A GLP-1 prior authorization is a coverage request the clinic sends to the patient's plan or pharmacy benefit manager before it will pay for a drug such as Wegovy or Zepbound. Approval usually depends on documented BMI, diagnoses and history. Ona keeps the chart, the PA task, the fax response and the patient conversation on one record.

Quick answer:

  • Check coverage before you build the request. Many plans exclude weight-loss drugs entirely, some prefer one GLP-1 over another, and a PA cannot fix an exclusion.
  • Build the request from the chart: a dated BMI, coded diagnoses, the weight-related conditions the plan names, and the lifestyle and history documentation the criteria ask for.
  • Track every PA as work with an owner and a date: submission, response, approval window and the reauthorization due before it expires. Denials are usually a documentation gap or a formulary rule, and both have a next step.

Why GLP-1 Prior Auths Take So Much Staff Time

The clinical decision takes minutes. The paperwork around it is what fills a coordinator's week. Three things make GLP-1 PAs heavier than most:

  • Coverage varies plan by plan. West Virginia Medicaid's Wegovy criteria, effective January 1, 2026, state that agents used for weight loss are typically a benefit exclusion and that coverage is considered only for the secondary prevention of a cardiovascular event or MASH. California's Medi-Cal Rx stopped covering GLP-1 drugs for weight loss from January 1, 2026, per its GLP-1 Coverage Considerations notice. Commercial plans differ again.
  • Formularies have preferences. CVS Caremark's Zepbound exception criteria (6981-A) name Wegovy as the formulary alternative and require documentation that the patient had an inadequate response, intolerance or contraindication to it before the exception is granted.
  • Approvals expire. The same Caremark document lists a 12-month duration of approval. West Virginia Medicaid's Wegovy criteria allow 90 days initially and six months on continuation. Every approval is a future task.

None of this is unusual for specialty drugs. What makes GLP-1s different is volume: a weight program can generate a PA, a reauthorization and often an appeal for every active patient, every year.

What Payers Typically Ask For

Criteria vary, so always work from the plan's current form. The items below come up across the payer documents we reviewed for this piece; treat them as a checklist of what to have ready, not as any one plan's rules.

What the plan asks forExample from a payer documentWhere it should live in the chart
The indication and diagnosis codesMedi-Cal Rx denies Wegovy MASH claims that lack the qualifying ICD-10-CM codesCoded diagnoses on the visit, such as E66.81x plus a Z68 BMI code
A documented BMI with a dateWV Medicaid asks for the date and result of the most recent BMI calculationWeight, height and calculated BMI in the visit's vitals
Weight-related or qualifying conditionsCaremark's form restates the label indication: obesity, or overweight with at least one weight-related comorbid conditionDiagnoses on the chart, each with its own code
Lifestyle or behavioral modificationWV Medicaid asks for an attestation of a reduced-calorie diet and increased physical activityAssessment and plan in the note, the care plan, counseling visits
Labs within a windowWV Medicaid's cardiovascular pathway asks for an HbA1c from the last 6 monthsLab reports on the chart with dates
Prescriber qualificationsWV Medicaid's cardiovascular pathway requires a prescriber in, or consulting with, named specialtiesThe prescriber's profile and any consult letter
Formulary alternative triedCaremark's Zepbound exception requires documented inadequate response, intolerance or contraindication to WegovyMedication history and the notes that recorded the outcome
Continuation evidencePlans set their own continuation criteria and approval periodsFollow-up notes, vitals trends, adherence documented at each visit

This is administrative work, not clinical guidance. Which drug to request, and whether a patient meets a plan's clinical criteria, stays with the prescriber.

The Workflow, Step by Step

1. Check coverage before the first visit

Run the medical eligibility check at booking and confirm the pharmacy benefit separately, because a GLP-1 prescription is usually adjudicated by the PBM, not the medical plan. Ask the plan or PBM three questions: is the drug covered for this indication, is a PA required, and is there a preferred alternative. Record the answer on the patient's chart. If the drug is excluded, the conversation with the patient is about self-pay or alternatives, and no amount of documentation changes it.

In Ona, medical eligibility runs automatically when a patient books, when their insurance changes and in the 48 hours before the visit, through your clearinghouse. Pharmacy benefit answers from a phone call or portal belong in the chart as a note.

2. Document for the form, not after it

Pull the plan's current PA form before the visit and chart against it. Most denials for missing information are things that happened in the room but did not make it into a structured field: the BMI was discussed but not recorded with a date, the comorbidity was mentioned but not coded, prior attempts were described but not written down.

In Ona, weight and height are vitals and BMI is calculated from them, with trends. Diagnoses are coded with ICD-10-CM at the point of charting, and Ona will not let you chart a non-billable category code. Intake forms and AI interviews can collect prior weight attempts and current medications before the visit, so the history is on the chart before anyone opens the PA form.

3. Submit and create the follow-up in the same minute

Submit through the channel the plan or PBM requires: its portal, its fax form or electronic PA. Then, before moving on, create the follow-up. The PA that gets lost is the one nobody owns.

In Ona, make each PA a task linked to the patient, with one owner, watchers if needed, a deadline and a reminder. Tasks show amber on the day they are due and red when overdue, and the board can be filtered by teammate or tag such as "Prior auth", so the coordinator's Monday list writes itself.

