Summary & Overview
HCPCS A4707: Bicarbonate Concentrate Powder for Hemodialysis
HCPCS Level II code A4707 identifies a powdered bicarbonate concentrate packet used to prepare dialysate for hemodialysis. As a consumable dialysis supply, this code matters nationally because it is part of standard hemodialysis delivery and factors into supply billing, inventory management, and facility-level cost accounting across outpatient dialysis centers and hospital dialysis units. Payment and coverage for dialysis supplies affect operational margins for dialysis providers and can influence patient access to consistent treatment.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn how A4707 is used to bill for bicarbonate concentrate supplies, the typical clinical context and sites of service where the product is used, and which payers commonly reimburse for dialysis consumables. The publication also provides benchmarking guidance, common modifier usage patterns (listed separately), and notes on documentation practices relevant to supply billing. Data not available in the input is clearly identified where applicable.
Billing Code Overview
HCPCS Level II code A4707 describes bicarbonate concentrate, powder, for hemodialysis, per packet. This item represents a dialysate component supplied in powdered bicarbonate form intended for use during hemodialysis treatments. The service type is dialysis supply / dialysis solution component. The typical site of service is outpatient dialysis clinics and hospital-based hemodialysis units, where concentrates are reconstituted and used in dialysis machines for patient treatments.
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with end-stage renal disease (ESRD) receiving maintenance in-center hemodialysis. During each dialysis session a trained dialysis nurse or technician prepares dialysate using concentrate components including A4707 bicarbonate concentrate, powder, per packet. The workflow: prior to treatment the dialysis nurse confirms the patient’s prescription (bicarbonate concentration in dialysate), inspects and opens the A4707 packet, mixes the powder with sterile water according to manufacturer instructions into the dialysis machine’s concentrate chamber or a proportioning system, performs concentration and conductivity checks, documents lot number and packet use in the dialysis record, and proceeds with machine setup and patient connection. Typical site of service is an outpatient dialysis facility (end-stage renal disease clinic) or hospital dialysis unit. Clinical indications are correction and maintenance of acid-base balance during hemodialysis for diagnoses such as chronic kidney disease, acute kidney injury requiring dialysis, or toxin removal when hemodialysis is indicated. Patients are monitored for hemodynamic stability, electrolyte shifts, and signs of inadequate dialysate mixing during and after treatment.
