Specialty billing · Allergy & Immunology
Every antigen dose, testing unit, and biologic — paid the first time.
247 Medical Billing Services runs allergy and immunology billing services that get every antigen dose, testing unit, and biologic paid the first time — across Medicare, Medicaid, and commercial payers. You get a dedicated account manager, a free 360° reporting dashboard, and HIPAA- and SOC 2-compliant workflows built by a team that has managed allergy and immunology revenue cycles since 2005.
Highlighted stages are where biologic revenue is most often lost
The practice prepares antigen extract in-house, stores it, draws each dose from a multidose vial, and bills for both the preparation and the injection.
Testing per individual test, antigen by the counted dose, biologics by the HCPCS unit — nothing else on the fee schedule behaves like it.
Allergy and immunology is one of the few office specialties where both are true at once.
Count the doses right, split preparation from administration cleanly, and clear the authorization first, and every one of those claims pays predictably.
On top of the antigen line sits a second buy-and-bill line for severe-asthma and chronic-urticaria biologics that can run past $30,000 a year per patient.
Let a single variable slip — a skin-test panel billed as one unit, an eleventh dose drawn from a ten-dose vial, a modifier 25 stapled to a routine shot, a biologic infused before approval — and the money either shrinks quietly or comes back as a recoupment months later.
We built our allergy and immunology billing around that reality — closing each gap at the front end so more claims pay on the first pass, fewer dollars get clawed back, and your clinical team never has to stop between patients to settle a unit-counting question.
Reported per individual test, inside each payer's annual cap.

$30,000+a year per patient — the second buy-and-bill line in the practice
We manage every unit rule and service split so each encounter is paid to its true value — nothing rounded away, nothing left uncaptured, nothing billed in a way that invites a takeback:

Why each row matters
Each row is a place where allergy care quietly leaks revenue. Skin testing turns on the per-test count and each payer's annual cap; report the panel as "1" and every workup in the practice is underbilled. Antigen preparation lives or dies on the 95165 dose definition — a 1 cc aliquot, ten billable doses per multidose vial for Medicare, reconciled line by line against your mixing log. Administration has to be separated from preparation so you bill only the service you actually rendered, and 95117 has to be reported once no matter how many injections were given. Biologics pay only when the HCPCS unit math is exact, the discarded-drug modifier is attached, and the prior authorization is on file before the dose goes in. We run each of these before the claim ever leaves the practice.
95165× 20 units1 cc / dose · inside the 30-unit daily MUEBilled units equal documented doses — survives the audit reconciliation
Outsourcing makes unusual sense in allergy and immunology because the specialty's whole margin hides inside rules that a general biller almost never touches.
The 95165 dose definition, the ten-doses-per-vial Medicare cap, the per-test skin-testing count, the prep-versus-administration split, venom-by-venom coding, and JW/JZ wastage on five-figure biologics are not skills that transfer from an E/M-heavy book of business — they have to be learned specifically, and the single 95165 unit is the most-audited line in the specialty.
When that expertise sits on one in-house desk, the highest-dollar and highest-risk claims in the practice are exactly the ones that stall the week that person is out.
When you outsource allergy and immunology billing services to us, that specialized knowledge stops being a staffing gamble and becomes a standing capability. A certified team already fluent in antigen-dose counting and biologic buy-and-bill works your claims on a transaction-based fee, the audit-exposed lines get built to survive reconciliation every day, and you replace the fixed cost — and the single point of failure — of an in-house specialist with a bench that never takes a day off.
For a practice where one clawed-back antigen vial or one denied biologic can dwarf a month of billing fees, that trade pays for itself quickly.

