Where allergy & immunology practices lose revenue?
Same-Day Testing & Treatment
Up to 22% of same-day allergy claims are rejected due to CPT coding conflicts and missing modifiers — particularly when testing and treatment services are billed together in a single encounter without proper modifier 25 or 59 documentation.
Immunotherapy CPT Coding Precision
Allergy immunotherapy billing requires distinct codes for extract preparation (95144–95170), single-dose injections (95115), multiple-dose injections (95117), and cluster or rush protocols — each with separate documentation and unit requirements that vary by payer contract.
Biologic Prior Authorization Burden
Dupixent, Xolair, Fasenra, and Nucala require intensive pre-authorization documentation including step therapy failures, IgE levels, and diagnosis confirmation — with renewal cycles that create ongoing authorization management demands throughout the treatment lifecycle.
Recurring Injection Revenue Leakage
Recurring immunotherapy injections billed over months or years create compounding revenue risk, where missed vial preparation charges, incorrect dose billing, or underdocumented injection visits produce leakage that accumulates silently across the treatment course.
Modifier Misuse & Bundling Denials
NCCI edits that bundle allergy testing CPT codes require precise modifier sequencing (25, 59, XS) to prevent inappropriate bundling — and incorrect modifier application on high-volume allergy testing days generates cascading denials across multiple claims simultaneously.
Documentation & Medical Necessity Gaps
Allergy testing, immunotherapy, and biologic treatments all require specific documentation of allergens tested, dosage, administration method, and clinical justification — gaps at any stage trigger medical necessity denials that are costly to appeal and often preventable.
Full-Spectrum RCM for every allergy & immunology encounter
The following nine core services are included in AnnexMed’s standard RCM offering for allergy and immunology. Each is customized to allergy-specific payer rules, CPT and ICD-10 standards, and documentation requirements.
Eligibility & Benefits Verification
We confirm patient insurance coverage, deductibles, co-pays, and immunotherapy and biologic coverage limitations prior to every encounter, including testing session limits and in-network injection provider requirements and eligibility.
Prior Authorization Management
Our team manages the full prior auth lifecycle for biologic medications, extensive testing panels, and immunotherapy treatment plans — including submission, follow-up, clinical documentation support, and appeals for denied authorizations.
Claims Submission & Tracking
We submit clean claims electronically to all payers with modifier validation, same-day testing and treatment sequencing checks, and allergen count verification before each claim is released, preventing coding-related rejections at submission cycles quickly.
Denial Management & Appeals
Every denied allergy claim is reviewed for root cause — modifier error, bundling conflict, medical necessity gap, or documentation deficiency — and appealed with targeted clinical support and payer-specific documentation packages.
Accounts Receivable (AR) Follow-up
Our AR specialists proactively follow up on outstanding balances with payers to accelerate collections on recurring injection-based revenue and keep days in AR below industry benchmarks across your full allergy and immunology service mix.
Patient Statements & Collections
We manage the complete patient billing cycle for allergy services, from clear statements that explain testing and immunotherapy charges to respectful collection follow-ups, improving collections while preserving long-term patient relationships trust.
Payment Posting & Reconciliation
All insurance and patient payments are posted and reconciled daily against expected reimbursements — including biologic buy-and-bill reconciliation and recurring injection payment verification — keeping your books clean and audit-ready.
Provider Credentialing
We manage provider enrollment and credentialing with all commercial, Medicare, and Medicaid payers to keep your contracts active and ensure allergy and immunology services are consistently reimbursable without credentialing-related delays.
Reporting & Analytics Dashboard
You receive real-time RCM performance dashboards covering clean claim rates, denial patterns by service type, immunotherapy revenue tracking, biologic reimbursement accuracy, AR aging, and payer-specific trends — giving you full financial visibility.
Allergy & immunology-specific RCM services
Allergy Skin Testing
We review every testing encounter and apply correct CPT codes based on allergen count, testing method (percutaneous vs. intradermal), and reading type — covering the full range of skin testing codes with accurate antigen counts to maximize reimbursement within payer-specific testing limits.
Allergen Immunotherapy Billing
Immunotherapy billing requires distinct coding for extract preparation (95144–95170) and injection administration (95115, 95117), with documentation for single vs multi-dose protocols and cluster vs maintenance schedules. We ensure correct CPTs prevent bundling denials.
Biologic Prior Auth & Admin
We manage the full biologic authorization cycle for Dupixent, Xolair, Fasenra, and Nucala, including submission, step therapy documentation, IgE verification, and re-authorization. Buy-and-bill claims are coded with J-codes, NDCs, and waste documentation for full reimbursement.
Spirometry & PFT Billing
In-office spirometry and PFT services performed during allergy visits are coded as separately reimbursable services with appropriate modifiers to prevent bundling with the E&M visit — supported by pre- and post-bronchodilator documentation to meet payer medical necessity standards.
Patch Testing Billing
Patch testing claims are billed with accurate allergen counts, placement and reading documentation, and physician interpretation notes — supporting full reimbursement for this time-intensive diagnostic procedure from both commercial payers and Medicare.
Food & Drug Challenge Billing
Oral food and drug challenge procedures are coded using unlisted allergy procedure codes with physician supervision documentation, emergency preparedness notes, and clinical justification, ensuring payer reimbursement for high-complexity diagnostic services and submission outcomes.
E&M Coding Allergy MDM
Allergy and immunology visits involving multiple chronic conditions, diagnostic interpretation, and biologic therapy adjustments qualify for high-complexity MDM under 2021 AMA guidelines. Our certified coders assign E&M levels based on clinical decision-making for reimbursement.
ICD-10 Allergy Coding
Allergy and immunology diagnosis coding requires differentiation between allergic rhinitis (J30.x), contact dermatitis (L23.x), asthma (J45.x), and immunodeficiency disorders (D84.x). Certified coders apply specific diagnosis codes accurately across all conditions.
ImpactRCM.AI & ImpactBI.AI for allergy & immunology
AnnexMed’s proprietary AI platforms are configured for allergy and immunology-specific billing patterns, modifier logic, immunotherapy tracking, and performance benchmarking.
