What makes pharmacy billing different
Our pharmacy billing services cover the drug side of the revenue cycle: physician-administered drugs billed on medical claims, the split between the medical and pharmacy benefits, NDC reporting requirements, and the prior authorization work that specialty drugs demand. Pharmacies, infusion centers and dispensing practices all face the same core question on every expensive drug: which benefit covers it, and what does the claim have to show. Fastora's certified billing and coding professionals handle drug claims as part of our wider medical billing services.
Drug claims carry the highest dollar amounts on a medical claim and the strictest documentation rules. A missing NDC, a wrong benefit or a lapsed authorization can hold up a five-figure claim for months. We run eligibility and benefits checks before high-cost drugs are ordered or administered, confirming the benefit, the authorization requirement and the patient's cost share up front.
Medical benefit vs pharmacy benefit
| Drug type | Usual benefit | How it bills |
|---|---|---|
| Physician-administered infusions and injections | Medical benefit | J-codes on the medical claim by the practice |
| Self-injectables and oral specialty drugs | Pharmacy benefit | NDC through the pharmacy benefit manager |
| Nebulizer and inhalation drugs | Either, by payer | Medical or DME benefit depending on the plan |
| Vaccines | Either | Medical benefit in clinic, pharmacy benefit at retail |
The same drug can bill to different benefits depending on where and how it is given. An injectable administered in the office goes to the medical benefit with a J-code; the self-injectable version of a similar therapy goes to the pharmacy benefit with an NDC. Routing the claim to the wrong benefit is an automatic denial. We verify the benefit for each drug, site and payer combination before the claim is built, and we keep site-of-care policies on file since some plans steer infusions to home or designated centers.
NDC reporting on medical claims
Physician-administered drugs billed on medical claims increasingly require the 11-digit NDC alongside the J-code, plus the unit of measure and the quantity administered. Payers use the NDC to check rebate and pricing programs, and a missing or mismatched NDC rejects the line even when the J-code is right.
For drugs from single-dose vials, discarded amounts are reported with the JW modifier and zero-waste claims with JZ, following the same rules as infusion billing. We pull the NDC from the administered vial, not from a default list, because vial sizes change and the NDC on the claim has to match what was actually given.
Buy-and-bill for administered drugs
Buy-and-bill means the practice purchases the drug, administers it and bills the payer for the drug and its administration. The inventory cost sits with the practice until the claim pays, so drug claims need first-pass accuracy and fast follow-up.
Our A/R management tracks drug receivables separately from visit receivables, because a stalled drug claim distorts the whole aging picture. High-balance drug claims are worked by payer and age on a shorter cycle than routine claims, and denial patterns feed back into ordering and documentation so the same drug does not deny twice.
Prior authorization for specialty drugs
Specialty drugs almost always need prior authorization, and most plans apply step therapy or site-of-care rules before approving. Requests need the diagnosis, prior therapies with dates and outcomes, lab values where the label requires them, and the dosing plan.
Our prior authorization team builds the request from the chart, tracks reauthorization dates so maintenance therapy does not lapse, and handles peer-to-peer scheduling when the plan requires a clinician conversation. For drugs dispensed through a specialty pharmacy, we coordinate the benefit investigation so the prescription does not stall between the office and the pharmacy.
340B program awareness
Facilities that participate in the 340B drug pricing program buy covered outpatient drugs at a discount, which creates billing duties around them: claims must avoid duplicate discounts when the drug is also subject to Medicaid rebates, and contract pharmacy arrangements need clear records of which prescriptions qualify.
We do not certify 340B eligibility, but we keep billing aligned with the program's rules: correct modifiers where payers require them to identify 340B claims, clean separation of Medicaid and non-Medicaid utilization, and documentation that supports the claim if a manufacturer or payer questions it.
How Fastora supports pharmacy billing

Fees are quoted after a free assessment, so we can see your drug mix, benefit split and authorization patterns first. Start with a free billing assessment and we will show you where drug claims are slowing down before you commit to anything.
Pharmacy medical billing: buy-and-bill and medical-benefit claims
Pharmacy medical billing covers the drugs billed on the medical benefit rather than the pharmacy benefit: buy-and-bill infusions and injections administered in the office, with J-codes, units, waste documentation, and prior authorization all on the same claim. The common failures are unit mismatches, missing authorization for high-cost drugs, and payer rules that route a drug to the pharmacy benefit instead. Each claim is checked against the payer's drug policy before submission — not after the denial. Our medical coding service reviews J-code units against administration records, our credentialing and enrollment team keeps infusion providers enrolled, a free medical billing audit shows where drug claims stall.
