Nephrology Billing Services
Nephrology billing centers around the unique monthly capitation payment model for dialysis patients, ESRD Monthly Capitation Payment coding, and chronic kidney disease stage-based management. The transition from CKD to dialysis to transplant creates billing workflow changes at each stage. Our nephrology billing team ensures proper reimbursement across the full spectrum of kidney care.

Common Billing Friction in Nephrology
ESRD Monthly Capitation Payment Coding
Dialysis patients are billed using Monthly Capitation Payment codes (90960-90970) based on the number of face-to-face visits per month. The MCP rate varies by age group and visit frequency, with specific documentation requirements for each visit.
Dialysis Modality and Access Procedure Billing
Billing differs for hemodialysis versus peritoneal dialysis patients, and vascular access procedures (fistula creation, catheter placement, access revision) have distinct codes with technical and professional component splits.
CKD Stage Transition Documentation
As patients progress through CKD stages, the diagnosis coding, covered services, and billing models change. Proper staging documentation and timely transition from stage-based E/M billing to ESRD MCP billing is critical for revenue continuity.
Nephrology-Specific Payer Issues We Watch For
Medicare
Issue: Monthly capitation payment (MCP) codes (90960-90962) are selected based on the number of face-to-face visits per month — documentation must support each visit with separate dated encounter notes
Our approach: We verify face-to-face visit counts against MCP code selection for every monthly claim and downcode when documentation does not support the billed visit count
UnitedHealthcare
Issue: Does not recognize the ESRD MCP codes for non-Medicare patients and requires per-visit billing instead of monthly capitation
Our approach: We maintain a UHC-specific nephrology billing workflow that converts monthly capitation claims to per-visit E/M billing for commercial ESRD patients
BCBS
Issue: Requires separate prior authorization for erythropoiesis-stimulating agents (EPO/ESA) used in dialysis with specific hemoglobin threshold documentation
Our approach: We track hemoglobin levels for all dialysis patients and submit ESA prior authorizations with lab data supporting the payer-specific hemoglobin thresholds
Humana
Issue: Bundles AV fistula and graft access management codes with the monthly dialysis payment, denying separate claims for vascular access procedures performed in the dialysis unit
Our approach: We document vascular access procedures with distinct operative notes and bill separately when performed outside the routine dialysis session with appropriate modifiers

Billing for kidney function panels, dialysis adequacy testing, and renal imaging studies.
Key Nephrology CPT Codes
| CPT Code | Description | Avg. Reimbursement |
|---|---|---|
| 90960 | ESRD-related services, per month, for patients 20+ years, with 4+ face-to-face visits | $285 |
| 90961 | ESRD-related services, per month, with 2-3 face-to-face visits | $245 |
| 90962 | ESRD-related services, per month, with 1 face-to-face visit | $195 |
| 90935 | Hemodialysis procedure with single evaluation | $82 |
| 90937 | Hemodialysis procedure requiring repeated evaluation | $118 |
| 90945 | Non-hemodialysis dialysis procedure (peritoneal) | $95 |
| 50360 | Renal transplant, allotransplantation | $2,800 |
| 90951 | ESRD-related services for patients under 2 years, full month | $620 |
Real Results
The Challenge
A 6-provider nephrology group managing 380 dialysis patients was losing revenue on monthly capitation payment coding, missing transplant evaluation billing, and had inconsistent ESRD PPS composite rate billing across two dialysis units
Our Approach
We standardized MCP coding across all dialysis patients, implemented transplant evaluation and follow-up code capture, and reconciled ESRD PPS billing against CMS requirements for both dialysis units
Key Outcomes
- check_circle Monthly capitation revenue increased by $14 per patient per month
- check_circle Transplant evaluation billing added $7,800 per month
- check_circle ESRD PPS composite rate billing errors eliminated
- check_circle Annual revenue increased by $189K
“We were not billing transplant evaluation codes at all. MedPrecision identified that gap and it added nearly $100K annually to our practice.”
Why General Billing Teams Miss Nephrology Issues
General billing staff handle dozens of specialties and rarely develop the depth needed for nephrology coding nuances. Here is what gets missed.
Modifier and bundling errors
Specialty-specific modifier rules and CCI edits are frequently overlooked by teams that do not work exclusively in nephrology.
Under-coding high-complexity visits
Nephrology encounters often qualify for higher-level E/M codes, but generalist billers default to mid-level codes to avoid audit risk.
Missed payer-specific rules
Each payer has unique coverage and documentation requirements for nephrology procedures that general teams rarely memorize.
Slow denial turnaround
Without specialty knowledge, appeal letters lack the clinical specificity needed to overturn nephrology denials quickly.
“Nephrology practices with dialysis units leave the most revenue on the table with monthly capitation coding errors and missed transplant evaluation billing. The per-patient revenue impact is small, but across 300+ dialysis patients it adds up to six figures.”

Nephrology Billing Terms
- Monthly Capitation Payment (MCP)
- Medicare's per-month payment for ESRD-related physician services including all outpatient dialysis-related care. Payment level varies based on patient age and the number of face-to-face visits per month (90951-90970 code series).
- ESRD PPS (Prospective Payment System)
- Medicare's bundled payment system for dialysis facility services that includes a base rate adjusted for patient and facility characteristics. Covers dialysis treatment, drugs, lab tests, and supplies in a single composite payment.
- Composite Rate
- The bundled per-treatment payment covering routine dialysis services, supplies, equipment, and certain drugs and tests. Items not included in the composite rate can be billed separately with appropriate HCPCS codes.
- Vascular Access Management
- Procedures related to creating, maintaining, and managing arteriovenous fistulas, grafts, and catheters used for dialysis. Separately billable when performed outside the routine dialysis session with proper documentation.
- Transplant Evaluation Coding
- Codes for the evaluation and management of patients being assessed for kidney transplant eligibility, including pre-transplant workup, listing management, and post-transplant follow-up care.
- EPO/ESA Administration
- Erythropoiesis-stimulating agent administration for dialysis-related anemia. Billing requires documentation of hemoglobin levels, dosage adjustments, and prior authorization for commercial payers with specific lab value thresholds.

Request Review arrow_forwardHow does monthly capitation payment work for dialysis patients?
MCP codes (90960-90970) provide a monthly bundled payment for managing dialysis patients based on age and the number of face-to-face visits provided that month. Four or more visits per month yields the highest rate, while 2-3 visits or 1 visit yields progressively lower rates. We track visits and bill the correct MCP level each month.
How do you bill for vascular access procedures?
Vascular access procedures are billed with procedure-specific CPT codes depending on the type of access (AV fistula, AV graft, tunneled catheter) and whether it is initial creation, revision, or declotting. We apply correct professional and facility component modifiers based on the site of service.
What changes when a CKD patient starts dialysis?
When a patient initiates dialysis, billing transitions from standard E/M office visits to the ESRD Monthly Capitation Payment model. We manage this transition including the first month's partial billing, patient education session coding, and establishing the monthly visit tracking workflow.
