What are the statutory grounds to override step therapy for GLP-1s?

The five standard statutory exception grounds are: 1) Contraindication to the required drug, 2) Documented severe adverse reaction, 3) Previous trial and failure, 4) Expected ineffectiveness, and 5) Clinical stability on the requested GLP-1.

Overriding step therapy for GLP-1 medications

Insurance plans often demand you "fail first" on older, cheaper drugs (metformin, phentermine, or older GLP-1s) before approving Zepbound or Wegovy. State laws and ERISA regulations provide clear statutory grounds for an immediate override.

The Strategy in One Minute

Insurance plans often demand you "fail first" on older, cheaper drugs before approving newer GLP-1s. But over 35 state statutes and ERISA rules provide clear legal grounds to bypass step therapy through an immediate physician exception.

Standard Rule: Fail-First Mandate (Blocked / Delayed)
PBMs demand trial and failure on 1 to 3 older medications (such as phentermine or metformin) before approving Zepbound or Wegovy.

Statutory Override: Clinical Exception (Direct Approval)
Physician attests contraindication, past intolerance, or stable therapy. Overrides fail-first mandates with 24–72h decision windows.

The 5 Legal Grounds for a Step Therapy Exception

Under state step-therapy override statutes (enacted in over 35 states) and standard health plan guidelines, a plan must grant an exception if your prescriber certifies one of the following:

1. Contraindication: The required step-1 drug is contraindicated for the patient (e.g. renal impairment, uncontrolled hypertension, history of arrhythmias, or drug interactions).
2. Documented Adverse Reaction: The patient has previously experienced a severe adverse event, physical harm, or intolerable gastrointestinal side effects from the required drug.
3. Previous Trial & Failure: The patient previously tried the step-1 medication for an adequate trial duration (under their current or a previous health plan) without clinical efficacy.
4. Expected Ineffectiveness: Based on sound clinical evidence or the patient's medical characteristics, the step-1 medication is reasonably expected to be ineffective.
5. Treatment Stability: The patient is already stable on the prescribed GLP-1, and switching to a step-1 medication would disrupt therapeutic stability or cause physical harm.

Statutory Decision Deadlines

State step therapy reform statutes mandate strict turnaround times for insurers to respond to exception requests:

Standard Request: 72 Hours
The insurer must render a written decision within 72 hours of receiving complete clinical documentation. In many states, failure to respond within 72 hours results in automatic approval.

Urgent / Expedited Request: 24 Hours
If a delay would jeopardize the patient's health or ability to regain maximum function, the insurer must decide within 24 hours.

Sample Prescriber Override Attestation

Physicians can include this override paragraph in their prior authorization submission or appeal letter:

Prescriber Exception Letter

Re: Step Therapy Override Request for [Requested Drug: e.g. Zepbound 5mg]
Patient: [Patient Name] | DOB: [DOB] | Member ID: [Member ID]

Dear Medical Director,

I am requesting a step therapy override exception on behalf of my patient, [Patient Name], for the prescribed medication [Requested Drug].

The plan requires prior trial and failure of [Required Step 1 Drug: e.g., phentermine/topiramate or older formulation]. This step-therapy requirement should be waived under standard exception criteria because:

[ ] CONTRAINDICATION: The patient has a documented contraindication to [Step 1 Drug] due to [specify condition, e.g. cardiovascular disease, glaucoma, renal insufficiency].
[ ] ADVERSE EVENT / INTOLERANCE: The patient previously trialed [Step 1 Drug] from [Date] to [Date] and experienced severe adverse reactions ([specify symptoms]).
[ ] STABLE THERAPY: The patient is currently stabilized on [Requested Drug] with documented clinical efficacy ([specify weight/metabolic progress]) and switching would cause therapy disruption.

Supporting clinical records and chart notes are attached. Under applicable state step-therapy statutes and ERISA regulations, please provide a written determination within the statutory window.

Sincerely,
[Prescriber Signature]
[NPI Number]
