Summary & Overview
HCPCS J2004: Lidocaine HCl with Epinephrine Injection, 1 mg
HCPCS Level II code J2004 denotes the injectable combination of lidocaine hydrochloride with epinephrine (1 mg) used for localized anesthesia with vasoconstriction. Nationally, this code is relevant across outpatient procedural care, ambulatory surgery, and office-based minor procedures where hemostasis and local anesthesia are needed. It captures administration of a specific drug formulation rather than the procedure itself, which affects billing, reimbursement, and inventory management.
Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for use of J2004, the typical sites of service, and the implications for medical billing teams and revenue cycle workflows. The content outlines common payer coverage considerations and highlights what to expect in claim adjudication for drug administration services.
This publication also presents benchmarks and coding practice notes where available, identifies gaps in publicly available policy language, and summarizes how J2004 interacts with procedure coding in ambulatory and office settings. Data not available in the input is noted where applicable.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult presenting to an outpatient surgical clinic, emergency department, or dermatology office requiring local anesthesia for a minor surgical procedure or laceration repair. The clinician prepares and administers J2004 (injection, lidocaine HCl with epinephrine, 1 mg) to provide local anesthesia and vasoconstriction at the procedure site. Workflow: patient assessment and consent → review of allergies and cardiac history (epinephrine precautions) → selection of appropriate local anesthetic and concentration → skin antisepsis → infiltration of the anesthetic with atraumatic technique → performance of the procedure (e.g., wound repair, excision, incision and drainage) → post-procedure monitoring for hemostasis and adverse effects (tachycardia, hypertension, local tissue ischemia). Typical sites of service include outpatient surgical centers, physician offices (surgery, dermatology, emergency medicine), and hospital outpatient departments. Typical modifiers that may be appended include those indicating unusual service circumstances, laterality, or professional vs. technical components as clinically applicable.
