All documentation must be maintained in the patient's medical record and made available to the contractor upon request; every page must be legible and include appropriate patient identification (e.g., complete name, dates of service).
The medical record must include the legible signature of the physician or non-physician practitioner responsible for and providing the care.
The medical record must support the selected ICD-10-CM code(s) and the submitted CPT/HCPCS code must accurately describe the service performed.
Prior to testing there must be evidence that a history was obtained indicating possible allergy and that attempts were made to narrow the area of investigation so that the minimal necessary skin tests were selected.

Allergy testing is covered when the medical record documents a history indicating the possible presence of allergy and the clinician selected a minimal number of tests/antigens based on patient-specific history and physician examination.
Allergy testing is covered when the medical record documents the test(s) used, the interpretation(s), and objective measurement of reaction size (wheal and erythema in mm) or a standardized in vivo grading system.
Allergy testing is covered when the patient has clinically significant allergic symptoms and conservative therapy has failed.
Allergy testing includes performance, evaluation, and reading of cutaneous and mucous membrane tests together with physician history (including immunologic history), physical examination, antigen selection, and interpretation of results.
Standard skin testing is the preferred method when allergy testing is necessary.
When a percutaneous or intracutaneous single test (CPT 95004 or 95024) and sequential/incremental tests (CPT 95017, 95018, 95027) are performed the same day, both code types may be reported only if they are for different allergens or for different dilutions of the same allergen.
