95115
Professional services for allergen immunotherapy; single injection
CPT code 95115 describes the professional services provided during the administration of a single allergen immunotherapy injection. This procedure, commonly known as an 'allergy shot,' is a long-term treatment approach aimed at reducing sensitivity to allergens that trigger symptoms like allergic rhinitis, conjunctivitis, or asthma. The service includes the clinical supervision of the patient, the physical administration of the allergenic extract by a qualified healthcare professional, and the required post-injection monitoring period. It is important to distinguish this code from the codes used for the provision of the allergenic extract itself (95144-95170), as 95115 strictly covers the administration component. Before the injection is given, the clinician must perform a brief assessment of the patient’s current health status to ensure there are no contraindications, such as a recent asthma flare or illness. The injection is typically administered subcutaneously into the posterior aspect of the upper arm. A critical component of the 95115 service is the 30-minute mandatory observation period following the injection. This period is necessary to monitor the patient for potential systemic reactions, including life-threatening anaphylaxis, which requires immediate medical intervention. Documentation must include the specific allergen dose, the location of the injection site, the patient's reaction to the previous dose, and their stability during the observation period. If more than one injection is administered during the same clinical encounter, 95117 should be reported instead of 95115.
Clinical Indications
- Allergic rhinitis (seasonal or perennial)
- Allergic conjunctivitis
- Allergic asthma
- Hypersensitivity to stinging insect venom (bees, wasps, hornets)
- Hypersensitivity to aeroallergens such as pollen, mold, dust mites, or animal dander
- Prevention of systemic allergic reactions
Procedure Steps
- Verify the patient identity and cross-reference with the specific immunotherapy treatment schedule.
- Assess the patient for current respiratory symptoms or general illness that might necessitate delaying the injection.
- Inspect the injection site for any lingering reactions from previous treatments.
- Prepare the prescribed dose of allergenic extract using a sterile allergy syringe.
- Clean the injection site (usually the posterior upper arm) with an antiseptic swab.
- Administer the extract subcutaneously at a 45 to 90-degree angle.
- Discard the used syringe and needle in a designated sharps container.
- Instruct the patient to remain in the clinic for at least 30 minutes for observation.
- Monitor the patient for local wheal-and-flare reactions or systemic signs of anaphylaxis.
- Document the dosage, site, batch number, and patient tolerance in the medical record.
Coding Guidelines
- Do not report 95115 in conjunction with 95117 for the same encounter.
- 95115 is used for a single injection only; 95117 is used for two or more injections.
- The provision of the allergenic extract is not included in 95115 and must be reported separately using codes 95144-95170.
- Evaluation and Management (E/M) services should not be reported with 95115 unless a significant, separately identifiable service is performed, in which case modifier 25 is required.
- The 30-minute observation period is considered part of the 95115 service and is not billed separately.
- If the physician only provides the extract and does not supervise the injection, 95115 should not be billed.
