Challenges

What slows reimbursement

The common friction points that trigger delays, denials, and rework.

Key challenges
  • Accurately coding for allergy testing, distinguishing between percutaneous (prick) and intradermal tests.
  • Billing for the preparation of allergy extracts (antigens) for immunotherapy.
  • Managing the complex billing for immunotherapy injections (shot visits) over a long period.
  • Ensuring proper coding for the number of vials and doses administered.
  • Navigating payer policies for covered vs. non-covered tests and treatment.
Our solutions
  • Certified allergy coders with specialized knowledge of CPT and HCPCS coding for allergy services.
  • Precise coding for all allergy testing, including percutaneous (95004), intradermal (95017, 95018), and patch tests.
  • Expertise in billing for the preparation of antigen vials (95144-95170) based on the number of doses.
  • Meticulous management of immunotherapy injection billing, tracking patient visits and doses.
  • Proactive verification of insurance benefits for allergy testing and treatment.
  • Detailed support for coding for pulmonary function tests and other related diagnostics.

Coding

Coding complexities we watch closely

Modifier usage, documentation rules, and specialty-specific payer edits.

Complexity checklist
  • Allergy testing coding based on the number of tests and method (percutaneous vs. intradermal).
  • Antigen preparation coding based on the number of doses and whether it's a single or multiple antigens.
  • Immunotherapy injection coding based on the number of injections per visit.
  • Distinguishing between professional and technical components for testing interpretation.
Denial triggers

Incorrect coding for the number of allergy tests performed.

Billing for testing or treatment that is not a covered benefit.

Unbundling of antigen preparation codes.

Incorrect coding for immunotherapy injection visits (e.g., using an E&M code instead of injection code).

Lack of medical necessity for testing based on patient history.
