Summary & Overview
HCPCS E1637: Hemostats, Single Unit
HCPCS Level II code E1637 denotes a single hemostatic product (“hemostats, each”) used to control bleeding in surgical and procedural settings. Nationally, this code is important because it captures billing for disposable hemostatic supplies that are commonly used across hospitals, ambulatory surgery centers, and procedural clinics. Tracking use and reimbursement of E1637 informs supply-cost management and procedural billing accuracy.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what E1637 represents, typical sites of service where it is used, and the implications for billing workflows. The publication outlines common modifiers associated with supply and surgical billing, notes where data was unavailable in the input, and identifies the clinical context in which hemostatic supplies are billed.
This piece provides national-level context useful for revenue cycle teams, surgical supply managers, and policy analysts who need clear definitions and coding context. It does not provide state-specific guidance and avoids prescriptive recommendations for clinical practice or billing decisions.
Billing Code Overview
HCPCS Level II code E1637 describes hemostats, each. This item represents a single-use hemostatic product intended to assist with bleeding control during surgical or procedural care. The service type is supply of a hemostatic agent for intraoperative or procedural use. The typical site of service is operating rooms, procedural suites, ambulatory surgery centers, and other inpatient or outpatient settings where surgical hemostasis is required.
Data not available in the input.
Clinical & Coding Specifications
Clinical Context
A typical patient is a 56-year-old male undergoing minor surgical procedures in an ambulatory surgical center or hospital operating room where topical or local hemostatic agents are required to control capillary or oozing bleeding. The clinician (general surgeon, otolaryngologist, oral/maxillofacial surgeon, or dermatologist) opens a sterile single-use topical hemostat E1637 during procedures such as skin excisions, mucosal resections, tonsillectomy adjunctive control, dental extractions with persistent bleeding, or wound debridement. The workflow: the patient is prepared and draped, the procedure is performed under local, regional, or general anesthesia, and when diffuse low-pressure bleeding or small vessel oozing is encountered that cannot be controlled efficiently with sutures, electrocautery, or pressure alone, the sterile topical hemostat E1637 is applied directly to the bleeding surface. The product is used per manufacturer instructions and may remain in the surgical site or be removed per clinical judgment. Documentation includes the device code E1637, quantity used, specific application site, reason for use (e.g., persistent oozing despite standard measures), and any applicable modifier (for example 62 for co-surgeon participation when applicable). Typical sites of service are ambulatory surgical centers, hospital outpatient departments, inpatient operating rooms, and dental offices providing surgical extractions. Common patient scenarios include anticoagulated patients with increased oozing, friable mucosa in oncology resections, and procedures in anatomically difficult-to-access areas where conventional hemostasis is inadequate.
