What are the main CPT codes for ESRD billing?

The primary ESRD monthly codes are 90960-90966. Outpatient codes 90960-90962 correspond to 4+, 2-3, and 1 face-to-face visits. Codes 90963-90966 cover home dialysis. Hemodialysis (90935, 90937) and peritoneal dialysis (90945, 90947) cover individual sessions outside the MCP bundle.

How does monthly capitation payment work in nephrology?

Medicare pays a single monthly rate per ESRD patient. The CPT code and payment rate is determined by face-to-face visits: 4+ (90960), 2-3 (90961), 1 (90962). Each visit requires documented clinical content to count.

Why are ESRD claims commonly denied?

ESRD claim denials most commonly occur due to insufficient visit documentation, incorrect MCP tier billing, bundling errors, and incorrect modifier or place of service codes — particularly on telehealth claims.

Can nephrology services be billed with E/M codes alongside MCP codes?

In some circumstances, yes — but the requirements are strict. A separate E/M code can be billed alongside an MCP code when the E/M visit is for a condition that is completely unrelated to the patient's ESRD and is clearly documented as a separate problem.

What documentation is required for MCP billing?

Each qualifying MCP visit must be documented with a dated, signed note that reflects: a face-to-face encounter between the physician and the patient, clinical assessment of the patient's current dialysis status, review of relevant parameters, and the physician's clinical reasoning.

How can nephrology practices reduce denial rates?

The most effective denial reduction strategies in nephrology combine systematic visit tracking, documentation quality improvement with physician-specific feedback, regular coding audits focused on ESRD bundling compliance, denial pattern analysis by code and payer, and pre-submission claim scrubbing with nephrology-specific rules.
