Summary & Overview
HCPCS J7354: Cantharidin 0.7% Topical Single-Unit Applicator
HCPCS Level II code J7354 designates a single-unit topical applicator of cantharidin 0.7% (3.2 mg) used for cutaneous treatment. The code captures the medicated product rather than the professional application procedure, and it is relevant for billing in outpatient dermatology and office-based procedure settings. Nationally, accurate reporting of this HCPCS code matters for appropriate product reimbursement, tracking utilization of topical vesicants, and ensuring consistency in claims for skin lesion treatments.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The content outlines payer coverage patterns where available and identifies benchmarks for coding and claim submission practices. Readers will learn the clinical context for use of cantharidin 0.7% in single-dose applicators, typical sites of service, and which aspects of billing are tied to the product versus professional services. The publication also summarizes common modifiers used with HCPCS product codes and notes where input data is not available for associated taxonomies, ICD-10 diagnoses, or related codes. Data not available in the input is explicitly indicated where applicable.
Billing Code Overview
HCPCS Level II code J7354 represents cantharidin for topical administration, 0.7%, single unit dose applicator (3.2 mg). This code is used to report the supply of a topical vesicant agent formulated at 0.7% concentration in a single-unit applicator intended for cutaneous application.
Service Type: Topical dermatologic medication administration (single-unit applicator)

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult or pediatric outpatient presenting to a dermatology clinic or primary care office with one or a few small, well-demarcated cutaneous lesions suspicious for molluscum contagiosum, common warts (verruca vulgaris), or other localized superficial epidermal lesions amenable to topical blistering therapy. After clinical evaluation and consent, the provider isolates the lesion, applies a single-use J7354 cantharidin 0.7% unit-dose applicator directly to the lesion, avoids surrounding normal skin, and allows blistering to occur. The patient or caregiver receives post-application instructions for wound care and return precautions. Typical workflow steps: history and focused skin exam, photographic documentation as needed, selection and preparation of lesion(s), application of J7354 cantharidin applicator, brief observation for immediate adverse reaction, and scheduling follow-up or additional treatments as indicated.
