Summary & Overview
HCPCS J2253: Midazolam (Seizalam) Injection, 1 mg
HCPCS Level II code J2253 denotes a 1 mg injectable dose of midazolam (Seizalam), a short-acting benzodiazepine used for sedation, procedural anxiolysis, and acute seizure control. Nationally, this code matters because it tracks administration of a commonly used parenteral sedative in acute care and procedural settings and impacts billing for medication costs and per-dose reporting.
Payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for midazolam injections, typical sites of service where J2253 is billed, and the payer mix relevant to national reimbursement and coverage patterns. The publication outlines benchmark considerations, common billing modifiers associated with injectable medications (listed elsewhere in the full publication), and implementation notes relevant to facility and pharmacy billing workflows.
This summary delivers practical reference material for revenue cycle, clinical coding, and policy teams seeking a national perspective on how midazolam injections are represented in claims. Data not available in the input is noted where applicable in detailed sections of the full document.
Billing Code Overview
HCPCS Level II code J2253 describes an injection of midazolam (Seizalam), 1 mg. This billing code represents a single-dose injectable medication administration for the benzodiazepine midazolam, commonly used for sedation, procedural anxiolysis, and acute seizure management.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult or pediatric patient requiring procedural sedation or conscious sedation for a diagnostic or therapeutic procedure in an outpatient endoscopy suite, ambulatory surgery center, or emergency department. The treating clinician administers J2253 (midazolam, 1 mg) intravenously for anxiolysis, sedation, or as an adjunct to general anesthesia. A common scenario: a 45-year-old patient presenting for elective colonoscopy who receives titrated IV midazolam for conscious sedation, monitored by nursing and a proceduralist with continuous pulse oximetry, blood pressure, and cardiac monitoring; airway equipment and reversal agents (flumazenil) are immediately available. Typical workflow: pre-procedure assessment and informed consent, medication administration (recording dose and times), procedural monitoring, recovery in a post-anesthesia care area, and documentation of sedation level and discharge criteria. Typical sites of service include ambulatory surgery centers, hospital outpatient departments, gastroenterology endoscopy suites, and emergency departments.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
23 | Unusual anesthesia | Use when a procedure is normally done without general anesthesia but due to unusual circumstances general anesthesia is required and reported separately; applicable when IV midazolam contributes to deeper-than-expected sedation and separate anesthesia reporting is appropriate. |
