Allergy & Immunology billing · Vallejo, CA
247 Medical Billing Services provides allergy and immunology billing services for Vallejo practices that keep skin testing, antigen preparation, immunotherapy, and biologic buy-and-bill paid in a Solano County market where Medi-Cal drives much of the volume.
Vallejo allergists sit in the North Bay between Sutter Solano Medical Center and Kaiser Permanente Vallejo, serving a working-class Mare Island and waterfront population where Partnership HealthPlan of California administers Medi-Cal managed care under DHCS and CalAIM, alongside Medicare on Noridian JE and a smaller commercial book. Billing accurately in that mix depends entirely on unit counting and antigen-line discipline.
Before the coding, it helps to know your practice model, because the payer rules bite differently for each one.
We bill for solo and group allergists across Solano County, pediatric and adult allergy practices carrying heavy Partnership HealthPlan Medi-Cal panels, high-volume skin-testing and shot clinics, immunotherapy programs billing incident-to, severe-asthma and biologic infusion programs, and food-allergy and OIT clinics. A pediatric practice serving a largely Medi-Cal Vallejo population needs antigen caps and CalAIM documentation handled precisely; a shot clinic needs injection-administration accuracy; a biologic program needs prior authorization confirmed before a single dose is drawn. As an allergy and immunology billing services provider in Vallejo, we apply the right rule set to each model rather than forcing one template on all of them.
Reimbursement here is decided by units and by which vial was prepared, not by the office visit. The table maps each service from encounter to deposit.
| Service | Code | How it is billed in Vallejo | What drives payment |
|---|---|---|---|
| Percutaneous skin testing | 95004 | One unit per individual test, up to the annual cap/MUE | Unit count matched to number of tests |
| Intradermal testing | 95024 | Per individual test performed | Documented count inside Partnership/commercial caps |
| Antigen preparation, multidose vial | 95165 | One unit per prepared 1 cc dose, ten billable doses per vial for Medicare | Mixing log governs units |
| Injection, single allergen | 95115 | One injection encounter | Prep billed separately only if vial prepared |
| Injection, two or more | 95117 | Billed once regardless of shot count | Never multiplied |
| Biologic administration + drug | J-code + admin | Buy-and-bill, exact HCPCS units, JW/JZ on single-dose vials | Prior auth before administration |
| Same-day E/M with procedure | Modifier 25 | Only on a distinct documented problem | Separate documentation |
Solano County's Medi-Cal book runs almost entirely through Partnership HealthPlan of California, which applies its own antigen caps, testing edits, and CalAIM documentation expectations that a commercial-trained biller will not know. Because Vallejo skews more Medi-Cal and retiree than the affluent suburbs to its south, a practice cannot lean on high commercial reimbursement to cover coding mistakes; margin comes from capturing every legitimate testing unit and defending the antigen line. Medical billing for allergy and immunology in Vallejo therefore lives or dies on Partnership HealthPlan fluency plus clean Noridian Medicare handling for the retiree segment near Glen Cove and Mare Island. We reconcile every Partnership remittance against the units we submitted, so an antigen line that pays short is flagged and appealed instead of quietly written off, and we watch CalAIM policy updates that change how testing and immunotherapy are documented for Solano County members. That vigilance is where a specialty billing company earns its keep in a low-margin, Medi-Cal-weighted market.

Certified AAPC and AHIMA coders read your mixing logs and testing sheets, apply the Partnership HealthPlan and Noridian edits, and keep a clean audit trail on the antigen line so a records request never becomes a recoupment. Every client gets a dedicated account manager and a free 360-degree dashboard showing first-pass rate, denials, and days in A/R in real time. This is professional revenue cycle work, which is why Solano County practices treat us as their allergy and immunology billing company rather than a clearinghouse. When you outsource allergy and immunology billing in Vallejo to us, the same rules are enforced on every claim, every day.
From a single-provider immunology office to a multi-site group running biologic infusions, the workflow scales to your Medi-Cal-heavy payer mix and testing volume. Outsourcing that work means eligibility, coding, submission, denials, and A/R move as one connected process, so a biologic authorization and its downstream claim never drift apart. Food-allergy and OIT programs get non-covered-service screening up front, so families are not surprised and the practice is not stuck holding an uncollectible balance.
Finding an in-house biller who understands antigen dosing, Partnership HealthPlan rules, and biologic buy-and-bill is hard in the North Bay. As a medical billing services company built for specialty revenue cycle, we deliver a 99% first-pass clean-claim rate, roughly 99% net collection, days in A/R under 25, up to 40% fewer denials, and up to 90% denial recovery on worked accounts. Claims submit within 24 hours, we hold 98% client retention, and we have run specialty billing since 2005, more than 20 years, under HIPAA and SOC 2 Type II controls as an HBMA member. Allergy and immunology billing services outsourcing in Vallejo frees your clinicians to see patients while a professional billing services company owns collections. We connect eligibility verification, prior authorization, denial management, medical coding, and revenue cycle management into one workflow so nothing slips between steps.
Medical billing for allergy and immunology in Vallejo protects a thin North Bay margin only when every testing unit is captured and every antigen line survives a Partnership HealthPlan review. We run the full revenue cycle for Solano County allergists - eligibility, prior authorization, per-test skin coding, immunotherapy prep, payment posting, and appeals - built around the Medi-Cal managed care that Partnership HealthPlan of California administers under DHCS and CalAIM, plus clean Noridian JE handling for the retiree population near Glen Cove and Mare Island. Practices around Sutter Solano Medical Center and Kaiser Permanente Vallejo see short-paid antigen lines flagged and appealed instead of written off.
