The Navitus prior authorization form is the request your prescriber sends to Navitus Health Solutions asking it to approve a medication before your pharmacy fills it. Your doctor’s office handles the paperwork, but you can move the process along by knowing what the form asks for, where it goes, and what to do if coverage comes back denied. Navitus accepts requests electronically through CoverMyMeds, by fax, or by phone at 844-268-9789.
Does Your Medication Actually Need Prior Authorization
Drugs that require prior authorization are marked with “PA” on your plan’s formulary, the list of covered medications your insurer and Navitus maintain together.1Navitus. Prior Authorization You can pull up your formulary through the Navitus member portal or by calling member services at the number on the back of your insurance card. Checking before your appointment is worth the five minutes. If you know the drug needs approval, your prescriber can start the request the same day instead of finding out at the pharmacy counter.
Non-preferred medications, high-cost specialty drugs, and treatments with significant safety profiles commonly trigger the PA flag. Off-label prescriptions, where a drug is used for a condition it was not originally approved to treat, often need extra justification as well.2Academy of Managed Care Pharmacy. Prior Authorization A drug covered freely last year may require PA this year, so a current check matters.
What Goes on the Form
The form has two parts that decide whether the request moves forward: identifying information and clinical justification.
Patient and Prescriber Details
The top section asks for your full legal name, date of birth, and the member ID printed on your insurance card. Confirm the member ID digit for digit. Transposed numbers are one of the most common reasons requests bounce back before anyone reads the clinical section. Your prescriber’s portion needs their National Provider Identifier (NPI), office phone and fax, and mailing address. Errors here can get the form rejected on validation alone.
Clinical Justification
This is the section that drives the decision. Your prescriber needs to include the ICD-10 diagnosis code that matches your condition, the drug name and dosage, the quantity, and the expected duration of therapy. Navitus also wants to see what you have already tried. If the requested drug is not the first-line option on the formulary, the form should document which preferred alternatives failed or caused side effects, a process known as step therapy. Lab results, imaging, and specialist notes strengthen the case for medical necessity.
Every drug that requires PA has its clinical criteria printed on its specific form, and the submission has to show that you meet each one.3Gulf Coast Member Services. Navitus Prior Authorization and Exception to Coverage When a form comes back denied, the usual reason is that the prescriber did not document the step therapy or did not explain why the formulary alternatives are not appropriate for you.
How to Submit It
Navitus accepts PA requests through three channels. The fastest is electronic prior authorization (ePA) through CoverMyMeds, which Navitus names as its preferred method.4CoverMyMeds. Navitus Health Solutions Prior Authorization Forms Providers already using CoverMyMeds can find the correct Navitus form, complete it inside their workflow, and transmit it without leaving the electronic health record. Providers without an account can sign up and verify their NPI to begin.
Offices that prefer fax should use the right dedicated line:5Navitus. Pharmacies
- Commercial plans: 855-668-8551
- Medicare plans: 855-668-8553
A commercial request sent to the Medicare line, or the reverse, slows the process. Providers can also start or check on a request by phone at 844-268-9789.5Navitus. Pharmacies Whichever route your prescriber uses, hold onto a copy of the completed form and any confirmation number the system returns.
How Long the Decision Takes
Turnaround depends on your plan type and whether the request is standard or urgent.
For Medicare Part D coverage determinations, Navitus must respond within 72 hours of receiving a standard request.6eCFR. 42 CFR 423.568 A missed deadline counts as a denial and is forwarded automatically to an independent review entity within 24 hours. For requests marked urgent, meaning a standard wait could seriously harm your health, Navitus has indicated decisions are made within 24 hours.
For commercial and Medicaid plans, a CMS rule taking effect in 2026 requires standard prior authorization decisions within seven calendar days and expedited decisions within 72 hours.7Centers for Medicare & Medicaid Services. CMS Finalizes Rule to Expand Access to Health Information and Improve the Prior Authorization Process Pharmacy requests through Navitus often clear faster, with standard requests typically processing within about five business days.3Gulf Coast Member Services. Navitus Prior Authorization and Exception to Coverage
Approvals go out by fax to the provider and by mail to the member. Denials also come in writing to both, with the reason and the next steps spelled out.
