Does NADAC include dispensing fees? No. The National Average Drug Acquisition Cost measures one thing: what retail pharmacies pay their wholesalers for the drug itself. It says nothing about the pharmacist's time, the vials, the labels, the rent, or the lights. All of that lives in a separate number called the professional dispensing fee, and the two numbers meet only at the moment of reimbursement.
This split is the entire architecture of Medicaid pharmacy payment. The federal rule is that state Medicaid programs reimburse the ingredient cost at the lower of NADAC, the state maximum allowable cost, the federal upper limit, or the pharmacy's usual charge, and then add a dispensing fee on top. Ingredient plus service, two lines on the claim, always. Indiana's Medicaid bulletin phrases it exactly that way: NADAC plus any applicable professional dispensing fee. The fee is not inside NADAC. It is the plus.
A concrete example helps. If NADAC for a generic is $4.20 for a 30-day supply, the pharmacy's ingredient reimbursement centers on $4.20, and the dispensing fee is added as its own line. The total claim is the ingredient cost plus the fee, before any other adjustments. Anyone who quotes the $4.20 as the cost of filling the prescription has dropped the second number.
The fee numbers are public and they vary by state. West Virginia law sets the dispensing fee at $10.49 on top of NADAC. California's Medi-Cal fee sits at $10.05. These are not guesses; states set them from cost-of-dispensing surveys, which ask pharmacies what it actually costs to fill a prescription once the pills are paid for. When Maryland passed SB 438 in 2025, it required Medicaid to pay at least NADAC plus the fee-for-service dispensing fee, because pharmacies were being reimbursed below what the drugs cost them.
Does NADAC include dispensing fees in PBM contracts? That is the fight
Here is where the clean formula gets dirty. Pharmacy benefit managers reimburse pharmacies too, and for years the spread between what a PBM charged a health plan and what it paid the pharmacy, spread pricing, was the industry's quiet margin. A wave of state laws is now pinning PBM reimbursement to the same NADAC-plus-fee formula. Idaho, Vermont, Utah, and Oklahoma have banned spread pricing, and several states mandate reimbursement floors at NADAC plus dispensing fees of $10 to $15. California's SB 41 goes further, delinking PBM compensation from drug prices entirely and passing 100 percent of manufacturer rebates to payers.
Spread pricing worked because nobody could see it. The plan paid the PBM $50 for a prescription, the PBM paid the pharmacy $30, and the $20 stayed in the middle. NADAC-based floors kill the spread by pinning both sides to a public number. That is why the PBM lobby fights these bills and why independent pharmacies cheer them. The formula is the same either way. The winners are different.
A tangent worth taking: the clearest public window into all of this is not a government site. 46brooklyn Research, an independent drug-pricing research shop, has published free NADAC dashboards since 2019, and much of the sharpest analysis of what pharmacies actually pay versus what patients pay is built on their work. A federal survey produces the number; a small independent team made it legible. That tells you something about where the transparency in this market actually comes from.
So if you are a patient staring at a cash price that looks nothing like NADAC, now you know the shape of the gap. NADAC never promised to be your price. It is the pharmacy's cost of goods, the dispensing fee is the pharmacy's cost of doing the job, and everything else in the chain, rebates, spreads, PBM margins, sits outside both numbers. NADAC is the most honest number in drug pricing and it still is not your price. Remember that the next time a PBM tells you it is.

Frequently asked questions
What is the NADAC dispensing fee?
There is none inside NADAC. The professional dispensing fee is a separate, state-set payment added at reimbursement, for example $10.49 in West Virginia and $10.05 under California Medi-Cal.
Is NADAC the price patients pay?
No. NADAC is the national average of what retail pharmacies pay wholesalers to acquire the drug. Patient prices add dispensing costs, PBM margins, and plan design on top.
Why do pharmacies say NADAC reimbursement is too low?
Because ingredient reimbursement at NADAC plus a fixed fee can fall short of a pharmacy's total costs, especially when PBMs reimburse below the NADAC-plus-fee floor states are now mandating.
Does Medicare use NADAC plus a dispensing fee?
No. Medicare Part D runs on negotiated prices and rebates, not NADAC. The NADAC-plus-fee formula is a Medicaid construct that states are extending to PBM contracts by law.
Where can I look up NADAC prices?
CMS publishes the weekly NADAC file, data.medicaid.gov hosts the dataset, and our lookup tool tracks it with search by drug name.
