How to appeal a denied scleral lens claim

A denial isn't always the end. Many are fixable: a missing test result, the wrong benefit, a criterion nobody addressed. Here is how the appeal process works for most private plans, what to send, and how Medicare differs.

The short answer

Start by finding out exactly why the claim or prior authorization was denied. For most private health plans you can then file an internal appeal within 180 days of the denial notice, with a letter from your fitter and the records that answer the reason given. If the plan still says no, you can usually ask for an independent external review. Medicare and some other plan types have their own processes, so check your denial letter.

Key points

  • Read the denial reason first: it tells you what the appeal must answer.
  • Internal appeal: ask the plan to reconsider, usually within 180 days.
  • External review: an independent reviewer decides, and the plan must accept the result.
  • Your fitter's letter and test results are the core of the appeal.
  • Keep copies and notes of every call.

You have the right to appeal

If your health insurer refuses to pay a claim, it has to tell you why and how you can dispute the decision. HealthCare.gov describes two levels:[1]

  • Internal appeal: you ask the insurance company to conduct a full and fair review of its own decision.
  • External review: an independent third party reviews the decision, so the insurer no longer gets the final say.

This page follows the federal process HealthCare.gov describes for health insurers. Vision plans, Medicare, Medicaid, and some employer plans have their own processes. Your denial letter should tell you which applies.

Step 1: Find out exactly why

The reason shapes everything that follows. Common reasons for scleral lens denials include:

  • Not medically necessary under the plan’s criteria. For example, the records didn’t show a required test result. One vision plan’s criteria for keratoconus call for topography, OCT, corneal mapping, or keratometry.[5]
  • Excluded benefit. Some medical plans exclude contact lenses except for narrow uses. Aetna’s policy, for instance, covers scleral lenses used as a bandage for severe ocular surface disease even under plans that exclude contact lenses, but not lenses for keratoconus.[6] A denial might mean the claim belongs under a different plan, or that the diagnosis on the claim didn’t reflect why the lens was prescribed.
  • No prior authorization when one was required.
  • Wrong benefit or code. A claim processed under an elective contact lens benefit instead of a medically necessary one.
  • Out of network with no out-of-network benefit.

If the letter isn’t clear, call the plan and ask what specific information would change the decision.

Step 2: File an internal appeal

For most private health plans, you must file your internal appeal within 180 days (6 months) of receiving the denial notice.[2] To file, you complete the insurer’s forms, or write to the insurer with your name, claim number, and insurance ID number. You can submit any additional information you want considered, such as a letter from your doctor.[2]

For a scleral lens appeal, that usually means:

  1. Your fitter’s letter of medical necessity, updated to answer the specific reason for the denial, point by point against the plan’s criteria.
  2. Supporting records: topography or other test results, vision measurements with glasses and with lenses, and notes on other lenses and treatments already tried.
  3. The plan’s own policy, if a written criterion supports your case.
  4. Your own short letter, if you want, explaining how the condition affects your daily life.

The Consumer Assistance Program in your state can file an appeal for you.[2]

If your situation is urgent, the insurer must speed up the process, and you can ask for an external review at the same time.[1][2]

Step 3: Ask for an external review

If the internal appeal is denied, you can usually request an external review. You must file a written request within 4 months of receiving the final denial.[3] External review covers denials involving medical judgment where you or your provider disagree with the plan, among others. The reviewer either upholds the insurer’s decision or decides in your favor, and the insurer is required by law to accept the decision.[3]

Standard external reviews are decided no later than 45 days after the request is received; expedited reviews, no later than 72 hours.[3] Your explanation of benefits or final denial letter gives the contact for the organization that handles your external review.[3]

If you have Original Medicare

Medicare has its own appeals process. One point matters before care starts: if a provider gives you an Advance Beneficiary Notice of Non-coverage, the option you choose affects your appeal rights. If you choose to receive the item and have a claim submitted, you can appeal if Medicare denies it. If you ask that no claim be sent to Medicare, you can’t appeal.[4]

What to ask

Your plan:

  1. What is the specific reason for the denial, and which policy or criterion was applied?
  2. What information would change the decision?
  3. What’s my deadline for an internal appeal, and where do I send it?
  4. Can my doctor file for me? Is there a form?
  5. Is there a peer-to-peer option for my doctor to discuss the case with the plan’s reviewer?

Your fitter:

  1. Can you update the letter to address the denial reason?
  2. Which test results support each criterion?
  3. Will you file the appeal, or should I? Is there a fee?

Rules and deadlines vary by plan type and change over time. Your denial letter and plan documents are the final word on the process that applies to you.

Common questions

Is it worth appealing?

If the denial was for missing information, the wrong benefit, or a medical judgment you and your fitter disagree with, often yes. If your plan clearly excludes contact lenses and your situation doesn't fall under an exception, an appeal is less likely to change the outcome, though it can still be worth asking whether another benefit, such as a vision plan, applies.

Can my fitter appeal for me?

Yes, often. You may need to sign a form authorizing them to act for you. Your state's Consumer Assistance Program, if there is one, can also file an appeal for you.

What if my case is urgent?

Tell the plan. For urgent situations, plans must speed up the internal appeal, and you can ask for an external review at the same time.

My plan is through my employer. Do the same rules apply?

The details can depend on the type of plan. Insurers have to tell you how you can dispute a decision, so check your denial letter and plan documents for the process and deadlines that apply to you, and ask your plan or HR department if anything is unclear.

The letter of medical necessity for scleral lenses

It's a signed letter from your eye doctor explaining your diagnosis, the test results that support it, what you've already tried, and why scleral lenses are needed. Plans that publish their requirements ask for the specific indication, supporting history, exam and test results, and the lens prescription. Your fitter writes and signs it; you can help by getting your plan's written criteria and your old records to the office.

Prior authorization for scleral lenses

Prior authorization is your plan agreeing in advance that a service or item is medically necessary. Many plans require it for medically necessary contact lenses; your fitter's office usually submits it with your records. Approval isn't a promise to pay: the claim can still be limited by your benefits, deductible, and network. Ask both your plan and the practice whether it's needed before any lenses are ordered.

What counts as medically necessary contact lenses?

It means lenses needed to treat or see with a qualifying eye condition, where glasses don't do the job. Plans that publish criteria commonly list keratoconus and other irregular corneas, very high prescriptions, a large difference between the eyes, missing natural lens or iris, and severe ocular surface disease. Each plan sets its own conditions, measurements, and paperwork, and meeting the criteria doesn't guarantee approval. Ask your plan for its written criteria.

Does Medicare cover scleral lenses?

Original Medicare doesn't usually cover contact lenses, including scleral lenses used to correct vision for conditions like keratoconus. The exceptions are narrow: lenses after cataract surgery or for an eye without its natural lens, and, in rare cases, a scleral lens used as a prosthetic to protect an eye with severe dry eye. Medicare Advantage plans may add vision benefits. Ask your plan and confirm the practice is a Medicare-enrolled supplier.