Getting Medication While You Wait
New Medicare Part D members whose medication is not on the formulary or carries a PA restriction can get a temporary 30-day supply during the first 90 days of enrollment. If the prescription is written for fewer days, refills are allowed up to the 30-day maximum. After that initial supply, coverage stops unless the PA is approved or a formulary exception is granted.8University of California. Navitus MedicareRx (PDP) 2026 Formulary Long-term care residents past the 90-day window can still get a 31-day emergency supply while an exception is pursued.
On commercial plans, temporary-supply rules vary by employer or plan sponsor. Ask the pharmacist whether your plan allows an override fill while the PA is pending. Some plans authorize a short bridge supply, often 72 hours to a few days, but it is plan-specific and not guaranteed.
When a Formulary Exception Is the Right Form Instead
A formulary exception, which Navitus calls an Exception to Coverage (ETC), is a related but separate request. You use it when a drug is not covered, is new or not yet reviewed, is subject to a quantity limit, is gender-specific, or is flagged for high dosing.3Gulf Coast Member Services. Navitus Prior Authorization and Exception to Coverage An exception cannot lower your copay tier or override a direct plan exclusion.
The ETC form works much like the PA form. Your prescriber submits clinical documentation showing why you need the specific drug and why formulary alternatives are not appropriate, a Navitus clinical pharmacist reviews it, and the same fax lines and turnaround windows apply.
Common Reasons Requests Get Denied
- Incomplete or incorrect information. Missing patient demographics, a wrong member ID, a mismatched diagnosis code, or an invalid NPI can get the form rejected before anyone evaluates the clinical merits.
- Step therapy not documented. If the form does not show that you tried the preferred alternatives first, or explain why you cannot take them, Navitus will typically deny. This is the single most common clinical reason for denial.3Gulf Coast Member Services. Navitus Prior Authorization and Exception to Coverage
- Insufficient medical necessity. The documentation does not make a strong case for the specific drug, or the diagnosis code does not match the drug’s approved use.
- Non-formulary medication. The drug is not on the plan’s covered list, and no exception request was submitted alongside the PA.
If the denial is for missing information rather than clinical reasons, your prescriber can often resubmit a corrected form right away rather than going through a formal appeal.
How to Appeal a Denial
Every denial comes with a written notice listing the reasons. The appeal process depends on your plan type.
Commercial and ACA-Compliant Plans
You have 180 days from the date of the denial notice to file an internal appeal.9HealthCare.gov. Appealing a Health Plan Decision Staff not involved in the original decision review the request. If the standard timeline would seriously jeopardize your health or recovery, you can ask for an expedited appeal. The plan must then decide as quickly as your condition requires, and no later than four business days after receiving the request. An expedited decision can be delivered by phone but must be confirmed in writing within 48 hours.
If the internal appeal is also denied, you can request an external review by an independent review organization. The IRO’s decision is final and binding on the insurer.10Centers for Medicare & Medicaid Services. Internal Claims and Appeals and the External Review Process Overview In urgent situations, you can file the internal appeal and the external review at the same time instead of waiting for the internal process to finish.9HealthCare.gov. Appealing a Health Plan Decision
Medicare Part D Plans
Medicare uses different terms and shorter deadlines. After a coverage determination denial, you have 60 calendar days from the date on the notice to request a redetermination.11Navitus. Request for Redetermination of Medicare Prescription Drug Denial If that also goes against you, the next step is reconsideration by an independent review entity, filed within 60 calendar days of the redetermination decision. Appeals can continue to an administrative law judge and beyond, though most cases resolve at the redetermination or IRE level.
In either system, the strongest appeals bring new clinical evidence that was not in the original submission: updated labs, a letter of medical necessity from a specialist, or documentation of adverse reactions to the alternatives Navitus suggested.
