PURPOSE
To establish a basis for determining medical necessity of testing and treatment for allergic individuals.
DESCRIPTION
Allergy or hypersensitivity disorders may be manifested by generalized systemic reactions as well as localized reactions in any organ system of the body. The reactions may be acute, subacute or chronic, immediate or delayed, and may be caused by numerous offending agents, (e.g., pollen, molds, dust, mites, animal dander, stinging insect venoms, foods and drugs).
The optimum management of the allergic individual should include a careful history and physical examination and may include confirming the cause of allergic reaction by information from some of the testing methods listed below. Once the agent is identified, treatment is provided by avoidance, medication or immunotherapy.
Immunotherapy involves regular injections of an offending allergen over a period of months, with the goal of reducing symptoms. It begins with low doses to prevent untoward reactions, with gradually increasing doses injected once or twice a week as immunity to the antigen develops. After the maintenance dose is achieved, the interval between injections may range between two and six weeks. Immunotherapy may be administered continuously for several years.
POLICY
BlueCross BlueShield of Tennessee recognizes the need for consistency in the determination of medical appropriateness for testing and treatment of allergies.
