Official Description

Professional services for the supervision of preparation and provision of antigens for allergen immunotherapy (specify number of doses); 2 single stinging insect venoms

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 95146 refers to the professional services involved in the supervision of the preparation and provision of antigens specifically for allergen immunotherapy, focusing on two single stinging insect venoms. This procedure is typically performed by an allergist or a qualified healthcare provider who is responsible for preparing or overseeing the preparation of multiple dose vials containing the necessary antigens derived from stinging insects. These antigens are crucial for patients undergoing allergen immunotherapy, as they help in desensitizing the immune system to specific allergens. The preparation process is guided by the results obtained from allergy testing services, which are reported separately. Based on these results, the appropriate dosage of the stinging insect allergens is formulated and packaged into multiple dose vials, each designed to provide a specific number of injections. The allergist usually administers the initial dose of the antigen to the patient, monitoring for any adverse reactions, while subsequent doses are administered by another healthcare provider using the prepared vials. This structured approach ensures that patients receive the correct formulation and dosage necessary for effective immunotherapy, with the allergist reporting a single code for each multiple dose vial supplied. For different quantities of stinging insect venoms, specific codes are designated, allowing for accurate billing and documentation of the services rendered.

1. Indications

The procedure associated with CPT® Code 95146 is indicated for patients who have been diagnosed with allergies to stinging insect venoms. The following conditions may warrant the use of this procedure:

  • Allergic Reactions to Stinging Insects Patients who experience severe allergic reactions, such as anaphylaxis, following stings from specific insects, including bees, wasps, or hornets.
  • Desensitization Therapy Individuals who require allergen immunotherapy to reduce their sensitivity to stinging insect venoms, thereby decreasing the risk of future allergic reactions.

2. Procedure

The procedure for CPT® Code 95146 involves several key steps that ensure the safe and effective preparation of antigens for allergen immunotherapy:

  • Step 1: Allergy Testing Prior to the preparation of antigens, the patient undergoes allergy testing to identify specific sensitivities to stinging insect venoms. This testing is crucial as it provides the necessary data to formulate the appropriate antigen doses.
  • Step 2: Preparation of Antigens Based on the results of the allergy testing, the allergist or qualified healthcare provider prepares multiple dose vials containing the formulated antigens for the identified stinging insect venoms. This preparation is done under strict supervision to ensure accuracy and safety.
  • Step 3: Administration of Initial Dose The allergist typically administers the first dose of the antigen to the patient in a controlled environment, monitoring for any immediate adverse reactions. This step is critical for patient safety and is reported separately from the preparation services.
  • Step 4: Provision of Multiple Dose Vials After the initial dose, the patient is provided with the multiple dose vials containing the remaining doses of the antigens. These vials are intended for subsequent administration by another healthcare provider, ensuring that the patient continues their immunotherapy regimen as prescribed.

3. Post-Procedure

Following the procedure associated with CPT® Code 95146, patients are typically advised to monitor for any delayed allergic reactions after receiving the initial dose. It is essential for patients to follow the prescribed schedule for administering the remaining doses from the multiple dose vials. The healthcare provider may provide specific instructions regarding storage and handling of the vials to maintain the integrity of the antigens. Regular follow-up appointments may be scheduled to assess the patient's response to the immunotherapy and to make any necessary adjustments to the treatment plan.

76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
25 Significant, separately identifiable evaluation and management service by the same physician or other qualified health care professional on the same day of the procedure or other service: it may be necessary to indicate that on the day a procedure or service identified by a cpt code was performed, the patient's condition required a significant, separately identifiable e/m service above and beyond the other service provided or beyond the usual preoperative and postoperative care associated with the procedure that was performed. a significant, separately identifiable e/m service is defined or substantiated by documentation that satisfies the relevant criteria for the respective e/m service to be reported (see evaluation and management services guidelines for instructions on determining level of e/m service). the e/m service may be prompted by the symptom or condition for which the procedure and/or service was provided. as such, different diagnoses are not required for reporting of the e/m services on the same date. this circumstance may be reported by adding modifier 25 to the appropriate level of e/m service. note: this modifier is not used to report an e/m service that resulted in a decision to perform surgery. see modifier 57 for significant, separately identifiable non-e/m services, see modifier 59.
95 Synchronous telemedicine service rendered via a real-time interactive audio and video telecommunications system: synchronous telemedicine service is defined as a real-time interaction between a physician or other qualified health care professional and a patient who is located at a distant site from the physician or other qualified health care professional. the totality of the communication of information exchanged between the physician or other qualified health care professional and the patient during the course of the synchronous telemedicine service must be of an amount and nature that would be sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction. modifier 95 may only be appended to the services listed in appendix p. appendix p is the list of cpt codes for services that are typically performed face-to-face, but may be rendered via a real-time (synchronous) interactive audio and video telecommunications system.
