire members encounter include:

• Medical necessity disputes — UHC's internal reviewer determined your treatment does not meet its Optum/InterQual clinical criteria
• Prior Authorization Denied: How to Appeal" class="auto-link">Prior authorization not obtained — The service required pre-approval that was not secured before treatment
• Out-of-network provider — Your provider is outside UHC's New Hampshire network
• Service excluded from plan — The treatment is listed as a plan exclusion
• Step therapy not satisfied — UHC requires trying a less expensive alternative first
• Insufficient documentation — Clinical records submitted do not satisfy UHC's documentation requirements
• Filing deadline missed — The claim was submitted after UHC's timely filing window

Your denial letter must specify the exact denial reason. If it does not, contact UHC and request the complete denial rationale and the clinical policy bulletin used in the review — this is your right under ERISA and ACA regulations.

How to Appeal a UnitedHealthcare Denial in New Hampshire

Step 1: Review the Denial Letter and Mark Your Deadline

Read your denial letter carefully. It must include the specific reason for denial, the policy provision or clinical criteria applied, your appeal rights, and the filing deadline. For commercial plans, the internal appeal deadline is 180 days from the denial date. For Medicare Advantage plans, it is 60 days. Mark this deadline immediately. Under ERISA (29 CFR 2560.503-1), request the full claims file and the UHC clinical policy bulletin within days of receiving the denial.

Step 2: Build a Complete Evidence Package

Strong documentation is the cornerstone of a successful appeal. Before drafting your letter, collect:

1. Your denial letter with the exact denial reason and policy citation
2. Complete medical records documenting your diagnosis and treatment history
3. A detailed letter from your treating physician addressing UHC's specific denial criteria
4. Clinical practice guidelines from relevant medical organizations confirming your treatment is standard of care
5. UHC's clinical policy bulletin — identify where your clinical situation meets or exceeds each listed criterion

Step 3: Write a Targeted Appeal Letter

Open with your UHC member ID, claim number, and denial date. Address each denial reason systematically using specific clinical evidence. Attach your physician's medical necessity letter. Cite the ACA (45 CFR 147.136 for appeal rights), ERISA (29 CFR 2560.503-1 for claims procedures), Mental Health Parity Act (MHPAEA) Explained" class="auto-link">MHPAEA if mental health or substance use coverage is involved, and the No Surprises Act if out-of-network billing is at issue. Reference New Hampshire Insurance Department regulations on timely and fair claims handling where applicable.

Step 4: Submit and Document Everything

Send your appeal via certified mail to the UHC Appeals address on your denial letter and through the UHC member portal at uhc.com. Keep copies of all documents and delivery confirmations. Log every phone call with UHC — date, time, representative name, and what was discussed. UHC must respond within 30 days for standard internal appeals and 72 hours for urgent cases.

Step 5: Request Peer-to-Peer Review

Ask your treating physician to request a peer-to-peer call with UHC's medical director. Direct clinician-to-clinician discussion of your case frequently resolves medical necessity disputes more quickly than written appeals alone.

Step 6: Escalate If the Internal Appeal Fails

If UHC upholds the denial after internal review:

• External review — File for independent review through the New Hampshire Insurance Department. An IRO evaluates your case and its decision is binding on UHC.
• Regulatory complaint — File at https://www.nh.gov/insurance/ or call (603) 271-2261. A formal complaint creates regulatory pressure and a paper trail.
• Legal action — For high-value denials, consult an insurance appeal attorney about ERISA Section 502(a) claims or New Hampshire state law remedies.

What to Include in Your Appeal

A thorough appeal package maximizes your reversal odds:

• Your UHC denial letter with the specific denial reason and policy citation highlighted
• Physician's medical necessity letter using clinical language that directly addresses UHC's denial criteria
• Medical records — diagnosis documentation, test results, treatment history, and records of prior treatments tried
• Clinical guideline citations from recognized medical societies confirming your treatment as standard of care
• Legal citations — ACA 45 CFR 147.136, ERISA 29 CFR 2560.503-1, and New Hampshire Insurance Department regulations on fair claims handling
