AllergyIntolerance is a clinical FHIR Resource that acts as a record of a clinical assessment of an allergy or intolerance. Allergies and intolerances indicate a propensity (a potential risk to an individual) to have an adverse reaction on future exposure to the specified substance, such as medication or food.
Accessing a patient's allergies and intolerances can aid in workflows such as working with the patient to determine their medication protocol.
While some payers may make this information available, most do not have this data unless it is submitted to the payer by providers for quality measures or other provider/payer data exchange programs, as it is not included with or derived from core claims generation.
The full list of search parameters can be found here. Some of the most important are:
The ID of the patient who has the allergy or intolerance. We recommend using this search parameter along with the
The clinical status of the allergy or intolerance
Assertion about certainty associated with the propensity, or potential risk, of a reaction to the identified substance (including pharmaceutical product)
While some servers may support a resource-level search without any parameters, not all do. We recommend using the format below with the patient ID via the
$PATIENT_ID wildcard as a search parameter.
