How to Appeal a Health Insurance Denial in Kentucky

Written by Aptiva Health Editorial Team · Reviewed by Taylor Sorrels, Esq. and Crystal Brake, RCM Director · Editorial & review standards · How we research

If your health plan denied care in Kentucky, you have the right to ask for another look. For many plans, you can also ask an independent reviewer who does not work for your insurer.

This guide explains Kentucky’s steps for health insurance appeals and for workers’ compensation. It is part of the Coverage & Appeals Center, which covers the full process for any state.

First: which rules apply to your plan?

Kentucky’s appeal rules apply to state-regulated health plans. These include most individual and family plans and plans that employers buy from an insurance company (fully insured plans). The rules come from Kentucky law (KRS 304.17A-623 and the sections that follow) and a state regulation, 806 KAR 17:290.

Some plans follow federal rules instead:

• Self-funded employer plans (ERISA). Many large employers pay claims themselves. These plans use the federal external review process, not Kentucky’s.
• Medicare and Medicare Advantage. These follow federal Medicare appeal rules (Medicare.gov).
• Medicaid managed care. Kentucky Medicaid has its own appeal and fair hearing steps (907 KAR 17:010).
• Workers’ compensation. Work injuries follow a separate state process, covered below.

Not sure? Ask your HR department or call the number on your insurance card and ask: “Is my plan fully insured or self-funded?”

Kentucky health insurance appeals at a glance

Your denial letter may give a different deadline. Use the earliest date, and confirm it with your plan in writing.

Step 1: The internal appeal

An internal appeal asks your own plan to look at the denial again.

1. Find the reason and the deadline. Read your denial letter. Copy the exact reason. Note the date — most plans must give you at least 180 days, but check your letter (KY DOI UM Review Guide (2026)).
2. Get the plan’s criteria. Ask the plan for the medical policy it used and a copy of your claim file (29 CFR 2560.503-1(h)(2); 45 CFR 147.136(b)).
3. Ask your clinician for help. Request a letter of medical necessity that answers the denial reason.
4. Gather your records. Include visit notes, test results and treatments you already tried.
5. Write and send your appeal. Use the address or portal on the denial letter. Keep proof you sent it.
6. Ask for an expedited review if it’s urgent. The plan generally must decide within 72 hours.
7. Watch for the decision. The plan generally has 30 days for a standard internal appeal.

• Denied as “not medically necessary”
• Denied for missing prior authorization

Step 2: Independent external review

If your plan upholds the denial, you may be able to ask for an independent external review (IER). An independent review organization looks at your case and makes its own decision.

Who can ask

In Kentucky, external review for state-regulated plans covers denials based on medical necessity and on care the plan calls experimental or investigational (KRS 304.17A-600). Some plan-exclusion denials can also qualify after a Department of Insurance review (KRS 304.17A-617).

How to ask

• Ask through your insurer, not directly to the state.
• Your insurer completes form HIPMC-IRE-6; you sign a records release (KY DOI Form HIPMC-IRE-6).
• Ask within 4 months of the final internal denial.

1. Get your final internal denial letter. Note the date. Your 4-month window starts from it.
2. Sign the medical records release. Your insurer, not you, completes form HIPMC-IRE-6 (KRS 304.17A-623).
3. Attach your evidence. Include your clinician’s letter, records and the denial letters.
4. Send it to your insurer. Follow the instructions on your denial letter or the form.
5. Ask for expedited review if urgent. Expedited external review decisions are much faster (KY DOI UM Review Guide (2026)).
6. Keep copies and proof of sending. Track every call with the date and a reference number.

What it may cost

Kentucky charges a one-time $25 filing fee for any external review. It is refunded if you win. It may be waived for financial hardship, such as income under 200% of the federal poverty level. There is a $75 yearly cap (KRS 304.17A-623; 806 KAR 17:290; KY DOI UM Review Guide (2026)).

What happens after

If the independent reviewer sides with you, your plan generally must follow the decision (KRS 304.17A-625). If the reviewer upholds the denial, ask the Department of Insurance about other options.

