Allergy & Immunology billing · Massachusetts
Allergy and immunology billing services in Massachusetts turn on unit counting and buy-and-bill economics, not the office visit — and that is precisely the ground 247MBS has covered for allergists since 2005.
Our HIPAA-compliant, SOC 2 Type II team bills MassHealth ACOs and MCOs, Medicare Part B, Blue Cross Blue Shield of Massachusetts, Harvard Pilgrim, Tufts Health Plan and Cigna, giving every practice a dedicated account manager and a free real-time dashboard that shows antigen doses, testing units and biologic claims the day they go out.
For an allergy practice, margin is decided at the antigen vial and the injection log. Massachusetts complicates that picture with a layered MassHealth structure: Accountable Care Organizations and MCOs sit alongside a Primary Care Clinician (PCC) Plan that pays fee-for-service, so the same immunotherapy or biologic order can follow an ACO pathway, an MCO pathway or straight FFS depending on the member's enrollment. Federal ASP/HCPCS pricing and Medicare's 95165 dosing definition set the baseline; the ACO/MCO layer then adds its own step-therapy and dose-cap logic.
| Massachusetts allergy billing at a glance | Detail |
|---|---|
| Medicaid program | MassHealth / EOHHS |
| Delivery model | ACO/MCO + PCC Plan (fee-for-service) |
| MassHealth plans | Tufts Health Together, WellSense, Mass General Brigham, Fallon, Be Healthy, Boston Children's |
| Commercial payers we bill | BCBS of Massachusetts, Harvard Pilgrim, Tufts Health Plan, Cigna |
| Medicaid appeal window | 30 days (Board of Hearings; varies) |
| Medicaid enrollment | ~1.55 million |
A Boston allergy group may see MassHealth ACO members, commercial BCBS patients and Medicare beneficiaries in the same clinic day, each with a different rule for immunotherapy dosing and biologic prior authorization. We maintain plan-level rule sheets so a Worcester or Springfield practice knows which pathway governs each claim before a vial is opened.
247MBS is built around the lines that actually pay an allergy practice. 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 MassHealth ACO or BCBS of Massachusetts asks for documentation, the numbers already reconcile.
We are the kind of professional partner an allergist should expect from a medical billing services company: compliant, defensible metrics and no guesswork. That means 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, with certified AAPC/AHIMA coders reviewing every allergy chart. It is why practices choose us as their allergy and immunology billing company in Massachusetts.
Unit counting and the buy-and-bill decision drive reimbursement. 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 | Massachusetts billing note |
|---|---|---|
| Percutaneous skin tests | 95004 | Per test; track each plan'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 require exact HCPCS unit reporting, JW/JZ wastage modifiers and prior authorization secured before administration. Across MassHealth's ACO and MCO options that PA can route several ways, so we track each to approval before the drug is drawn.
Most allergy denials are preventable and trace to a short list of causes. We map each to a fix upstream of submission.

With MassHealth split across ACOs, MCOs and a PCC/FFS plan, and a 30-day Board of Hearings appeal clock that varies by program, a practice benefits from one team that already knows every pathway. Outsourcing shifts the burden of step-therapy tracking, dose-cap monitoring and biologic prior authorization onto specialists who do it all day.
