Summary & Overview
HCPCS J2560: Phenobarbital Sodium Injection, up to 120 mg
HCPCS Level II code J2560 denotes an injectable dose of phenobarbital sodium, up to 120 mg, used for seizure control, sedation, and select acute indications. As a nationally recognized supply code for parenteral phenobarbital, J2560 drives billing for medication administration across outpatient clinics, hospital outpatient departments, emergency departments, and ambulatory infusion settings. Accurate coding affects provider claims, payer adjudication, and drug utilization reporting.
Key payers covered 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 phenobarbital injection, the typical sites of service where J2560 is billed, common billing modifiers (provided separately), and standard documentation elements needed to support medical necessity. The publication outlines benchmark topics such as usual billing practices, typical claim scenarios, and considerations for correct code use in medication administration lines.
This summary provides national-level context rather than state-specific guidance. Data not available in the input is noted where applicable. The reader will gain clarity on what J2560 represents, which clinical settings commonly use it, and which major payers are relevant to coverage and claims processing.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult or pediatric patient presenting to an emergency department, inpatient unit, or ambulatory infusion center with symptomatic seizures, status epilepticus, or severe central nervous system irritability requiring acute anticonvulsant therapy. A physician or advanced practice provider orders an intramuscular or intravenous injection of phenobarbital sodium when benzodiazepines are insufficient, contraindicated, or as part of a loading regimen for seizure control. Pharmacy staff prepare the correct concentration and dose (up to 120 mg per billing unit J2560), nursing administers the injection via IV push or IM route, and monitoring for respiratory depression, hypotension, and sedation occurs during and after administration. Documentation includes indication, dose and route, time of administration, patient response, and any airway or hemodynamic interventions. Typical sites of service include the emergency department, inpatient acute care unit, observation, and ambulatory infusion center.
Coding Specifications
| Modifier | Description | When to Use |

00 | Default/No modifier | Use when no specific modifier applies to the service. |
22 | Increased procedural services | Use if unusually extensive clinical work is documented related to the injection encounter (e.g., prolonged airway management for sedation from phenobarbital).
