Allergy & Immunology billing · Greeley, CO
Allergy and immunology billing services in Greeley have to fit the practice, not the other way around.
A Weld County allergy clinic serving farm and feedlot country, a fast-growing Latino community, and a heavy Health First Colorado (the state's Medicaid program) panel bills a very different mix than a downtown metro group — and the biller who ignores that difference leaves money on the table. At 247 Medical Billing Services we start with the practices we serve in Greeley, then build the unit counting, buy-and-bill routing, and prior-authorization workflow around each one. This page lays out who we bill for, how a Greeley allergy claim gets paid, and why the specialty punishes a generalist.
We bill for the full range of Greeley allergy providers: solo and group allergists and immunologists, combined pediatric and adult practices, high-volume skin-testing and shot clinics, immunotherapy clinics billing incident-to, severe-asthma and biologic infusion programs, and food-allergy and oral immunotherapy (OIT) programs. Because Weld County carries a large Medicaid and pediatric population, many local practices run heavy volumes of environmental immunotherapy and pediatric skin testing, where per-test unit counting and RAE authorization rules drive the collections. A shot clinic dosing dozens of patients a day has a different exposure than a biologic infusion program managing a handful of thirty-thousand-dollar-a-year drugs, and we staff each accordingly.
Clients use us either as a full revenue cycle partner or for a single gap: eligibility and benefit verification, prior-authorization management for biologics, denial management and appeals, medical coding review, and end-to-end revenue cycle management. However you engage us, the allergy expertise behind the work is the same.
The practice mix in Greeley matters more than it does in a wealthier metro because margins here are thinner and the payer rules are stricter. A pediatric-heavy immunotherapy clinic collecting mostly from Health First Colorado cannot absorb a season of underpaid skin panels the way a commercially insured group might; every unit counted correctly is the difference between a sustainable schedule and one that runs at a loss. That is why our first move with a new Greeley client is a claim-level review of how testing units, antigen doses, and administration lines are actually being reported today, so we can show the practice where its current billing quietly costs it money before we change a thing.
| Service | Code | How it pays in Greeley |
|---|---|---|
| Antigen prep, multidose vial | 95165 | Per dose from mixing log; 10 billable doses/vial for Medicare (Novitas JH); most-audited line |
| Percutaneous (prick) tests | 95004 | Per individual test; units = number of tests, inside cap/MUE |
| Intradermal tests | 95024 | Per individual test; counted separately from prick units |
| Injection, single | 95115 | One injection only; not the two-plus code |
| Injection, two or more | 95117 | Billed once per visit, never multiplied by stick count |
| Biologic (severe asthma / urticaria) | HCPCS J-code | Buy-and-bill; exact unit math; medical vs pharmacy routing |
| Discarded single-dose vial | JW / JZ | JW for wastage, JZ for none; required on single-dose biologics |
| Same-day distinct E/M | Modifier 25 | Only on a documented, distinct problem visit |
The codes live in the claim, never in prose. What drives Greeley collections is unit counting and buy-and-bill, not the office visit. Skin and intradermal testing is reported per individual test, with units set to the number of tests and held inside each payer's annual cap and MUE — never collapsed into a single panel unit, which quietly underpays a large pediatric workup. Antigen preparation is billed from the mixing log at one cc per dose, ten billable doses per multidose vial for Medicare, and venom immunotherapy is counted by the number of venoms.
Prep and administration are two separate services, and treating them as one costs money. The antigen-preparation code and the injection-administration code bill independently; the administration line is reported once for two-or-more injections rather than multiplied per stick; and the antigen line is only billed when the practice actually prepared the vial. In a high-volume Greeley shot clinic running incident-to injections, those distinctions have to be enforced on every encounter — and when the physician is off the floor, the supervision rules shift again, which a claim built on habit will miss.
Greeley's Medicaid-heavy, pediatric-heavy panel also raises the stakes on eligibility and authorization. Coverage churn in a working-family and immigrant population is real: a patient enrolled in Health First Colorado in one quarter may not be in the next, and immunotherapy is a multi-year relationship with the payer, not a one-time visit. Miss a coverage change midway through a shot schedule and a paying patient becomes a write-off. We re-verify rather than assume, and we secure RAE prior authorization where the program requires it before the service is rendered.
There is also a documentation dimension that a generalist biller rarely enforces. Skin-testing results, the mixing log, the wastage record on single-dose biologics, and the note supporting any same-day problem visit all have to line up, because that is precisely the paper trail Novitas and Medicaid reviewers request when they pull an allergy chart. Modifier 25 is the clearest example: it belongs only on a genuinely distinct, documented E/M performed the same day as a shot, never on the routine injection, and the note has to prove the separate service. Attach it reflexively and you draw a flag; leave it off when a real problem visit happened and you forfeit a legitimate service. We work the front of the cycle so the documentation and the claim tell one consistent story, rather than reconstructing records after a denial or an audit letter lands.

Biologics are where a Greeley practice wins or loses the most per patient. A severe-asthma or chronic-urticaria agent past thirty thousand dollars a year has to clear three gates every time: exact HCPCS unit math, the JW or JZ discarded-drug modifier on single-dose vials, and a prior authorization confirmed before the drug is drawn up. Miss the authorization and the practice eats the vial; miss the wastage modifier and the payer claws back the difference. We treat each buy-and-bill administration as a financial event that clears those gates before it happens.

Practices choose to outsource allergy and immunology billing in Greeley once they weigh a single mishandled antigen season — recoupment plus the False Claims Act exposure that rides on clinical-judgment dosing — against a billing fee. As your billing company we take the mixing logs, the verification queue, and the biologic authorization workload off a stretched front desk and run them with allergy-trained staff. That is not what a general billing services company delivers when it treats an allergy claim like a routine office visit.
We verify benefits and secure prior authorization on every biologic before administration, route buy-and-bill drugs to the correct medical or pharmacy benefit, screen non-covered testing such as large IgG food-sensitivity panels to an ABN or patient-pay path before it reaches a payer, and reconcile antigen doses against the log weekly. You get a dedicated account manager who knows Novitas JH timelines and Health First Colorado and RAE rules, plus a free 360-degree dashboard covering days in A/R, first-pass rate, and denial recovery. As a professional medical billing services company operating since 2005, we are HIPAA and SOC 2 Type II compliant, staff AAPC- and AHIMA-credentialed coders, and belong to HBMA. Our compliant targets: a 99% first-pass clean-claim rate, roughly 99% net collection, days in A/R under 25, up to 40% fewer denials, up to 90% recovery on worked denials, 24-hour claim submission, and 98% client retention.

We bill antigen prep from the mixing log at one cc per dose, hold to ten billable doses per multidose vial for Medicare, and reconcile weekly. Over-units and clinical-judgment dosing are the top recoupment risk in the specialty.
Yes. We confirm prior authorization before administration, apply JW/JZ correctly on single-dose vials, get the HCPCS unit math exact, and route the drug to the right benefit.
Usually. One denied biologic or mis-billed antigen season costs more than a year of billing support, and it frees your staff from the verification and authorization grind.
