Summary & Overview
HCPCS A4725: Dialysate Solution 5000–5999 cc for Peritoneal Dialysis
HCPCS Level II code A4725 denotes a dialysate solution for peritoneal dialysis in a fluid volume greater than 4,999 cc and up to 5,999 cc, containing any concentration of dextrose. This supply code matters nationally because peritoneal dialysis is a widely used modality for chronic kidney disease management, and accurate coding for dialysis supplies affects clinical logistics, coverage determinations, and billing consistency across payers. Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will learn the clinical context of the supply described by A4725, typical sites where the product is used, and which major payers commonly cover such supplies. The publication provides benchmarks and coding context relevant to supply-level billing for peritoneal dialysis solutions, highlights common payer coverage patterns, and outlines where to find policy updates affecting supply reimbursement and medical necessity for peritoneal dialysis materials. Data not available in the input will be noted where applicable.
Billing Code Overview
HCPCS Level II code A4725 describes a dialysate solution for peritoneal dialysis: any concentration of dextrose in a single fluid volume greater than 4999 cc but less than or equal to 5999 cc.

Clinical & Coding Specifications
Clinical Context
A 58-year-old patient with end-stage renal disease managed with chronic peritoneal dialysis presents for routine exchange of dialysate. The care team prepares and delivers a single large-volume dialysate bag of dextrose-containing solution with a fluid volume measurement greater than 4999 cc but less than or equal to 5999 cc (A4725). The procedure occurs in an outpatient dialysis center or at the patient’s home under home infusion/peritoneal dialysis training and support. Workflow steps include verification of the prescription and concentrations, sterile bag preparation, connection to the patient’s peritoneal dialysis catheter using aseptic technique, instillation of the prescribed dialysate volume, monitoring for adequate dwell and patient tolerance, documentation of solution lot and volume, and disposal of supplies per infection-control protocols. Nursing documents the fill volume, dwell time, patient response, and any complications such as peritonitis signs or leakage. Billing is submitted using A4725 for the single large-volume dialysate solution; applicable modifiers may be appended to reflect special circumstances (for example, medically necessary unusual services or institutional/facility status). Typical sites of service are an outpatient dialysis facility, home health setting during peritoneal dialysis training or delivery, or an infusion/durable medical equipment distribution setting depending on payer rules.
