Allergy & Immunology billing · Maryland
Allergy and immunology billing services in Maryland succeed or fail on unit counting and buy-and-bill decisions, and 247MBS has managed both for allergists here since 2005.
Our HIPAA-compliant, SOC 2 Type II team bills Maryland Medicaid HealthChoice, Medicare Part B, CareFirst BlueCross BlueShield, Aetna, UnitedHealthcare and Kaiser, assigning every practice a dedicated account manager and a free real-time dashboard so antigen doses, testing units and biologic claims are visible the day they are submitted.
An allergy practice does not live on the office visit — it lives on antigen units and the economics of buying and billing drugs. Maryland raises the degree of difficulty because HealthChoice runs through nine managed-care organizations, each with its own preferred-drug list, prior-authorization portal and step-therapy logic. A biller in Baltimore may touch Priority Partners, MedStar Family Choice and CareFirst Community Health Plan in a single afternoon, and each one handles an immunotherapy or biologic request differently. Outsourcing that complexity to a team that reconciles all nine plans daily is why Maryland allergists partner with us rather than stretch a single in-house biller across the whole payer map.
As your outsourcing partner we absorb the compliance and coding load, so the practice keeps its clinical focus while the technical revenue is protected line by line.
Federal ASP/HCPCS pricing and Medicare's 95165 dosing rule set the baseline for how allergy antigens and biologics are paid; Maryland's nine HealthChoice MCOs then layer their own step-therapy and dose-cap requirements on top. That two-tier structure is where revenue leaks if claims are not built to both rule sets at once.
| Maryland allergy billing at a glance | Detail |
|---|---|
| Medicaid program | Maryland Medicaid / MDH (HealthChoice) |
| Delivery model | Managed care (9 MCOs) |
| HealthChoice MCOs | Aetna, CareFirst, Jai Medical, Kaiser, MD Physicians Care, Priority Partners, UnitedHealthcare, Wellpoint, MedStar |
| Commercial payers we bill | CareFirst BCBS, Aetna, Cigna, UnitedHealthcare |
| Medicaid appeal window | Verify at source (MCO appeal, then state fair hearing) |
| Medicaid enrollment | ~1.39 million |
Because each MCO can set its own immunotherapy dose cap and biologic prior-authorization pathway, the same severe-asthma patient may be billed three different ways depending on the plan. We maintain plan-level rule sheets so a Rockville or Columbia practice is not left guessing which portal wants what before a vial is opened.
247MBS is engineered around the lines that carry an allergy practice's margin. The 95165 antigen preparation code is the most-audited line in the specialty, so we bill it directly from your mixing log — one cc equals one dose, ten doses per vial under Medicare — and the dose count on the claim always matches the prep record. When a HealthChoice MCO or CareFirst requests documentation, the numbers already reconcile.
A medical billing services company should be judged on defensible results, and ours are compliant by design: a 99% clean-claim rate, roughly 99% net collection, accounts receivable held under 25 days, up-to-40% denial reduction, 90% recovery on worked denials, 24-hour claim submission and 98% client retention. Certified AAPC/AHIMA coders review every allergy chart. That professional discipline is why we are chosen as an allergy and immunology billing company in Maryland.
Reimbursement is driven by unit counting and the buy-and-bill decision, not the E/M. Skin and intradermal tests are billed per test inside each payer's annual cap; the antigen preparation line is billed from the mixing log; and the prep-versus-administration split means the injection code is billed once when two or more injections are given the same day. Modifier 25 belongs only on a distinct, separately documented same-day visit.
| How it's paid | Code | Maryland billing note |
|---|---|---|
| Percutaneous skin tests | 95004 | Per test; track each MCO's annual unit cap |
| Intradermal tests | 95024 | Per test; document count against caps |
| Antigen prep (single) | 95165 | Per dose from the mixing log; 1 cc = 1 dose, 10 doses/vial (Medicare) — most-audited line |
| Injection, one | 95115 | Single administration |
| Injection, two or more | 95117 | Prep-vs-admin split: billed once for 2+ injections same day |
| Biologics (asthma/urticaria) | J-code + admin | Exact HCPCS units + JW/JZ wastage; PA before administration |
| Distinct same-day E/M | 99213–99214 + mod 25 | Only when a separate, documented service occurs |
Biologics for severe asthma and chronic urticaria demand exact HCPCS unit reporting, JW/JZ wastage modifiers and prior authorization secured before administration. Across nine MCOs that PA can route nine ways, so we track each to approval before the drug is drawn.

Routed to ABN so the patient is responsible
Non-covered immunoglobulin (IgG) food panels are a frequent write-off. We route them to an ABN so the balance is properly the patient's rather than a silent loss.
From a solo allergist in Columbia to a multi-site group in the Baltimore–Washington corridor, we run the full cycle: eligibility and benefits verification, prior authorization, charge capture, coding, claim scrubbing, submission within 24 hours, payment posting, denial management and patient statements. Our medical billing for allergy and immunology in Maryland scales with your provider count and payer mix.

As an allergy and immunology billing services provider in Maryland, we tune each to the nine-MCO reality.
We bill for allergists and immunologists in Baltimore, Rockville, Columbia, Silver Spring, Frederick and Annapolis, from single-provider offices to hospital-affiliated groups and pediatric allergy clinics. Whether your revenue leans on immunotherapy build-up, food-allergy testing or biologic infusions, our workflow adapts. Practices that outsource allergy and immunology billing in Maryland keep their focus on patients while we defend the revenue behind every antigen dose and biologic claim. Choosing to outsource allergy and immunology billing in Maryland to a specialist team also removes the single-biller risk that leaves small practices exposed during turnover, vacations and portal password changes.
We begin with a revenue review of your recent allergy claims — antigen dosing, testing units, biologic PA history and denial patterns — then map each HealthChoice MCO, Medicare and commercial rule into our workflow. Your dedicated account manager configures the dashboard, connects to your EHR/PM system, and submissions begin within days with no disruption to scheduling.
Maryland allergists who move their revenue cycle to us collect more on every antigen dose, per-test skin panel, and buy-and-bill biologic — because our medical billing for allergy and immunology in Maryland is built to both rule sets at once: the federal baseline and the separate step-therapy and dose-cap logic each of the nine HealthChoice MCOs layers on top. We reconcile every dose to your mixing log, hold each test inside its plan cap, and lock biologic authorization at Priority Partners, MedStar Family Choice, CareFirst, or Kaiser before the vial is opened. Since 2005 our HIPAA- and SOC 2-compliant team has held first-pass clean-claim rates near 99% with A/R under 25 days for practices from Baltimore to Rockville. Send us your recent denials and we will quantify what is leaking.

It is the most-audited line in allergy billing. We bill it straight from your mixing log — one cc equals one dose, ten doses per vial under Medicare — so units always match the record and survive audit.
Timelines run through the MCO appeal first and then a state fair hearing; because they vary, we verify the exact window at source per plan and work denials immediately, with 90% recovery on worked claims.
Yes. We confirm prior authorization before administration, report exact HCPCS units with JW/JZ wastage modifiers, and reconcile buy-and-bill against any white-bag requirement.
No — they are typically non-covered. We route them to an ABN so the patient is properly responsible and the practice avoids the write-off.
Yes. Our model scales from single-provider practices to multi-site groups, each with a dedicated account manager and the same dashboard visibility.
