Allergy & Immunology billing · Michigan
Practices searching for dependable allergy and immunology billing services in Michigan get a partner in 247MBS that has run this specialty since 2005 — a dedicated account manager, a free real-time dashboard, and HIPAA plus SOC 2 Type II controls on every claim. We bill the MDHHS Medicaid book, the nine Medicaid Health Plans, Medicare, and the commercial carriers your Detroit and Grand Rapids patients actually carry, so antigen units, skin-test caps, and biologic buy-and-bill all land the first time.
Allergy revenue in Michigan is decided at the unit-and-vial level, not the encounter level, and the payer mix here is unusually crowded. With nine Medicaid Health Plans riding on top of MDHHS fee-for-service, one antigen policy rarely fits the next contract, and a mixing log that satisfies Priority Health can still trip an edit at Molina. That is the intersection this page owns.
Michigan billing at a glance
| Item | Detail |
|---|---|
| Medicaid program | MI Medicaid / MDHHS |
| Delivery model | Managed care (9 MHPs) + fee-for-service |
| Major plans | Aetna, Blue Cross Complete, HAP CareSource, McLaren, Meridian (Centene), Molina, Priority, UnitedHealthcare, UP Health |
| Appeal window | 120 days (MOAHR) |
| Medicaid enrollment | ~2.20 million |
Two Michigan realities shape the workflow. First, the 120-day MOAHR appeal runway is generous, but a denial only reaches a fair hearing after the plan's own internal appeal is exhausted — so a Meridian or HAP CareSource redetermination has to be filed cleanly and early, not saved for the deadline. Second, the Upper Peninsula and northern Lower Peninsula are served by different plan footprints than metro Detroit, and rural allergy practices frequently see UP Health or McLaren where a Warren office sees Blue Cross Complete. We map each patient's plan to its antigen and immunotherapy policy before the claim goes out, which is where a Michigan-specific billing company earns its keep.
247MBS is built for the line items that decide an allergy practice's margin, and we hold the compliance credentials Michigan payers expect from a professional partner. Our certified AAPC and AHIMA coders reconcile every 95165 claim to the mixing log — one cc per dose, ten doses per vial under Medicare rules — so billed doses never exceed what was actually prepared, the single most-audited line in this specialty. We keep a 99% clean-claim rate, net collections near 99%, and A/R under 25 days, and we submit inside 24 hours. As an HBMA-member medical billing services company with 98% client retention, we bring the documentation discipline that survives an MDHHS or MHP post-payment review — not just faster data entry.
Getting paid across MDHHS and the nine MHPs comes down to unit counting, the prep-versus-administration split, and buy-and-bill economics on biologics. Skin testing is billed per test inside each plan's annual cap; antigen preparation and injection are separate events; and every biologic dose needs HCPCS units plus the JW/JZ wastage modifiers and prior authorization on file.
| Service | Code | Michigan billing note |
|---|---|---|
| Percutaneous skin test, per test | 95004 | Count each test; watch annual per-test caps by plan |
| Intradermal skin test, per test | 95024 | Documented test count must match units billed |
| Antigen prep, single-dose vial | 95165 | Doses billed = mixing log; 1 cc/dose, 10 doses/vial (Medicare) |
| Immunotherapy injection, single | 95115 | One unit per single injection |
| Immunotherapy injection, 2+ | 95117 | Bill once for two or more injections, not per shot |
| Biologic administration (e.g., omalizumab) | J-code + 96372/96401 | HCPCS units + JW/JZ; prior auth before buy-and-bill |
| Office E/M, same day as service | 99213–99214 + mod 25 | Modifier 25 only for a distinct, separately identifiable visit |
Most lost dollars in Michigan trace back to a handful of predictable, preventable edits. We work them as denial-prevention rules, not as a rework queue after the money is already gone.

Revenue review
A certified allergy billing specialist reviews your coding, unit counts, authorizations and aged A/R against the payers you actually bill in Michigan — and puts a number on what your current process is leaving on the table.

