HCPCS J3245: Injection, tildrakizumab, 1 mg

HCPCS Level II code J3245 designates a unit of the monoclonal antibody tildrakizumab (1 mg) used for subcutaneous biologic therapy. As a drug-specific HCPCS Level II code, J3245 is used on outpatient professional and facility claims to report the medication supplied for dosing and billing of biologic treatments. Nationally, accurate reporting of this code matters for drug spend tracking, utilization monitoring, and payer coverage decisions for specialty injectable therapies.

Key payers included in this overview are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the code and its clinical use, typical sites of service where the product is administered, and what is commonly reported alongside such HCPCS drug codes. The publication also outlines the types of benchmarks and policy topics typically relevant to this code, including reimbursement reporting, prior authorization considerations, and billing units for injectable biologics. Data not available in the input is noted where applicable.

This summary provides clinicians, billing professionals, and policy analysts a national-level reference for identification and clinical context of HCPCS Level II code J3245, and orients readers to the sections covering billing practice, payer coverage patterns, and coding considerations related to tildrakizumab injections.

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult with moderate-to-severe plaque psoriasis being treated with subcutaneous biologic therapy. The patient presents to an outpatient dermatology infusion/medication administration clinic or specialty pharmacy clinic for a scheduled maintenance dose of tildrakizumab. The visit workflow includes medication verification and consent, screening for active infection or contraindications, vital signs and focused skin exam, verification of the prescribed dose and lot number, preparation of the J3245 drug (tildrakizumab, 1 mg) per manufacturer instructions, and subcutaneous injection by a licensed clinician (nurse, physician assistant, or physician). Documentation includes the specific HCPCS code J3245 with number of milligrams administered, the injection site, lot number, expiration date, route (subcutaneous), and any observed immediate adverse reaction. Time-based observation (typically 15–30 minutes) is documented when required by clinic policy or payor. Billing may be submitted by the administering facility or clinic under the appropriate place of service; payer adjudication depends on plan medical drug coverage policies and prior authorization status.
