Clinical & Coding Specifications
Clinical Context
A 58-year-old patient with end-stage renal disease (ESRD) is transitioning from in-center hemodialysis to an at-home hemodialysis program. The home therapy plan includes administrative oversight, professional pharmacy coordination, care coordination, and delivery/maintenance of all necessary dialysis supplies and equipment. Nursing services and dialysis drugs (e.g., heparin, erythropoietin) are billed separately.
The clinical workflow begins with a nephrology evaluation and training sessions to teach the patient and caregiver home hemodialysis procedures, vascular access care, machine operation, troubleshooting, and emergency protocols. The pharmacy team coordinates medication reconciliation, sterile supplies, and delivery schedules. A designated case manager schedules supplies, arranges service visits for equipment maintenance, and documents per diem administrative services. Ongoing clinical monitoring includes routine labs, telehealth check-ins, and periodic in-home nursing assessments; any nursing care or medications are billed in addition to the per diem administrative/service code S9335.
