CPT code 90959 denotes monthly management of adolescents (ages 12–19) with end stage renal disease (ESRD), where the provider oversees all services related to the patient’s monthly care and conducts at least one face-to-face visit each month. This code reflects a longitudinal care management service specific to the pediatric-to-adolescent ESRD population and is relevant to clinicians, billing professionals, and payers because it encompasses coordination of complex renal care, treatment planning, and monitoring.

Key payers included in national discussions are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical intent and service setting, interpretation guidance for billing teams, and a summary of common modifiers used with this service. The publication also highlights benchmarking considerations, typical sites of service, and how CPT code 90959 fits within ESRD care pathways. Where payer-specific policy or coverage details exist, those are summarized to aid revenue cycle and compliance teams in aligning documentation and billing workflows with payer expectations.

This national-level summary is intended for health system administrators, coders, and clinicians who manage pediatric and adolescent ESRD populations and need clear reference material about this monthly management CPT code.