Michigan allergists carry a payer matrix — MDHHS fee-for-service plus nine managed plans — that few front-desk teams can track alongside patient care. When a coder has to remember that one plan caps percutaneous tests differently than the next, and that buy-and-bill omalizumab needs authorization before the vial is even ordered, in-house billing quietly leaks revenue through undercounted antigen doses and preventable write-offs. Outsourcing to a specialist billing company converts that guesswork into rules. Practices that outsource allergy and immunology billing to 247MBS typically see up to a 40% reduction in denials and recover roughly 90% of previously written-off claims, because the mixing log, the cap tracker, and the PA checklist run automatically rather than from memory. It also removes the staffing risk of a single biller who leaves in the middle of a Blue Cross Complete audit.
Whether you are a solo allergist in Ann Arbor or a multi-site group across metro Detroit, we run the full revenue cycle: eligibility and benefit checks, prior authorization for biologics, charge capture reconciled to the mixing log, coding and scrubbing, claim submission, payment posting, denial management, and patient statements. Our complete allergy and immunology billing overview explains the national methodology, our prior authorization service handles the buy-and-bill gatekeeping, and our denial management team works every MHP redetermination inside the MOAHR window. You keep clinical control; we own the paperwork that turns visits into deposits.
We bill for allergy and immunology practices statewide — from Detroit, Warren, and Grand Rapids to Ann Arbor, Lansing, and Flint, and out to Upper Peninsula clinics on UP Health and McLaren footprints. Our clients include solo private practices, multi-provider allergy groups, ENT-allergy combined offices, pediatric allergy programs, and hospital-affiliated immunology clinics. Each gets the same unit-level scrutiny on antigen and immunotherapy claims regardless of size or location.
Onboarding takes days, not months. We start with a revenue review of recent allergy and immunology claims to find undercounted 95165 doses, mistracked skin-test caps, and missed biologic authorizations. From there we map your top Michigan payers — MDHHS and your dominant MHPs — to their antigen and immunotherapy policies, connect to your EHR/PM system, and assign your dedicated account manager. You are live with full dashboard visibility inside the first billing cycle.
Your antigen doses, immunotherapy build-up, and biologic infusions turn into deposits when the units are counted right and authorizations are locked before the vial ships — and that is exactly what our medical billing for allergy and immunology in Michigan does day in and day out. We reconcile every dose to the mixing log, hold skin-test counts under each plan's annual cap, and clear buy-and-bill approvals across MDHHS fee-for-service and all nine Medicaid Health Plans before administration, then bill Priority Health, Blue Cross Complete, Medicare, and your commercial carriers on the same day. Detroit, Grand Rapids, and Ann Arbor practices routinely see A/R under 25 days and up to 40% fewer denials. Request a revenue review and we will show you the leakage on your last 90 days of claims.
Each city page covers the local payer mix, the practices we bill for there, and the denials we prevent.
These are the Michigan markets we cover in depth. We bill allergy practices right across the state — tell us where you are and we will walk you through billing in your area.
We reconcile every dose billed to the mixing log — one cc per dose, ten doses per vial under Medicare rules — so units never exceed what was prepared, which is the line MDHHS and the MHPs scrutinize most.
Yes. We secure prior authorization before the drug is purchased, bill the correct J-code units, and apply JW/JZ wastage modifiers so omalizumab, mepolizumab, and similar agents are reimbursed rather than written off.
All nine MHPs — Aetna, Blue Cross Complete, HAP CareSource, McLaren, Meridian, Molina, Priority, UnitedHealthcare, and UP Health — plus MDHHS fee-for-service, Medicare, and commercial carriers.
Michigan allows 120 days through MOAHR, but only after the plan's internal appeal is exhausted, so we file redeterminations early and cleanly rather than waiting for the deadline.
Yes, when the E/M is a distinct, separately identifiable service. We append modifier 25 only where the documentation supports it, which keeps same-day visits payable and audit-safe.
We flag experimental or non-covered testing before it is billed and issue an ABN so the balance moves to patient responsibility instead of becoming a write-off.
Whether you are a solo practice or a multi-site group, we bill Allergy & Immunology across Michigan under one dedicated account manager and a live dashboard — and treat every counted unit, authorization and appeal as recoverable revenue until it is safely paid.
