Summary & Overview
HCPCS Level II A4720: Dialysate Solution for Peritoneal Dialysis (>249–999 cc)
HCPCS Level II code A4720 identifies packaged dialysate solution used in peritoneal dialysis when the fluid volume is greater than 249 cc and up to 999 cc. This supply code is central to billing for ambulatory and home-based peritoneal dialysis programs, where timely access to appropriately sized dialysate bags affects clinical workflows, patient self-care, and supply chain management nationally. The code matters because it delineates the billed supply unit that payers use to adjudicate claims for outpatient and home dialysis services, impacting coverage determinations, reimbursement rates, and patient cost-sharing.
Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The report provides a national perspective on coverage patterns and administrative considerations across these major commercial and federal payers.
Readers will learn the clinical and billing context for A4720, expected sites of service, and common operational considerations when supplying dialysate solution in the specified volume range. The publication summarizes available benchmarks where present, highlights recent policy or coding clarifications when applicable, and outlines typical payer rules and billing workflows relevant to peritoneal dialysis supplies. Data not available in the input will be noted where applicable.

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with end-stage renal disease maintained on peritoneal dialysis presents to an outpatient dialysis clinic for routine ambulatory supply delivery and exchange training. The clinician orders dialysate solution in single-use bags sized between 250–999 cc for use during automated peritoneal dialysis (APD) cycler fills or manual daytime exchanges. Typical workflow: nursing confirms prescription and bag concentration (dextrose percentage) based on ultrafiltration goals, documents patient weight and recent peritoneal equilibration test results, prepares aseptic supplies, performs peritoneal catheter connection and priming, instills prescribed dialysate volume, observes dwell time and outflow, documents volume instilled and drained, and disposes of used solution per infection-control protocols. The site of service is most commonly an outpatient dialysis center or the patient’s home during home peritoneal dialysis care; occasional use occurs in hospital inpatient wards when short-volume exchanges are required for clinical management or testing.
