Georgia Medicaid Preferred Drug List & Prior Auth (2026)

A Georgia Medicaid drug is covered, but it still gets rejected at the counter, because only the preferred drugs on the statewide Preferred Drug List (PDL) fill without prior authorization. The same Georgia Medicaid PDL applies whichever plan you are in, so a non-preferred drug needs a prior authorization (PA) regardless of which Care Management Organization you belong to. This guide explains the difference between preferred and non-preferred drugs, the federal 72-hour emergency supply you can ask for while a PA is pending, how to get a non-preferred drug approved, what your copay is, and how Medicare interacts with Medicaid drug coverage for dual-eligibles.

Why a covered drug on the Georgia Medicaid Preferred Drug List still gets rejected

Outpatient prescription drugs are technically an optional Medicaid benefit, but every state, including Georgia, has elected to cover them, and a state that covers drugs and signs the national rebate agreement must cover essentially all FDA-approved drugs of participating manufacturers.4 So "is this drug covered?" is rarely the real question. The real question is whether it is preferred.

Federal Medicaid law lets a state steer prescribing with a Preferred Drug List and prior authorization, while protecting members with two guarantees: a PA decision within 24 hours and at least a 72-hour emergency supply.2 Georgia uses that authority to run one statewide PDL. A drug on the preferred side of a therapeutic class fills with no extra step. A drug on the non-preferred side is still covered, but the pharmacy claim rejects with a "prior authorization required" message until a prescriber documents why the non-preferred drug is the right one.

Behind that point-of-sale check sits the federal Drug Utilization Review (DUR) requirement. Every state Medicaid program must run a DUR program for covered outpatient drugs, combining prospective review (a safety check before each fill) and retrospective review (claims analysis to catch overuse and unsafe prescribing).2 That is why a claim can reject for a drug interaction, an early refill, or a quantity limit, not only for non-preferred status.

The Georgia Medicaid Preferred Drug List, explained

The Georgia Medicaid PDL is organized by therapeutic class. Within each class, drugs are designated preferred or non-preferred:

• Preferred drugs fill without prior authorization at the standard copay. Most Georgia Medicaid prescriptions are for preferred drugs.
• Non-preferred drugs require prior authorization, which typically means documenting that a preferred alternative failed, caused side effects, or is contraindicated.

DCH and the Georgia DUR Board decide preferred and non-preferred status using clinical evidence, comparative effectiveness, and manufacturer rebate offers, and they publish the prior authorization criteria, step-therapy requirements, and quantity limits. The list changes over time: new drugs are reviewed for placement once they have FDA approval and a manufacturer rebate agreement, and existing drugs can move between preferred and non-preferred status. Pull the current PDL and the class-specific PA criteria from DCH for the drug you care about, because preferred status is set per therapeutic class and updated periodically.

Before unification, each Georgia Families CMO ran its own formulary, so coverage varied by plan assignment. Georgia now runs one statewide PDL: a prescription follows the same preferred and non-preferred list and the same PA criteria regardless of CMO. The three current Georgia Families CMOs (Amerigroup Community Care, CareSource, and Peach State Health Plan) all pay for their own members' prescriptions but cannot impose a different PDL or different PA rules.1 One practical consequence: a Georgia Medicaid member cannot switch plans to get a better drug list the way a Medicare Part D enrollee can, because the list is set by the state, uniformly.

Who actually adjudicates your claim depends on how you are enrolled. Fee-for-service members go through OptumRx, the pharmacy benefits manager for the Georgia Medicaid Fee-for-Service Outpatient Pharmacy Program, which applies the PDL and PA edits and pays pharmacies. Members in a Georgia Families CMO fill through their plan and its own pharmacy benefits manager. Gainwell Technologies is Georgia's fiscal agent for the Georgia Medicaid Management Information System (GAMMIS) and the member contact center, not a statewide pharmacy benefits manager.5 A fuller breakdown of who runs the benefit is in the Georgia Medicaid pharmacy benefit manager guide.

How to get a non-preferred drug approved

When a non-preferred drug (or a preferred drug with clinical criteria, such as an opioid, a Schedule II stimulant, a biologic, or a GLP-1 agonist) is prescribed, the prior authorization flow is the same statewide:

Federal law requires that PA decision within 24 hours of a complete request.2 Several shortcuts speed approval. Auto-PA criteria can approve a request automatically when a qualifying diagnosis already appears in the member's claims history (for example, a documented diagnosis can clear the relevant therapy). Continuity-of-care provisions let a member who is already stable on a non-preferred drug keep it through a simplified transition when they become Medicaid-eligible. Step-therapy overrides let a prescriber document why step therapy is inappropriate (an allergy, a prior adverse reaction, or a contraindication).

Step therapy applies where a cheaper preferred drug must be tried first. Common Georgia Medicaid step-therapy patterns include a preferred proton pump inhibitor before a non-preferred one, a preferred SSRI before a non-preferred SNRI, a preferred statin before a PCSK9 inhibitor, a preferred TNF inhibitor before another biologic for rheumatoid arthritis or inflammatory bowel disease, and metformin, then a sulfonylurea or DPP-4 inhibitor, before a GLP-1 agonist for diabetes. A prescriber can override step therapy with documented prior failure or a contraindication.

If a denial stands after PA review, you can appeal through your CMO's appeals process or request a Medicaid fair hearing. The DCH pharmacy help desk and your CMO's member services line can also troubleshoot a specific rejection.