4. Catch the response wherever it arrives

Responses come back by fax, through the PBM portal, or as a pharmacy message. In Ona:

  • Incoming faxes are classified by AI as referral, lab results or prior-authorization response, with the patient and sender read off the page, and the tasks badge on a fax starts a task already linked to it. See faxes and referrals.
  • Prior authorization outcomes reported through DoseSpot arrive in Ona's notification bell, alongside refill requests and failed transmissions, and you respond in DoseSpot. See e-prescribing.

5. Record the approval and its end date

An approval is only useful if someone knows when it ends. Put the approval number and the valid-through date on the chart and set a reauthorization task well before expiry, because a lapse usually means the patient finds out at the pharmacy counter.

If the payer authorizes a set of visits rather than a drug, for example a counseling program, Ona tracks it under Scripts & Auths on the visit's insurance page: the authorization number, total, used and scheduled visits, and the valid-from and valid-until dates. Ona calculates remaining visits, flags visits scheduled after the authorization ends or beyond its visit count, and moves out-of-date records into a collapsed section, per the prior authorizations guide. Authorization problems show up in the eligibility verdict even when coverage itself is eligible.

6. Work denials as a list, not a pile

Read the denial reason before doing anything else. Most fall into a handful of groups, and each has a next step:

Denial reasonUsual next step
Drug excluded from the benefitNo PA fixes this. Discuss self-pay or alternatives with the patient, and check for an exception process
Missing or undated BMIResubmit with the dated vitals from the chart
Diagnosis not documented or not codedCode the diagnosis on the visit, then resubmit
Preferred alternative not triedDocument prior use and outcome, or request a formulary exception with the reason
Lifestyle or program criteria not metAttach the documentation of the program, or wait until the plan's required period is complete
Continuation criteria not metCheck the plan's continuation rules and the follow-up documentation before appealing
Expired authorizationSubmit a reauthorization and set the next reminder earlier

When documentation is complete and the plan still says no, the plan's appeal process is the next step: a peer-to-peer review where offered, then a written appeal with the plan's deadlines. Each appeal is another dated task.

7. Keep the patient informed

Patients waiting on a PA call the front desk, text the nurse and email billing, usually about the same question. In Ona's omnichannel inbox, calls, texts, email and portal messages land in one conversation per patient, and internal notes let staff record "PA submitted, waiting on fax" without the patient seeing it. One message at each milestone (submitted, decision, next step) cuts most of the follow-up calls.

Who Does What in a Busy Program

In a larger program or a multi-location group, splitting the work keeps prescribers out of the paperwork:

  • Prescriber: the clinical decision, the note, and signing anything that needs a clinician's signature.
  • Medical assistant or nurse: vitals, intake review, gathering labs and records, preparing prescriptions for the prescriber to send.
  • PA coordinator or front desk: coverage checks, form assembly, submission, follow-up tasks, patient updates.
  • Biller: visit claims, denials on the medical side, payer correspondence.

In Ona, staff on proxy accounts can queue prescriptions in DoseSpot for a prescriber to review and send, and a billing partner can work in the same claims queue on a staff seat ($45 per month). Practitioner seats are $130 per month, and e-prescribing is +$45 per prescribing practitioner. GLP-1 prescriptions do not need the EPCS add-on.

Frequently asked questions

What do insurers need for a Wegovy or Zepbound prior authorization?

It varies by plan, but common items are the indication and diagnosis codes, a documented BMI with a date, weight-related conditions, documentation of a reduced-calorie diet and physical activity, and sometimes recent labs or a preferred alternative tried first. Always work from the plan's current form, because criteria and coverage change.

Why was my patient's GLP-1 prior authorization denied?

Common reasons are that the drug is excluded from the patient's benefit, the BMI or diagnosis was not documented, a preferred alternative was not tried, program or continuation criteria were not met, or the authorization expired. Read the denial reason first. An exclusion needs a different conversation, while missing documentation can usually be fixed and resubmitted.

How long does a GLP-1 prior authorization last?

It depends on the plan. CVS Caremark's Zepbound exception criteria list a 12-month approval, while West Virginia Medicaid's Wegovy criteria allow 90 days initially and six months on continuation. Record the valid-through date on the chart and set a reauthorization task well before it, so the patient does not find out at the pharmacy.

Does Ona submit GLP-1 prior authorizations?

Ona does not describe submitting medication PAs itself. It handles the work around them: the chart the request is built from, tasks with owners and deadlines, incoming fax responses classified as prior-authorization responses, and DoseSpot prior authorization outcomes in the notification bell. Visit authorizations are tracked under Scripts & Auths with remaining visits.

How should clinics track prior authorization expiry dates?

Treat every approval as a future task. Record the approval number and end date on the chart, then create a reauthorization task with an owner and a deadline ahead of expiry. In Ona, tasks turn amber on the due day and red when overdue, and visit authorizations show as out of date after their valid-until date.

Do GLP-1 prescriptions need EPCS?

No. EPCS is for controlled substances, and GLP-1 prescriptions go through standard e-prescribing. In Ona, e-prescribing runs on DoseSpot inside the chart for +$45 per prescribing practitioner per month. The +$25 EPCS add-on only matters if your program also prescribes a scheduled drug.
