Summary & Overview

CPT 95027: Percutaneous Airborne Allergen Skin Prick Testing with Interpretation

CPT code 95027 represents percutaneous (skin prick) testing using sequential and incremental airborne allergenic extracts to identify immediate hypersensitivity reactions. The procedure includes interpretation and a report that specifies the number of tests performed. This code is widely used in outpatient allergy and immunology settings and matters nationally because accurate coding ensures appropriate clinical documentation, claims processing, and consistent capture of allergy diagnostic encounters across payer systems.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for skin prick testing, typical sites of service, and the elements captured by the code. The publication also summarizes common modifiers associated with allergy testing claims and highlights areas where policy guidance or documentation practices commonly affect reimbursement and claim adjudication.

This analysis provides practical, policy-focused content: a clear explanation of the code’s clinical meaning, documentation elements reflected by the code, and what to expect in payer policies at a national level. Data not available in the input is noted where applicable; the focus remains on establishing a concise reference for clinicians, coders, and policy analysts working with allergy diagnostic services billed under CPT code 95027.

Billing Code Overview

CPT code 95027 describes a provider-performed skin prick testing procedure in which sequential and incremental airborne allergenic extracts are introduced into the skin to determine immediate allergic response. The clinician interprets the results and documents findings in a report that specifies the number of tests performed.

Service type: Diagnostic allergy testing using percutaneous (skin prick) technique
Typical site of service: Outpatient clinic or office-based allergy/immunology practice; may also be performed in hospital outpatient departments

Clinical & Coding Specifications

Clinical Context

A 28-year-old patient presents to an outpatient allergy clinic with a six-month history of seasonal nasal congestion, sneezing, itchy eyes, and intermittent wheeze that worsen during spring. The allergist performs 95027 (sequential incremental intradermal testing with interpretation and report) after initial history and review of prior skin prick testing are inconclusive or when greater sensitivity is required to evaluate airborne allergen sensitization. The clinical workflow: the patient is pre-screened for contraindications (severe dermatographism, recent antihistamine use, unstable asthma, beta-blocker therapy), informed consent is obtained, and baseline vitals are recorded. A series of diluted airborne allergenic extracts (e.g., pollens, molds, dust mites, animal dander) are injected intradermally in sequential concentrations while monitoring for immediate wheal-and-flare responses. The provider documents the number of tests, measures wheal sizes, interprets positivity criteria, and generates a written report that includes test results and clinical interpretation. Post-test observation is provided to monitor for systemic reactions, and results are used to guide environmental control measures, pharmacotherapy, or consideration of allergen immunotherapy.

Coding Specifications

Modifier	Description	When to Use
`26`	Professional component	Use when billing only the physician’s interpretation and report separate from the technical skin-test administration performed by facility staff.
`59`	Distinct procedural service	Use when another unrelated procedure or service was performed on the same date and it is not normally reported together with `95027`.
`76`	Repeat procedure by same physician	Use when the intradermal testing is repeated by the same provider on the same day.
`77`	Repeat procedure by another physician	Use when another physician repeats the testing on the same day.
`52`	Reduced services	Use when testing is partially reduced or fewer allergens are tested than typical.
`53`	Discontinued procedure	Use if testing is started but discontinued due to patient reaction or other acute issue.
`78`	Unplanned return to the operating/procedure room	Applicable if the patient requires an unexpected return for management of a systemic reaction during the same encounter.
`80`	Assistant at surgery	Use when a qualified assistant participates in the procedure and payer allows assistant modifiers for this service.
`QX`	Ordering/Referring modifier (CLIA waived)	Use when applicable lab-related ordering/referral rules apply; include when required by payer for services associated with lab testing.
`TC`	Technical component	Use when billing only the technical component (site, supplies, nursing/technician administration) and not the physician interpretation.
`GA`	Waiver of liability statement on file (voluntary)	Use when the provider has a signed waiver for Medicare-covered services.
`QK`	Medical direction of two or more assistants	Use when the provider medically directs multiple assistants involved in the procedure, if applicable per payer policy.
`QY`	Attending physician absence; physician not available to supervise	Use in rare circumstances defined by payer rules when physician supervision is absent but services are furnished by qualified personnel.
`59`	Distinct procedural service (alternate placement)	Use to indicate a distinct service when multiple diagnostic procedures are furnished on the same day.

Taxonomy Code	Specialty	Notes
207K00000X	Allergy & Immunology	Board-certified allergists/immunologists commonly perform and interpret intradermal testing.
2084P0800X	Pediatrics (Allergy focus)	Pediatric allergists perform intradermal testing in children when indicated.
207RA0000X	Otolaryngology	ENTs may perform allergy testing as part of sinonasal evaluation.
207L00000X	Pulmonology	Pulmonologists involved in asthma care may perform or interpret allergy testing.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`J30.1`	Allergic rhinitis due to pollen	Common indication for airborne allergen intradermal testing to identify pollen sensitization.
`J30.2`	Other seasonal allergic rhinitis	Used when seasonal patterns suggest non-pollen airborne allergens; testing identifies relevant triggers.
`J30.8`	Other allergic rhinitis	Applied for allergic rhinitis not otherwise specified; intradermal testing helps specify allergens.
`J30.9`	Allergic rhinitis, unspecified	Used when symptoms are consistent with allergic rhinitis and testing is needed for diagnosis.
`J45.40`	Moderate persistent asthma, unspecified	Allergy testing aids in identifying triggers contributing to asthma control decisions.
`R06.2`	Wheezing	Symptom code that often accompanies allergic airway disease and may prompt allergy testing.
`L50.0`	Allergic urticaria	Skin manifestations that can be related to airborne allergen sensitization; testing may be part of evaluation.

`95004`	Percutaneous allergy skin tests, immediate type reaction, sequential and incremental, with reintroductions, single or multiple antigens, intradermal, including test interpretation and report	Performed when testing for insect venoms or other allergens; `95004` is an intradermal test code used for certain panels and may be used in combination depending on allergen type and payer rules.
`95024`	Intradermal tests, initial 1 or 2 tests	Often used for initial basic intradermal testing; may precede larger panels billed under `95027` if protocols vary.
`95044`	Patch or epicutaneous tests, application and reading of patch tests	Performed when contact dermatitis evaluation is needed in addition to airborne allergen testing.
`95115`	Professional services for allergen immunotherapy not including provision of antigens; single injection	Used when test results lead to initiation of allergen immunotherapy injections; documents professional administration separate from antigen provision.
`95070`	Skin test, intradermal, tuberculosis antigen, quantitative (e.g., PPD), requires separate workflow	Different indication (tuberculosis screening) but similar skin testing technique; relevant when multiple skin tests are performed for comprehensive evaluation.
