How do you read a skin test record?

If there is no reaction with a wheal and flare, the test is read as negative and being allergic is very unlikely. If the skin test is positive, it implies that the patient has a type of antibody (IgE) on specialized cells in the skin that release histamine to cause symptoms of an allergic reaction.

How do you read wheal and flare allergy test results?

Your testing sheet will indicate the size of the wheal and the size of the flare, both of which are used in interpreting the reaction. The wheal is the raised area of skin. The flare is the red area of skin surrounding the wheal. For example, a result of 5/15 for alder tree doesn't mean 5 out of 25.

How do allergy shots work?

Administering allergy immunotherapy, commonly known as “allergy shots,” can be performed in a variety of ways. Some allergy practices give the patients the serum vials to bring to their primary care physician (PCP) to administer the shots according to the treatment plan. Some providers let the patients self-administer the shots, while other allergists say they consider patient self-administration to be unsafe.#N#When the provider who makes up the serum is also the administer of the allergy shots, the provider may make up the sequentially diluted serum sets that are specific to the patient and then administer first from the most diluted vial, moving on to the next most diluted vial, and eventually up to the maintenance vial. Although each vial may have been billed based on 1 cc doses, the doses given to the patient may be 0.5 cc doses, which means a vial can last for 20 doses. The payer pays for the serum up front for 95145-95180 (and most often 95165), times the number of units billed. Then, the practice bills one of the two injection codes.#N#Some antigens do not mix with other antigens and must be diluted in separate vials. The number of vials determines the number of shots the patient receives. The two possible injection codes for administering immunotherapy are:#N#95115 Professional services for allergen immunotherapy not including provision of allergenic extracts; single injection#N#95117 2 or more injections#N#Note that 95117 is not an add-on code: Do not report 95115 with 95117; one or the other is coded, not both.#N#Some doctors prepare their serum for immunotherapy “off the board.” Using this technique, the technician works with the formula and has a board of all the different antigens. She draws up into the syringe a specific amount of antigen A, a specific amount of antigen B, and a specific amount of dilution per a formula for the patient, and then administers the shot. Although 95120 Professional services for allergen immunotherapy in the office or institution of the prescribing physician or other qualified health care professional, including provision of allergenic extract; single injection and 95125 Professional services for allergen immunotherapy in the office or institution of the prescribing physician or other qualified health care professional, including provision of allergenic extract; 2 or more injections) (or 95130-95134 for venoms are the codes that most reflect what is done when allergy immunotherapy is performed “off the board,” no payers process claims using these more appropriate codes. As a result, the practice still must bill as if they make up pre-made vials and then administer the shots, using 95145-95180 (most often 95165) and 95115 or 95117.#N#Finally, there are providers who make up maintenance dose vial sets and then use an “off the board” process, diluting the patient’s full maintenance dose with the appropriate dilutant when preparing the immunotherapy. These services also must be coded using 95145-95180 (95165, most often), plus the shot administration using 95115 or 95117.

What is the first step in allergy immunotherapy?

The first step in the allergy immunotherapy process is allergy testing. Typically, this is performed by medical assistants, nurses, nurse allergists (specialty certification in nursing), and other non-physician providers. You may think these ancillary staff and non-physician providers are working and billing under the incident-to rules, but their services actually fall under the diagnostic services supervision rules, which require the practice to provide them with either “general,” “direct,” or “personal” supervision. Although these levels of supervision are the same as described in incident-to services, a different set of rules apply to diagnostic services. Each diagnostic CPT® code is assigned a supervision level requirement in the Medicare Physician Fee Schedule (MPFS) database depending on the perceived risk of the procedure.#N#General supervision means the procedure is furnished under the physician’s overall direction and control, but the physician’s presence is not required. Under general supervision, the training of the non-physician personnel who perform the diagnostic procedure and the maintenance of the necessary equipment and supplies is the continuing responsibility of the physician.#N#Direct supervision means the physician must be present in the office suite and immediately available to furnish assistance and direction throughout the performance of the procedure. The physician does not have to be present in the room where the procedure or service is performed. Direct supervision guidelines for diagnostic testing and incident-to services are the same, but not all diagnostic procedures call for direct supervision.#N#Personal supervision means the physician must be in the room during the performance of the procedure. This is required for diagnostic procedures that pose the highest risk to the patient.#N#The MPFS database carries a “1” in the Diagnostic Supervision field if the code only needs general supervision, a “2” if the code requires direct supervision, and a “3” if the code requires personal supervision. If the field carries a “9,” the supervision concept does not apply.#N#Common allergy testing codes that require direct supervision are:#N#95004 Percutaneous tests (scratch, puncture, prick) with allergenic extracts, immediate type reaction, including test interpretation and report by a physician, specify number of tests#N#95024 Intracutaneous (intradermal) tests with allergenic extracts, immediate type reaction, including test interpretation and report by a physician, specify number of tests#N#95027 Intracutaneous (intradermal) tests, sequential and incremental, with allergenic extracts for airborne allergens, immediate type reaction, including test interpretation and report by a physician, specify number of tests#N#95028 Intracutaneous (intradermal) tests with allergenic extracts, delayed type reaction, including reading, specify number of tests#N#95044 Patch or application test (s) (specify number of tests)#N#95052 Photo patch test (s) (specify number of tests)#N#95056 Photo tests#N#High-risk codes requiring personal supervision are:#N#95060 Ophthalmic mucous membrane tests#N#95070 Inhalation bronchial challenge testing (not including necessary pulmonary function tests); with histamine, methacholine, or similar compounds#N#95071 with antigens or gases, specify#N#The concept of diagnostic testing supervision does not exist, as reflected by a “9” in this field in the MPFS, because neither the provision of the allergy serum nor the allergy shots are diagnostic. Instead, these services fall under the rules of incident-to services and, therefore, require direct supervision if performed by someone other than the physician.
