Insurance, Prior Authorizations & Step Therapy

Insurance rules shape how quickly people with inflammatory bowel disease (IBD) can start or keep needed treatments. Prior authorizations and step therapy can cause delays but can also be navigated with planning and support. This article explains how these processes work in the United States and highlights practical advocacy tools and organizations that help patients and families.

Key Takeaways

• Prior authorization is insurer approval that may be required before an IBD test, procedure, or medicine is covered. (healthcare.gov)

• Step therapy (fail first) means trying insurer‑preferred, usually lower‑cost drugs before the originally prescribed option is covered. (accc-cancer.org)

• If coverage is denied, most health plans must offer an internal appeal and, in many cases, an independent external review. (healthcare.gov)

• Strong medical notes from the IBD team and careful record‑keeping often make the difference in prior authorization and step therapy decisions. (crohnscolitisfoundation.org)

• National groups such as the Crohn’s & Colitis Foundation and Patient Advocate Foundation provide free tools and case managers to help with insurance problems. (crohnscolitisfoundation.org)

How insurance decisions affect IBD care

IBD care often involves advanced medicines, frequent lab tests, scopes, and imaging. Insurers use rules like prior authorization and step therapy to decide what they will pay for and in what order. These rules apply across many plan types, including employer plans, Affordable Care Act Marketplace plans, Medicare Advantage, and some Medicaid programs. (kff.org)

For a person living with IBD, these processes can delay starting a biologic, getting a colonoscopy approved, or switching from a failing medicine. Understanding the language insurers use, and how decisions can be appealed, helps patients, families, and care teams push for timely, guideline‑based treatment.

Key terms: prior authorization, step therapy, and more

A few core insurance terms show up often in IBD:

• Formulary
  The plan’s approved list of covered prescription drugs, often organized into price “tiers.” (healthinsurance.org)

• Prior authorization (preauthorization, prior approval)
  Written approval from a health plan that may be required before a service or prescription will be covered. (healthcare.gov)

• Step therapy (“fail first”)
  A rule that coverage for a higher‑cost drug only begins after one or more lower‑cost options have been tried and shown not to work or not to be appropriate. (accc-cancer.org)

• Quantity or dose limits
  Caps on how much of a drug a person can receive in a given time period without extra review.

• Explanation of Benefits (EOB)
  A summary from the insurer that explains what was billed, what the plan paid, and what the patient may owe.

Prior authorization: what it is and how it works

Prior authorization lets the insurer review a proposed test, procedure, or medicine in advance and decide if it is “medically necessary” under the plan. (healthcare.gov)

For IBD, prior authorization is common for:

• Biologics and small‑molecule drugs

• Certain imaging, such as MRI or CT enterography

• Hospital stays and many surgeries

Typical steps:

1. The gastroenterologist recommends a treatment or test.

2. The clinic or specialty pharmacy learns that prior authorization is required.

3. Staff submit forms, clinical notes, and sometimes lab or scope reports. (mayoclinic.org)

4. The insurer reviews the request, which can take from a couple of days to several weeks, depending on urgency and plan rules. (mayoclinic.org)

5. The plan issues an approval, denial, or request for more information.

Even a small error, such as a missing code or incomplete documentation, can lead to delay or denial. (crohnscolitisfoundation.org)

Step therapy in IBD

Step therapy is a type of prior authorization that controls which drug is tried first. Insurers may require a patient with IBD to start with a generic immunomodulator, a particular biosimilar, or an older biologic before covering a newer or differently targeted agent. (accc-cancer.org)

This can create problems when:

• A person has already failed the “required” drug in the past.

• National IBD guidelines favor a different first‑line therapy for that disease pattern. (gastro.org)

• Waiting through extra “steps” risks irreversible damage, hospitalization, or surgery.

Many states now have laws that set guardrails on step‑therapy rules, such as clear timelines for decisions and processes for exceptions, although protections vary and often do not reach all types of employer plans. (cambridge.org)

Prior authorization vs step therapy: quick comparison

When coverage is denied: appeals and exceptions

If a prior authorization or step‑therapy request is denied, most U.S. health plans must allow at least one internal appeal, and many must also allow an independent external review. (healthcare.gov)

Important points:

• The denial letter should explain the reason and include instructions and deadlines for appeal.

• Internal appeals usually must be completed within specific time frames, such as 30 days for services not yet received and shorter timelines for urgent situations. (healthcare.gov)

• In emergencies or situations where waiting would seriously harm health, an expedited appeal and external review can be requested. (healthcare.gov)

For step therapy, many states and some proposed federal laws outline when an exception should be granted, for example when a required drug has already failed, is likely to be ineffective, or is contraindicated. (cambridge.org)

Strong, specific letters from the IBD clinician that describe disease severity, past drug history, and the medical risks of delay often improve appeal success. (crohnscolitisfoundation.org)

Practical navigation tips for patients and families

Several habits can make these processes smoother:

• Keeping copies of insurance cards, formularies, denial letters, and prior authorization approvals in one place helps everyone stay organized.

• Recording dates, names, and call summaries with the insurer, pharmacy, and clinic creates a helpful paper trail for appeals. (healthcare.gov)

• Many GI practices have dedicated staff who manage prior authorizations; asking how to reach this team can speed communication. (mayoclinic.org)

• Employer human resources departments sometimes offer benefits navigators who can explain plan rules or escalate urgent problems. (kff.org)

When a denial arrives, common next steps include asking the insurer to clarify the exact reason, confirming whether missing paperwork can be fixed quickly, and having the IBD team begin an appeal or exception request if the decision conflicts with medical need. (crohnscolitisfoundation.org)

Advocacy and support resources

Several organizations focus specifically on IBD and insurance access:

• Crohn’s & Colitis Foundation
  Provides education on prior authorization and step therapy, sample appeal letters, and an IBD Help Center that answers questions about denials and costs. (crohnscolitisfoundation.org)

• Patient Advocate Foundation (PAF)
  Offers free one‑on‑one case management to help secure prior authorizations, appeal denials, and connect patients with financial assistance. PAF hosts the Jennifer Jaff CareLine specifically for people with IBD. (patientadvocate.org)

• Gastroenterology professional societies
  Groups such as the American Gastroenterological Association provide step‑therapy education and advocate for reforms that protect timely access to GI therapies. (gastro.org)

State insurance departments and Consumer Assistance Programs can also guide residents through appeals and help explain state‑specific protections. (doi.wyo.gov)

FAQs

How long does a prior authorization usually last?

Many medication approvals are written for a set period, often around 6 to 12 months, after which a renewal request may be needed, especially for chronic conditions like IBD. The exact duration depends on the health plan’s rules. (mayoclinic.org)

Is prior authorization a guarantee that the insurer will pay?

No. Prior authorization means the service or drug meets the plan’s rules at the time of review, but claims can still be denied later for other reasons, such as loss of coverage or billing errors. (healthcare.gov)

What if treatment cannot safely wait for step therapy?

When delay would likely cause serious harm, the IBD clinician can request a step‑therapy exception and expedited review, explaining why the insurer’s preferred drug is inappropriate. Many state and federal rules support faster decisions in urgent cases. (healthcare.gov)

Who can help if the process feels overwhelming?

Gastroenterology clinics, hospital social workers, employer benefits staff, the Crohn’s & Colitis Foundation’s IBD Help Center, and Patient Advocate Foundation case managers all assist with denials, appeals, and cost‑of‑care questions. (crohnscolitisfoundation.org)
