Allergy & Immunology billing · Santa Clara, CA
Allergy and immunology billing services in Santa Clara demand a partner who understands that your revenue is decided at the mixing bench and the infusion chair, not at the front desk.
247 Medical Billing Services has run allergy revenue cycles since 2005, and we know that a Santa Clara practice sitting in the middle of Silicon Valley faces a payer mix unlike anywhere else in California: a wall of commercial HMO and PPO plans tied to large technology employers, alongside a steady stream of Santa Clara Family Health Plan and Medi-Cal managed care members. Getting paid here means counting units correctly, splitting antigen prep from administration, and clearing prior authorization on biologics before a single dose is drawn.
The commercial skew in the South Bay changes how you get paid. Silicon Valley employer plans route immunotherapy and biologics through medical-versus-pharmacy benefit rules that shift plan to plan, so a verification of benefits step that confirms the correct benefit lane before administration is the difference between a clean pay and a five-figure write-off. On the public side, Medi-Cal managed care under CalAIM adds its own prior-authorization and site-of-care requirements, and Santa Clara Family Health Plan handles a large share of the county's Medicaid lives with rules that do not mirror commercial payers.
California allergists also bill under Noridian as the Part B Medicare Administrative Contractor for Jurisdiction E, and Noridian's coverage articles on allergy testing and immunotherapy set unit caps that a national billing services company operating out of state routinely misses. We build every Santa Clara claim to those local rules first. Because a large share of South Bay patients carry high-deductible commercial coverage, we also run eligibility up front so patients understand their share before testing, which protects both collections and your Google reputation.
Antigen preparation is where the specialty makes or loses money. The single antigen-prep unit is billed from the mixing log, one cubic centimeter per dose, and dosing built on clinical judgment rather than the log is the most-audited pattern in allergy. We reconcile every prepared vial to the record before the claim goes out.
Each service line has to be counted and sequenced correctly. This is the core logic our coders apply to a South Bay allergy encounter.
| Service | Code | How it is counted in Santa Clara | Who typically pays |
|---|---|---|---|
| Percutaneous skin testing | 95004 | Per individual test; units equal the number of tests, capped to payer MUE | Commercial HMO/PPO, Medi-Cal MCO |
| Intradermal testing | 95024 | Per individual test, not a single panel unit | Commercial, Medicare |
| Antigen preparation, single/multi | 95165 | One unit per prepared dose from the mixing log; 10 billable doses per multidose vial for Medicare | Medicare, commercial |
| Allergen immunotherapy injection(s) | 95117 | Billed once for two or more injections, never multiplied | All payers |
| Biologic administration | 96372 / 96401 | Paired with the drug HCPCS and correct route | Medical benefit, VOB-confirmed |
| Severe-asthma biologic (drug) | J-code + JW/JZ | Exact unit math; JW/JZ on single-dose vial waste | Commercial, Medicare |
| Same-day distinct E/M | 99213-25 | Modifier 25 only on a separately documented visit | All payers |
Allergy denials cluster around a handful of predictable errors. We work them before submission, not after the money is already gone.

We bill for solo and group allergists and immunologists across Santa Clara County, pediatric and adult allergy practices near El Camino and Valley Med, high-volume skin-testing and shot clinics running immunotherapy incident-to a supervising physician, severe-asthma and chronic-urticaria biologic programs, and food-allergy and oral-immunotherapy clinics serving the South Bay's younger, employer-insured families.

Hiring and holding a certified allergy coder in one of the most expensive labor markets in the country is a losing battle for most practices.

As your medical billing services company, we bring a 99% first-pass clean-claim rate, roughly 99% net collection, days in A/R held under 25, and 24-hour claim submission, all under HIPAA and SOC 2 Type II controls and HBMA membership.

We have kept a 98% client retention rate for 20-plus years because practices stay when the money shows up predictably. Choosing an allergy and immunology billing services provider in Santa Clara that already knows Noridian and Medi-Cal managed care means no ramp-up on the rules that matter most.