Outsource allergy and immunology billing to us and the highest-dollar, highest-risk claims in your practice stop riding on one in-house desk that goes dark the week that person is out.
For most practices, allergy and immunology billing services outsourcing pays for itself the first time a clawed-back vial or a denied biologic is prevented rather than appealed months later.
DATAYour data on one dashboardDENIALSUp to 90% of worked denials overturned95165No vial billed that you didn't mixEverything it takes to move an allergy claim from the chart to paid, run by one certified team rather than split across vendors:
Testing units tied to the number of tests performed, 95165 doses billed straight from the vial preparation log, venom coded by venom count, and modifier 25 vetted on every same-day E/M.
Coders who know the prep/admin split, the 95165 dose definition, and the JW/JZ wastage rules cold, so nothing is downcoded and nothing invites a takeback.
Providers enrolled and re-credentialed, and biologic authorizations secured before administration so the largest denial category never starts.
Every claim scrubbed and filed within 24 hours across Medicare, Medicaid, and commercial payers.
Every denial worked to root cause, from dose over-units to medical-necessity screens on large testing panels, appealed inside each payer's clock.
Aged-A/R recovery across Medicare, Medicaid, and commercial payers, and posting — one connected process on one dashboard your named account manager reviews with you.
If you'd rather keep allergy and immunology billing and coding services under one roof, that's exactly the model — certified coders and billers on the same team, sharing the same record, instead of handing your claims between companies.
Bringing us on isn't hiring a general biller who happens to accept allergy claims. It's engaging an allergy and immunology billing company that already knows where this specialty's revenue leaks and how to stop it before it starts:
Every 95165 unit is billed from the vial preparation log against the 1 cc-per-dose and ten-doses-per-vial rules, so you collect the doses you actually prepared and survive the reconciliation when the auditor asks.
Skin-test units match the number of tests performed and sit inside each payer's annual cap, so entire allergy workups stop being underbilled as single panels.
Antigen and administration lines are billed only for the service you actually rendered, capturing every dollar you earned without billing a vial you didn't mix.
HCPCS unit math is validated milligram by milligram, JW/JZ wastage is attested on every single-dose drug, and prior authorization is confirmed before administration.
A named account manager owns your account and a free live dashboard shows every claim, denial, and dollar — with no long-term lock-in holding you there.
Practices that move their revenue cycle to us typically see:
We hold a 98% client-retention rate because those numbers hold month after month, and every claim is scrubbed and filed within 24 hours so revenue that used to sit in a work queue starts landing in your account instead. That is what professional allergy and immunology billing services look like when a specialist team owns the cycle end to end.
Revenue review
A certified allergy billing specialist reviews your antigen-dose counts, testing units, biologic authorizations, and aged A/R — and puts a dollar figure on what your miscounted antigen doses, downcoded testing, and aged A/R are actually costing.

A generalist learns allergy on your claims. We show up already fluent in it — and the difference shows up on the remittance:
Most allergy losses trace back to the same handful of failure points. We close each one at the front end, before it becomes a denial or a recoupment:
95165 units billed by clinical judgment or every draw
Overpayment recoupment and False Claims Act exposure — the specialty's #1 audit target
We bill every dose from the mixing log: 1 cc per dose, ten doses per vial, inside the 30-unit/day MUE
Skin-test panel reported as one unit (95004/95024)
Systematic underpayment on every allergy workup
We set units to the number of tests performed and hold them inside payer annual caps
95117 billed once per injection
Overbilling denial and audit flag
We bill 95117 a single time for two or more injections, never multiplied
Antigen code billed for a vial the practice didn't prepare
Compliance exposure and takeback
We bill the antigen line only when we prepared it; otherwise only the administration code
Modifier 25 on a routine immunotherapy visit
Same-day E/M denial and a standing OIG audit theme
We require a distinct, documented visit before appending modifier 25 — never on a scheduled shot
Biologic billed without JW/JZ or correct units
Claim returned as unprocessable and wastage recoupment
We validate mg-administered-vs-discarded and hard-stop JW/JZ on every single-dose drug
Large testing panel or IgG food-sensitivity test billed to the payer
Medical-necessity takeback on non-covered testing
We screen non-covered panels into ABN/patient-pay before submission
Every one of these is preventable before submission rather than argued after the fact. Request a revenue review and we'll show you which of them is hitting your remits right now.
