Summary & Overview
HCPCS J2252: Midazolam Injection 1 mg, IV
HCPCS Level II code J2252 denotes an intravenous formulation of midazolam in 0.8% sodium chloride, billed per 1 mg and designated as not therapeutically equivalent to J2250. This drug-level code matters nationally because it supports billing specificity for sedative agents used in procedural sedation and anesthesia adjuncts across inpatient and outpatient settings. Precise coding affects claims processing, drug pricing transparency, and interoperability between pharmacy and facility billing.
Key payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of coverage considerations and billing benchmarks relevant to these major payers, an explanation of clinical contexts where J2252 is used, and guidance on how the code differs from related midazolam entries. The publication outlines common billing modifiers and service-line implications, notes typical sites of service such as hospitals and ambulatory surgery centers, and highlights areas where payer policy language commonly varies.
This summary equips billing managers, revenue cycle professionals, and clinical administrators with the contextual and operational information needed to recognize when J2252 applies, how it is reported on service lines, and what to expect from major payers at a national level. Data not available in the input is noted where applicable.

Typical Site of Service: Hospital inpatient or outpatient settings, ambulatory surgery centers, and procedural suites where IV sedatives are administered
Clinical & Coding Specifications
Clinical Context
A 62-year-old outpatient scheduled for brief procedural sedation prior to an endoscopic or minor interventional procedure receives intravenous midazolam formulated in 0.8% sodium chloride, billed with J2252 per milligram. The common clinical workflow: patient arrives to the endoscopy suite or ambulatory surgical center for conscious sedation; pre-procedure assessment documents ASA status, allergies, current medications, and airway risk; IV access is established; baseline vital signs and supplemental oxygen are applied; small incremental boluses of midazolam are administered intravenously by the proceduralist or anesthesia professional to achieve anxiolysis and amnesia; monitoring includes continuous pulse oximetry, telemetry, and periodic blood pressure checks; reversal agent flumazenil is available if oversedation occurs. Typical sites of service include hospital outpatient departments, ambulatory surgical centers, endoscopy suites, and emergency departments for short procedural sedation. Typical patient scenarios include sedation for upper endoscopy (EGD), colonoscopy with trainee assistance, minor bedside procedures (e.g., cardioversion, joint aspiration), or brief radiologic interventions requiring anxiolysis and amnesia.
