Nephrology Billing Services
Nephrology billing services covering ESRD dialysis, chronic kidney disease management, nephrology E/M.
What Nephrology Billing Has to Handle
Nephrology billing spans two different payment models at once: chronic kidney disease management billed as standard encounters, and end-stage renal disease physician services paid monthly against documented visit counts. Patients moving between them change how the month is billed.
- ESRD patients classified by dialysis setting and visit count each month
- CKD management billed as standard encounters with supporting documentation
- Transitions from pre-ESRD care into dialysis handled under the correct model
- Kidney biopsy and procedure billing captured alongside management services
Nephrology Billing Services Explained
Nephrology billing centers on the unique ESRD payment model, dialysis procedure coding, and chronic kidney disease management E/M coding services. CMS Medicare covers the majority of ESRD patients under the bundled ESRD payment system, which bundles dialysis treatments, certain drugs, and laboratory services into monthly capitation payments billed through dialysis facilities.
Medsure RCS manages nephrology revenue cycle management including ESRD monthly capitation codes for physician services, outpatient and inpatient nephrology E/M encounters, kidney biopsy billing, and the complex payment rules that apply when a patient transitions from pre-ESRD CKD management to dialysis initiation. Nephrology is part of our specialty medical billing program, with a focus on Medicare billing compliance for ESRD and medical billing for CKD management. Centres billing monthly ESRD physician services are covered in more depth under dialysis and ESRD billing. Monthly ESRD services are coded by visit count, with four or more visits at 90960.
How It Works: Step by Step
Patient ESRD Status Classification
Each dialysis patient is classified correctly as home dialysis, in-facility dialysis, or pre-ESRD CKD to apply the correct monthly capitation code and visit count requirements.
Monthly Capitation Code Selection
ESRD monthly capitation codes (90951-90970) are selected based on patient age, dialysis setting, and whether the full month of care was provided by the billing physician.
Inpatient and Outpatient E/M Billing
Non-ESRD nephrology encounters are billed using standard E/M codes with documentation supporting the complexity and decision-making required for CKD and related conditions.
Transitions of Care Management
Dialysis initiation, changes in dialysis modality, and transplant transitions require specific code selection and documentation to bill the period correctly.
Why This Matters for Your Revenue Cycle
Every ESRD monthly capitation claim uses the correct code based on age, setting, and full vs partial month care.
Nephrology-specific code review prevents the most common CKD and ESRD billing errors.
Nephrology claims are submitted and followed up within structured timely filing windows.
All ESRD monthly capitation codes from 90951 through 90970 are applied based on patient-specific criteria.
Common Mistakes in Nephrology Billing Services
Wrong ESRD Capitation Code for Patient Age
ESRD monthly capitation codes are age-specific. Codes for patients under 2, 2-11, 12-19, and 20 and over are different. Selecting the wrong code based on incorrect age documentation results in incorrect reimbursement.
Full Month Code When Month Was Partial
When a physician provides ESRD care for only part of a month (due to hospitalization, transfer, or death), the partial month code is required, not the full month code. Billing the full month code for a partial month creates an overpayment situation.
Separate Billing of Bundled Dialysis Services
Under the ESRD bundled payment system, certain drugs, laboratory tests, and services are bundled into the facility payment. Separately billing these bundled services on the professional claim is a compliance issue.
Missing Visit Count Documentation
ESRD monthly capitation codes require a minimum number of patient visits per month. If the visit count is not documented, the capitation claim lacks support for the services billed.

Nephrology Billing Services, Frequently Asked Questions
The ESRD monthly capitation pays physicians a fixed monthly amount for managing a dialysis patient's ESRD care. It is billed using codes 90951-90970 based on patient age, dialysis setting (facility vs home), and whether the physician provided a full or partial month of care.
E/M services related to the ESRD condition are bundled into the monthly capitation payment and cannot be billed separately. However, E/M services for unrelated medical problems on a dialysis day can be billed with modifier 25 when clearly documented as separately identifiable.
The month a patient initiates dialysis, the ESRD monthly capitation code is used from the initiation date through end of month. For the pre-ESRD CKD management prior to that date, standard E/M codes apply. The initiation date must be clearly documented to bill the partial month correctly.
Yes. Home dialysis training (90989-90993) is separately billable for the physician's evaluation and training activities when a patient transitions to home dialysis. These are not bundled into the monthly capitation code.
