Allergy and Immunology Billing Services in Texas

Texas runs one of the most complex primary-care payer mixes in the nation, and for an allergy practice that complexity lands squarely on the two lines that decide the month: the counted antigen dose and the buy-and-bill biologic. Nearly four million residents are enrolled through HHSC, delivered across STAR, STAR+PLUS, and STAR Kids managed care plus fee-for-service. An allergist in Houston may bill Superior, Amerigroup, Community First, Molina, UnitedHealthcare, and BCBS TX in a single week — each with its own drug prior-authorization portal, its own immunotherapy dose cap, and its own white-bag-versus-buy-and-bill stance.

The practical result is that a Texas allergy practice faces both a drug-authorization gate and a unit-counting maze at the same time. TMHP and each STAR-program MCO apply their own step-therapy and prior-authorization rules to biologics, cap immunotherapy doses differently, and adjudicate the 95165 antigen line against the federal dose definition. We build those payer rules and the mixing-log dose count into the front end of the revenue cycle, so claims go out correctly the first time instead of coming back as a recoupment months later.

Allergy reimbursement in Texas turns on counting the dose, splitting the service, and clearing the drug authorization — not on the office visit. Testing is reported per individual test against a payer cap; antigen preparation is billed from the mixing log; the injection is a separate line from the extract; and biologics pay only when the HCPCS math, the wastage modifier, and the prior authorization all line up.

We code these against each Texas payer's edits — the STAR-program MCOs, TMHP fee-for-service, Medicare, and commercial — so the antigen dose, the per-test skin panel, and every biologic line survive adjudication instead of being downcoded or bundled away.

Texas allergy practices outsource billing because the specialty's whole margin hides inside rules a general biller almost never touches. The 95165 dose definition, the ten-doses-per-vial Medicare cap, the per-test skin count, the prep-versus-administration split, venom-by-venom coding, and JW/JZ wastage on five-figure biologics do not transfer from an E/M-heavy book of business — and each STAR, STAR+PLUS, and STAR Kids MCO layers its own drug authorization on top. Keeping one in-house desk current on all of that, through turnover and rule changes, puts the highest-dollar claims in the practice at risk the week that person is out.

Outsourcing to a specialist billing company converts that fixed overhead and single point of failure into a predictable, performance-tied cost with a whole certified team behind your claims. When you outsource the revenue cycle to 247MBS, eligibility, antigen-dose counting, coding, biologic authorization, denial work, and A/R follow-up all run without gaps. For a solo allergist in Austin or a growing group in San Antonio, professional outsourcing is often the difference between a billing function that merely drops claims and one that actively defends the margin on every vial.

We bill for allergy and immunology practices statewide, from the major metros to the border and rural regions:

Solo allergists, multi-provider immunology groups, immunotherapy and shot clinics, severe-asthma biologic programs, and food-allergy or oral-immunotherapy practices all run on the same disciplined process, tuned to their region's payer mix.
