Nephrology billing is uniquely difficult because dialysis billing operates on a monthly capitated payment model (ESRD Monthly Capitation Payment) that is entirely separate from standard fee-for-service, while non-dialysis nephrology visits involve complex CKD staging documentation requirements and high prior authorization burdens for erythropoiesis-stimulating agents and IV iron. A single miscoded CKD stage or missing MCP election can result in significant underpayment or denial across an entire patient panel.
Nephrology medical billing demands proficiency in ESRD Monthly Capitation Payment billing (90960–90962), CKD staging documentation, prior authorization tracking for ESAs and IV iron, and dialysis coding: hemodialysis (90935/90937), peritoneal dialysis (90945/90947), and office visits (99213–99215). Errors in coding or a missed MCP election can result in underpayment across an entire patient panel, and can prompt coding audits. Drawing on our track record in nephrology billing, we offer coding education, timely billing updates, and experience recovering previously denied claims.
Billed Right has provided nephrology billing support since 2006, serving practices across the US from our base in Longwood, Florida.
Common Pain Areas
- ESRD MCP billing errors can misstate an entire month's dialysis reimbursement in one mistake.

- Prior authorization for ESAs and IV iron can stall treatment and delay reimbursement.
- Home dialysis billing complexity adds training and support codes on top of the standard MCP.
- Medicare Secondary Payer coordination during the 30-month period can result in claims billed to the wrong primary payer.

Top Denial Reasons
Incorrect ESRD MCP Billing
Billing the wrong MCP code for the visit count, or billing separate E/M codes for services already bundled into the monthly payment, is a fast way to misstate a month's reimbursement.
CKD Stage Not Documented
Billed services have to be supported by documented CKD stage and lab values, and undocumented staging is an easy medical necessity denial.
Missing Prior Authorization for ESAs or IV Iron
Aranesp, Epogen, and IV iron products almost always require authorization tied to current hemoglobin and iron indices before they're reimbursed.
Medicare Secondary Payer Coordination Error
Billing Medicare as primary during the 30-month coordination period, or missing when it becomes primary after, both trigger MSP denials and recoupments.
Home Dialysis Training Visit Not Billed Correctly
Home dialysis training sessions have their own codes and documentation separate from the standard MCP, and billing them incorrectly is an avoidable denial.
Payer-Specific Considerations
Medicare is the dominant payer in nephrology because of the ESRD entitlement. Patients qualify for Medicare regardless of age after 3 months of dialysis, which puts most dialysis and CKD management claims under Medicare's rules rather than a patient's underlying commercial or Medicaid coverage. When a patient has both group health coverage and Medicare based on ESRD, the commercial plan stays the primary payer for a 30-month coordination period before Medicare takes over as primary, and billing the wrong payer as primary during that window is a common, avoidable denial. Commercial payers apply strict prior authorization requirements for ESAs like Aranesp (J0881/J0882) and Epogen (J0885/J0886) and IV iron products (Q0136), tying approval to documented hemoglobin and iron indices rather than approving on diagnosis alone.

Frequently Asked Questions
The ESRD MCP is a monthly bundled payment (codes 90960-90962, based on the number of face-to-face visits) that covers routine dialysis management instead of billing each visit separately. Missing the visit-count requirement or billing standard E/M codes on top of the MCP for the same services is one of the most common nephrology billing mistakes.
Chronic kidney disease stage (1 through 5) has to be documented with supporting lab values, primarily eGFR, to justify the level of management billed. An office visit coded for advanced CKD management without staging documentation to support it is an easy medical necessity denial.
Yes, in most commercial plans and increasingly in Medicare Advantage. Drugs like Aranesp (J0881) and Epogen (J0885/J0886), and IV iron products like Q0136, typically need authorization tied to documented hemoglobin and iron indices before they'll be reimbursed.
When a patient qualifies for Medicare based on ESRD but still has group health coverage, that commercial plan stays the primary payer for the first 30 months. Billing Medicare as primary during that window, or missing the point where Medicare becomes primary after it ends, both trigger MSP-related denials and recoupments.
Home hemodialysis and peritoneal dialysis (90935/90937 and 90945/90947 respectively) still roll into the monthly MCP, but training sessions, equipment, and support services have their own codes and documentation requirements that in-center dialysis doesn't need.
Standard fee-for-service pays per visit or procedure. Dialysis billing under the ESRD MCP pays one monthly rate per patient regardless of visit count above the required minimum, which means the billing focus shifts from coding every encounter to making sure the monthly election, visit counts, and case mix adjustments are correct.
