OB Doctor Not Covered by New Insurance During Pregnancy

You switched jobs, hit open enrollment, or got a Medicaid redetermination notice — and now you've discovered your obstetrician isn't covered by your new health plan. You're already weeks or months into a pregnancy, you have a relationship with your provider, and the last thing you need is to start over with someone new or face a massive out-of-network bill. This article explains what legal protections you have, exactly how to request continuity of care from your new insurer, and what to do if they say no.

What "Continuity of Care" Actually Means

Continuity of care is a protection that requires your new health plan to let you keep seeing an out-of-network provider at in-network cost-sharing rates — at least temporarily — when you're already in the middle of treatment. For pregnant patients, federal rules under the Affordable Care Act (ACA) treat ongoing pregnancy as active treatment, which means you have a legal basis to ask your new insurer to cover your existing OB at the same cost as an in-network doctor.

This protection exists under ACA Section 2719A, which applies to most employer-sponsored plans and individual marketplace plans. It is not a blank check — it covers a transition period, typically 90 days, or through a "natural endpoint" of care. For pregnancy, delivery is generally considered that natural endpoint, which is a meaningful distinction: many plans and states interpret this to mean your coverage should extend through your postpartum visit, not just to the moment you deliver.

If your coverage changed because your employer switched plans mid-year, see our guide on your rights when your employer changes health insurance plans for additional context on what your employer is required to tell you.

Do Federal Rules Guarantee You Can Keep Your OB?

Federal rules give you the right to request continuity of care and require that insurers have a process to grant it — but they do not automatically guarantee in-network rates for every out-of-network provider in every situation. What they do guarantee is that you have a formal pathway to ask, and that your insurer must respond to that request.

The CMS transitional care rules require that new health plans notify enrollees about continuity of care rights and have a process for transition of care requests. If your new plan is an ACA-compliant plan — which includes most job-based plans and all marketplace plans — it must follow these rules.

There are some exceptions. Grandfathered health plans (plans that existed before the ACA and haven't made major changes) may not be subject to these rules. Short-term health plans are also generally exempt. If you're not sure what type of plan you have, call member services and ask directly: "Is this plan ACA-compliant and subject to continuity of care requirements under Section 2719A?"

What State Laws Add (and Why They Matter More Than Federal Rules)

State laws often go further than federal requirements, and for pregnancy specifically, many states mandate continuity of care through the full course of pregnancy and delivery regardless of network status. This means that in some states, your insurer must cover your OB at in-network rates for your entire pregnancy — not just a 90-day window.

States with strong continuity of care laws for pregnancy include California, New York, Illinois, and Texas, among others — but the specifics vary. Some states require coverage through delivery plus a postpartum period. Others require it only if your OB is willing to accept the in-network rate. To find your state's exact rule, go to your state insurance commissioner's website. The National Association of Insurance Commissioners (NAIC) maintains a directory of all state regulators at naic.org.

Why does this matter practically? If your state law is stronger than the federal baseline, your insurer must follow the state law. When you make your continuity of care request, you can — and should — cite both the federal ACA requirement and your specific state statute if your state has one.

How to Request Continuity of Care: Step by Step

Do not simply call and ask for an "out-of-network exception." That is a different process and has a lower standard of review. Use the specific language: "I am requesting a continuity of care or transition of care authorization." Here is exactly how to proceed.

Step 1: Gather Your Documentation

Before you call or write, collect the following:

• Your OB's full name, practice name, and NPI number (National Provider Identifier — a unique 10-digit number every licensed provider has; you can look it up at npiregistry.cms.hhs.gov)
• Documentation of your current pregnancy and gestational age — a recent visit summary or letter from your OB works well
• A written statement from your OB confirming you are an active patient and that disruption of care would be medically inadvisable
• Your new insurance card and member ID
• The date your old coverage ended and your new coverage began

Step 2: Submit a Written Request to Your New Insurer

Call member services to get the correct fax number or mailing address for continuity of care requests — not the general correspondence address. Then send a written request that includes your documentation. Ask for written confirmation that your request was received, and write down the name of every person you speak to and the date. Email is preferable to mail if the insurer accepts it, because you have a timestamp.

Step 3: Get Your OB's Office Involved

Ask your OB's billing department to contact the new insurer directly. They do this regularly and know the language. They can also confirm whether your OB is willing to accept the in-network rate as a condition of the continuity of care agreement — some state laws require your provider to agree to this as part of the arrangement.

A Concrete Example

Sarah is 22 weeks pregnant when her husband's employer switches from Plan A to Plan B on October 1. Her OB is not in Plan B's network. Under their state's continuity of care law, Sarah has the right to keep her OB at in-network rates through 60 days postpartum. Without the protection, her OB visits would be billed at 40% coinsurance out-of-network instead of a $30 copay in-network — and her delivery, which would cost the plan roughly $15,000, would be subject to a separate out-of-network deductible of $4,000 instead of her in-network deductible of $1,500. Sarah submits a written continuity of care request on October 3 with her OB's letter, her pregnancy documentation, and her OB's NPI. The insurer approves within 10 days and issues a letter confirming in-network cost-sharing through delivery and her six-week postpartum visit.

What to Do If the Insurer Denies the Request

A denial is not the end. You have several tools available, and using more than one simultaneously is both allowed and often effective.

File an Expedited Internal Appeal

Federal law gives you the right to an expedited internal appeal when a standard timeline — typically 30 days — would seriously jeopardize your health. Pregnancy qualifies. An expedited appeal must be resolved within 72 hours. When you file, state explicitly: "I am requesting expedited review because I am pregnant and a delay in accessing prenatal care poses a serious health risk." See our full guide to appealing a denied insurance claim for the complete process.

Request External Independent Review

If your internal appeal fails, you have the right to external independent review — a review by an organization that has no financial relationship with your insurer. This right applies to all ACA-compliant plans. The reviewer's decision is binding on the insurer. Your denial letter is required by law to include instructions on how to request external review.

File a Complaint With Your State Insurance Commissioner

This is often the fastest path to resolution, and many people skip it when they shouldn't. Filing a formal complaint with your state insurance commissioner creates a record and requires the insurer to respond to a regulator — which often prompts faster reconsideration than the formal appeal process alone. File online through your state commissioner's website. You can file a complaint and pursue an appeal at the same time.

If Your Hospital Is Also Going Out of Network

Sometimes the issue isn't just the OB — it's the hospital where they deliver. If that's the case, read our guide on what to do when your hospital is leaving your insurance network, which covers the same continuity of care framework applied to facility coverage.

What If You Simply Can't Keep Your OB?

If every avenue fails and you genuinely need to switch providers, ask your current OB for a formal referral and a complete copy of your medical records — including all prenatal labs, ultrasound reports, genetic screening results, and your current care plan. You are legally entitled to these records. Finding a new in-network OB who accepts patients at your gestational age can be challenging; our guide on what to do when doctors won't accept your insurance walks through how to search effectively and what to say when you call.

What to Do Right Now

If you just found out your OB isn't covered, start today — not after your next appointment. Call your new insurer's member services line and use the words "continuity of care request" or "transition of care request." Get your OB's office on the phone the same day to request their support letter and NPI. Submit everything in writing. If you're in a state with strong continuity of care protections, cite your state law by name when you make the request. And if the insurer denies you, file an expedited appeal and a state insurance complaint at the same time. You have rights here — you just need to invoke them explicitly and in writing.