The 72-hour emergency supply

This is the single most useful thing to know at the counter. Federal Medicaid law requires a state's prior authorization program to let the pharmacy dispense at least a 72-hour supply of a covered outpatient drug in an emergency when authorization cannot be obtained in time.2 So if your prescriber is unreachable on a Friday evening and a PA cannot clear before the weekend, ask the pharmacist for the 72-hour emergency supply rather than leaving empty-handed. The same statute that authorizes the PDL and prior authorization is what bounds it with this guarantee and the 24-hour decision rule.2

What you pay at the pharmacy

Georgia Medicaid drug copays are nominal. Federal rule caps drug cost sharing at $4 for a preferred drug and $8 for a non-preferred drug for members at or below 150% of the federal poverty level, with those maximums indexed each October, so confirm the current Georgia amounts with DCH or your CMO member handbook.3 Total cost sharing for the household is also capped: Medicaid premiums and cost sharing may not exceed 5% of family income.3

Two protections matter most. First, several groups are exempt from cost sharing entirely. Second, a pharmacy cannot refuse to dispense a drug because you cannot pay the copay at the time of dispensing; you still owe the copay debt, but you get the medication.3

Pregnancy-related services, including pregnancy-related drugs, are exempt from Medicaid cost sharing under federal law, so a member who is pregnant pays no copay for those prescriptions.6 When a drug has a generic equivalent, the pharmacy dispenses the generic and bills the generic copay unless the prescriber marks "Dispense as Written" and the brand is medically appropriate.

Specialty drugs and how they are dispensed

Specialty drugs are high-cost, complex therapies that need special handling, patient education, and monitoring, such as biologics for autoimmune conditions, HIV antiretrovirals, hepatitis C direct-acting antivirals, cystic fibrosis modulators, multiple sclerosis disease-modifying therapies, oral oncolytics, transplant immunosuppressants, and gene therapies. Most require prior authorization documenting medical necessity, and they are dispensed through a limited specialty-pharmacy network rather than at a retail counter. Your CMO or DCH can tell you which specialty pharmacy fills a given drug; confirm the assigned pharmacy with your plan rather than assuming a particular national chain.

Some clinic-administered specialty drugs (infusions or injections given under medical supervision) can be handled two ways. With white-bagging, the specialty pharmacy ships the drug to the clinic and bills it under the pharmacy benefit. With buy-and-bill, the clinic buys the drug and bills it under the medical benefit, similar to Medicare Part B physician-administered drugs. The choice is typically made by the CMO and can be set by drug.

Does Georgia Medicaid cover Ozempic or Wegovy?

This is where "Medicaid covers all drugs" collides with the federal exclusion list. Georgia Medicaid covers GLP-1 agonists (Ozempic, Trulicity, Rybelsus, Mounjaro) for Type 2 diabetes with prior authorization and step therapy, typically requiring documented trials of metformin, a sulfonylurea, and a DPP-4 inhibitor first. Federal law lets states exclude drugs prescribed for weight loss, so the weight-loss-only versions (Wegovy, Zepbound) are not part of mandatory Medicaid coverage.4 A member who has both Type 2 diabetes and obesity can still have a GLP-1 covered for the diabetes indication. The same logic applies to other excludable categories: drugs for weight gain, fertility, cosmetic use, and erectile dysfunction sit on the optional-exclusion list, while a state may cover some of them or cover specific molecules for a non-excluded use.

If you have Medicare and Medicaid

If you are enrolled in both Medicare and Medicaid (a dual-eligible), your prescription drugs run primarily through Medicare Part D, not Georgia Medicaid. Most drugs are covered by your Part D plan (a standalone plan, a Medicare health plan that includes drug coverage, or a dual-eligible special needs plan), and dual-eligibles automatically receive Extra Help, which sharply reduces or eliminates Part D premiums, deductibles, and copays.4

Georgia Medicaid provides only wrap-around coverage for the narrow set of drugs Part D excludes, which can include certain over-the-counter drugs Georgia Medicaid covers with a prescription, some barbiturates and benzodiazepines, weight-loss drugs when medically necessary, and a few vitamins and cough-and-cold products the state elects to cover. For most of a dual-eligible's drug spending, the answer to "which card do I use?" is the Part D card.

Worked examples

These illustrative scenarios show how the PDL, prior authorization, and copay rules play out. They are hypothetical composites, not real members, and the dollar figures reflect the federal nominal copay framing rather than a specific Georgia fee schedule.

Maintenance refills with a 90-day option

A member with Type 2 diabetes and hypertension takes several stable maintenance drugs (a metformin, a lisinopril, a statin). All are preferred, so they fill at the generic copay with no prior authorization. For the most stable ones, she moves to a 90-day fill through her CMO's mail-order pharmacy, which consolidates her copays and reduces pharmacy trips. Generic substitution applies automatically.

A non-preferred ADHD stimulant for a child

A child on PeachCare for Kids takes a long-acting Schedule II stimulant for ADHD. The drug is non-preferred, so a prior authorization documents that he needs the long-acting form for school-day coverage and has been stable on it. Because Schedule II prescriptions cannot have refills under federal law, the pediatrician writes a new prescription each cycle, and the pharmacy checks the Georgia Prescription Drug Monitoring Program at each fill. As a child under 21, he has no copay.3

Pregnancy prescriptions at no copay

A member on Pregnancy Medicaid fills a prenatal vitamin, an anti-nausea drug, and later an antibiotic and insulin for gestational diabetes. Every pregnancy-related prescription is exempt from cost sharing, so she pays nothing for them during the pregnancy.6

A GLP-1 agonist that needs step therapy

A member with Type 2 diabetes, depression, and obesity is already on a preferred SSRI, metformin, a sulfonylurea, and a DPP-4 inhibitor, but her HbA1c is still above target. Her endocrinologist adds a GLP-1 agonist, which is non-preferred and requires step-therapy documentation. The PA records the prior failed therapies and the clinical need, the request is approved, and the drug dispenses at the brand copay through a specialty pharmacy.
