What Should You Do When an Insurer Says a Claim Is Still Under Review?

When a health insurer says a claim is “under review,” ask what review is happening, what information is missing, who must supply it, and when a written decision is expected. Keep the claim number and every response. A vague status is not a final denial, but it is not proof that payment is on the way either.

Identify the actual stage

A claim can be received but not adjudicated, suspended for missing documentation, rejected before processing, or formally denied. These states require different responses. Ask whether the claim passed initial intake, whether it has an assigned processing number, and whether a request for records is outstanding. A provider’s clearinghouse acceptance report does not by itself prove the payer accepted the claim for adjudication. Ask for the payer’s own receipt date and tracking identifier.

Ask questions that produce a record

Use precise language: “Please identify the claim number, date received, current processing status, any outstanding documentation request, the party responsible for responding, and the expected date of a written determination.” Ask the representative to read back the information and provide a call reference number. If the insurer cannot provide an estimated date, request the published claim-processing policy or the applicable plan document rather than accepting an invented deadline.

Separate the patient’s and provider’s roles

Patients can request an explanation of benefits, contact member services, and ask whether an authorization or eligibility problem is involved. Billing staff can check payer acknowledgments, remittance files, medical-record requests, coordination-of-benefits data, and the original submission format. Neither should assume that the other received every letter. A patient can authorize appropriate sharing of records without sending unnecessary sensitive details through unsecured channels.

Check the applicable time requirements

Payment and appeal rules depend on the plan, payer, jurisdiction, and type of claim. Employer plans, marketplace coverage, Medicare, Medicaid, and other government programs do not share one universal clock. For an employer-sponsored plan, consult the plan’s claims procedures and the U.S. Department of Labor’s guidance. For Medicare coverage disputes, identify whether the issue involves Original Medicare or a Medicare Advantage plan. Ask which rule governs this particular claim and get the answer in writing.

Escalate the unresolved status

If promised follow-up does not arrive, send a dated written inquiry through the plan’s documented channel, attach only necessary identifiers, and retain proof of submission. Ask for a supervisor or claims resolution unit when repeated calls produce inconsistent answers. If a denial appears, switch to the applicable formal appeal process rather than continuing informal calls. An urgent treatment decision may require an expedited review; ask the treating clinician and plan about the correct process.

Protect yourself from billing confusion

Do not equate “under review” with “you owe the balance.” Request an itemized bill and explanation of benefits, confirm whether the provider is in-network, and ask the provider to note that coverage remains unresolved. Preserve collection notices and dates. Do not ignore a genuine billing deadline, but do not pay solely because a phone representative described an unresolved claim as denied.

A simple tracking example

A practical log might read: September 10, 9:20 a.m.; payer member services; claim 1234; received August 24; pending operative report from clinic; representative reference 5678; clinic notified the same day; follow-up scheduled September 15. This is an illustrative format, not a real case. Its value is that every next step has an owner and a date.

Frequently asked questions

Does “pending” mean denied? No; it may mean no final determination has been made. Can a provider resubmit immediately? Not always: an unnecessary duplicate can complicate processing, so first identify the payer’s instructions. Is an oral assurance enough? No; request a written decision or documented status whenever possible.