What happens during the independent review

Once your insurer receives a complete request, the case goes to an independent review organization. Here is what to expect (KRS 304.17A-623; KY DOI IRE Review Guide (2023)).

• Assignment. An independent review organization is assigned to your case.
• Records. Your insurer sends your file. You can usually send more information that supports your case (KRS 304.17A-625).
• Review. A reviewer with relevant clinical training looks at the records and the plan’s criteria (806 KAR 17:290).
• Decision. You and your insurer get the decision in writing, within 45 days at most for a standard review (often sooner), or within 72 hours at most if expedited (KY DOI UM Review Guide (2026)).

Send your strongest evidence up front: your clinician’s letter and the records that answer the denial reason.

A Kentucky appeal, start to finish

*This is an illustrative example, not a real patient. Timelines are for a state-regulated plan.*

• March 1: Alex, who lives in Lexington, gets a letter denying an MRI as “not medically necessary.” Alex marks April 30 on the calendar as a target date, well inside the appeal window in the letter.
• March 4: Alex asks the plan for its imaging policy and asks the clinician’s office for a letter.
• March 18: Alex sends the internal appeal with the clinician’s letter, therapy notes and the policy, by fax. Alex saves the fax confirmation.
• April 15: The plan upholds the denial (within its 30-day window).
• April 20: Alex sends a written external review request and a signed records release to the insurer, well inside the 4-month window.
• Within 45 days at most: The independent reviewer issues a decision (KY DOI UM Review Guide (2026)).

If Alex’s symptoms had been urgent, Alex could have asked for expedited reviews at each step: 72 hours for the internal appeal and within 72 hours at most for external review.

Checklist for your external review request

• Final internal denial letter (copy)
• Signed medical records release (your insurer completes form HIPMC-IRE-6) (806 KAR 17:290)
• Letter of medical necessity from your clinician
• Medical records that answer the denial reason
• The plan’s medical policy with the criteria you meet marked
• Your internal appeal letter (copy)
• Proof of sending, kept for your records

Common mistakes in Kentucky appeals

• Missing the internal appeal deadline. Most plans must allow at least 180 days, but check your letter and file early.
• Sending the external review request to the state. In Kentucky you request it through your insurer.
• Using the state process for a self-funded plan. Self-funded employer plans use the federal process.
• Assuming workers’ comp follows health insurance rules. It doesn’t. Work injuries have their own ladder.

Self-funded employer plans in Kentucky

If your employer’s plan is self-funded, Kentucky’s external review process does not apply. Self-funded plans use the federal external review process. Under the federal rule, you generally have 180 days for an internal appeal and 4 months after a final internal denial to ask for external review (29 CFR 2560.503-1(h)(3)(i); 29 CFR 2590.715-2719). Your plan documents explain the steps.

Who to call in Kentucky

The Department of Insurance can answer questions about state-regulated plans and take complaints. It does not regulate self-funded employer plans (KY DOI Health Insurance Fact Sheet).

Workers’ compensation appeals in Kentucky

If you were hurt at work, your medical care and wage benefits usually go through workers’ compensation, not your health plan. Kentucky’s process is run by the Department of Workers’ Claims. Since April 9, 2026, it has been an independent department attached to the Office of the Governor. It is no longer part of the Education and Labor Cabinet (SB 343, 2026 Ky. Acts ch. 61).

The Kentucky workers’ comp ladder

The Board publishes an appeals handbook (see Sources).

For now, the Department’s web pages are still on the Education and Labor Cabinet’s website (elc.ky.gov).

Workers’ comp disputes can be complex. Many people get legal advice. This page is not legal advice.

Car crash injuries in Kentucky

Kentucky has personal injury protection (PIP), sometimes called no-fault coverage. Your auto policy may pay for medical care before your health plan does.

Tips that help Kentucky appeals succeed

• Respond to the exact reason on the letter. Don’t argue about other things.
• Send the plan’s own criteria with the parts you meet marked.
• Get your clinician’s letter. It carries the most weight.
• Track every deadline with a reminder a week early.
• Keep a call log: date, name, reference number.
• Ask for expedited review when waiting could harm your health.
