CPT code 99512 represents a clinician visit to a patient’s home to provide hemodialysis, a critical home-based renal replacement therapy for patients with kidney failure. As home dialysis programs expand, this service code captures the clinical activity of delivering dialysis care outside institutional settings and is relevant for payers, providers, and care managers considering access, quality, and care coordination implications nationally. Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for home hemodialysis visits, how payers approach coverage and claims processing for the service, common modifiers in billing, and where to look for related coding and reimbursement guidance. The publication also summarizes typical care settings and operational considerations for delivering hemodialysis in the home, and highlights benchmark topics and policy developments that influence adoption of home dialysis models.
