HCPCS J0131: Injection Acetaminophen, 10 mg

HCPCS Level II code J0131 denotes injectable acetaminophen measured in 10 mg units and is used to bill for parenteral administration of this analgesic/antipyretic agent. Nationwide, injectable acetaminophen is relevant for inpatient and procedural pain management protocols, perioperative care, and settings where oral administration is not feasible. The code matters because it standardizes reporting for an increasingly utilized non-opioid analgesic option that can affect medication utilization patterns, inpatient pharmacy spend, and perioperative pain pathways.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find benchmarks and coverage considerations for common payers, an overview of clinical contexts where injectable acetaminophen is billed, and notes on service lines and typical sites of service. The publication aims to clarify billing classification, operational contexts for use, and payer presence to help revenue integrity, coding teams, and policy analysts understand where J0131 fits within hospital and ambulatory procedural billing workflows.

Billing Code Overview

HCPCS Level II code J0131 represents the injection formulation of acetaminophen, described as “Injection, acetaminophen, not otherwise specified, 10 mg.” The service type is an injectable analgesic/antipyretic medication administration. The typical site of service for this code is acute care settings such as hospitals, ambulatory surgical centers, or other infusion-capable facilities where parenteral medications are administered.

Data not available in the input.

Clinical Context

A typical patient is an adult presenting to an outpatient infusion center or emergency department with acute severe pain or when oral acetaminophen is contraindicated or ineffective (for example, post-operative pain, acute musculoskeletal injury, or severe headache where oral intake is not feasible). The clinician (an emergency physician, anesthesiologist, hospitalist, or infusion nurse under physician order) verifies medication allergies, calculates dose based on indication and milligram strength, prepares the intravenous or intramuscular J0131 product, documents informed consent when required, and administers the injection. Vital signs and pain scores are monitored before and after administration. The encounter may include evaluation and management, procedural analgesia, or adjunctive therapies; medication administration is documented in the medication administration record, including lot number, route, dose, and time. Billing uses HCPCS Level II code J0131 for the supplied injected acetaminophen product (10 mg unit), with appropriate modifiers to indicate service circumstances and any related professional services.
