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.
RAST type tests are covered when medically necessary and supported by the related Local Coverage Determination (LCD) and current medical literature or standards of practice.
An ECG is covered when the result is relevant to the management, diagnosis, or treatment of the patient.
A separate ECG on the same day as a cardiac stress test is payable only when it provides additional clinically necessary information beyond the stress test (e.g., to rule out acute myocardial infarction prior to performing the stress test).
