Summary & Overview

CPT 95017: Allergy Skin Testing (Prick, Scratch, Intradermal, Venom)

CPT code 95017 denotes comprehensive allergy skin testing using any combination of scratch, puncture, prick, and intradermal techniques, performed sequentially and incrementally and including venom testing. This procedure is a core diagnostic tool in allergy and immunology, guiding clinical management for allergic rhinitis, insect venom hypersensitivity, food allergy evaluation, and other IgE-mediated conditions. Nationally, standardized reporting of this service supports clinical decision-making and affects outpatient allergy clinic workflows and billing practices.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what CPT code 95017 represents, the typical clinical and site-of-service context, and what to expect from payer coverage patterns. The publication summarizes benchmarks where available, highlights relevant policy considerations for outpatient allergy testing, and situates the code within clinical pathways for diagnostic allergy evaluation. Practical information on common modifiers, related codes, and documentation considerations is provided in separate sections. Data not available in the input will be noted where applicable.

Billing Code Overview

CPT code 95017 covers allergy testing performed using any combination of techniques, including scratch, puncture, prick, and intradermal tests, conducted in a sequential and incremental manner. The description explicitly includes testing for venoms.

Service type: Allergy diagnostic testing — skin testing for allergic sensitization using sequential/per-mutational methods.

Typical site of service: Outpatient clinic or office-based allergy/immunology setting, including physician offices or specialized allergy clinics where sequential skin testing is performed.

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult or pediatric patient presenting to an allergy clinic or outpatient otolaryngology/allergy-immunology practice with suspected IgE-mediated allergic disease after a history of seasonal rhinitis, recurrent urticaria, suspected venom allergy, or suspected medication/food allergy where skin testing is indicated. The clinical workflow begins with a focused history and physical exam, review of medications and antihistamine use, and selection of test panels. On the day of testing the patient is positioned in an exam chair; percutaneous (scratch, puncture, or prick) testing is performed first using incremental, sequential placement of extracts on the forearm or back. If needed, intradermal testing is performed subsequently for more sensitive detection (for example, to evaluate venom or drug sensitivities) using small-volume intradermal injections. Immediate readings are obtained at appropriate intervals (typically 15–20 minutes) and results documented with measurements of wheal and flare. Post-test counseling, avoidance measures, and interpretation are provided; if a systemic reaction occurs, emergency treatment is available on site. Billing for this service uses 95017 for the combined sequential percutaneous and intradermal allergy testing as described.

Coding Specifications

Modifier	Description	When to Use
`25`	Significant, separately identifiable evaluation and management service by the same physician on the same day	Use when a distinct E/M visit is provided on the same date as `95017` and is clinically significant and documented.
`26`	Professional component	Use if billing only the physician interpretation/reading component separate from technical services.
`59`	Distinct procedural service	Use when an unrelated procedure is performed on the same day that is separate from skin testing.
`52`	Reduced services	Use when testing is partially reduced or not fully completed and documentation supports reduced service.
`53`	Discontinued procedure	Use if testing is started but discontinued due to patient reaction or other valid clinical reason.
`76`	Repeat procedure by same provider	Use if the same test is repeated later the same day by the same provider.
`77`	Repeat procedure by another provider	Use if repeat testing is performed by a different provider the same day.
`59`	Distinct procedural service	Use to indicate a distinct procedural service when bundling edits might apply.
`78`	Unplanned return to the operating/procedure room by the same physician following initial procedure for a related procedure during the postoperative period	Rare for outpatient allergy testing; may apply if an unplanned return to procedure area is needed for an adverse event.
`80`	Assistant-at-surgery	Not typically applicable; include only if a qualified assistant actively assists during a procedure requiring an assistant.

Taxonomy Code	Specialty	Notes
207RH0000X	Allergy & Immunology	Board-certified allergists commonly perform `95017` testing.
207K00000X	Otolaryngology	ENT specialists perform testing when evaluating sinonasal allergic disease.
207L00000X	Pediatrics	Pediatricians with allergy training perform skin testing in children.
207P00000X	Internal Medicine	Internists or primary care physicians with allergy expertise may perform testing.
207R00000X	Pulmonology	Pulmonologists may perform testing as part of asthma/allergy evaluation.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`J30.9`	Allergic rhinitis, unspecified	Common indication for skin testing to identify aeroallergen sensitivities guiding avoidance and immunotherapy.
`T78.2XXA`	Anaphylactic shock, unspecified, initial encounter	Relevant in the evaluation of suspected systemic allergic reactions; skin testing requires caution and prior reaction history is documented.
`L50.9`	Urticaria, unspecified	Recurrent urticaria often prompts evaluation with skin testing to identify potential IgE-mediated triggers.
`T63.4X5A`	Toxic effect of venom of bees, assault, initial encounter (example venom exposure)	Venom testing (included in `95017`) is performed when history suggests sting hypersensitivity.
`Z91.048`	Allergy to venom (was bitten or stung), personal history	Used to document history of venom allergy and to justify venom skin testing.

Related CPT Codes

CPT Code	Description	Relationship to This Procedure
`95004`	Percutaneous tests, sequential and incremental, immediate type allergy tests; first test	Used when percutaneous prick/scratch tests are billed individually for single tests or limited panels prior to or instead of comprehensive `95017` testing.
`95024`	Intradermal tests, sequential and incremental, immediate type allergy tests; initial antigen (specify number of tests)	Billed when intradermal testing is performed and reported separately; intradermal testing may follow or be combined within `95017` sessions depending on documentation and payer rules.
`99213`	Office or other outpatient visit for the evaluation and management of an established patient, typically 15 minutes	Commonly billed on the same day when a separate, documented E/M service is provided before testing; may require modifier `25` when billed with `95017`.
`95165`	Professional services for allergen immunotherapy not including provision of allergenic extracts; single injection	Performed after identification of clinically relevant sensitivities via `95017` when immunotherapy is initiated; relates to follow-up therapeutic management.
`80305`	Drug screen, presumptive, any number of drug classes; any technique, non-automated	May be ordered in evaluation of suspected drug allergy prior to skin testing when clinically indicated; ancillary to allergy evaluation.
