Nephrology's ESRD Monthly Capitation Payment pays a different rate depending on documented visit count — miss the fourth visit in your notes and you're billing at half rate without knowing it, on top of vascular access and transplant services that fall entirely outside the ESRD bundle.
Common Billing Challenges
These are the six billing failure points we see most often in nephrology practices — and the ones our team resolves systematically from day one.
Four or more documented visits earn the higher MCP tier; one to three visits pays typically half the full rate. Missing documentation of a fourth encounter costs the higher tier without anyone noticing.
Home hemodialysis and peritoneal dialysis patients still generate MCP payments — but only when oversight is documented. They slip through billing when the EHR doesn't flag them separately from in-clinic patients.
Non-ESRD E&M, unrelated conditions, and surgical or vascular access services are separately billable — but the note has to explicitly state the service is unrelated to the renal disease, not just describe the visit.
Post-operative care after AV fistula or graft surgery falls within the surgical global period. Separate billing during that window needs a modifier showing a distinct, unrelated problem.
Billing fistuloplasty or thrombectomy codes without separate interventional nephrology credentialing is a compliance problem, not just a billing one — and it's a growing exposure as more nephrologists take on these procedures.
Overlapping billing for the same post-transplant service, from the same date, between the transplant surgeon and the managing nephrologist, is a common denial trigger that needs clear role documentation to avoid.
Key Procedure Codes
Our coders hold specialty-specific credentials and train continuously on the codes that drive the most revenue — and the most denials — in nephrology.
| CPT Code | Description | Common Issue |
|---|---|---|
| MCP (4+ Visits) | ESRD Monthly Capitation Payment, full rate | Requires 4+ documented physician visits per month |
| MCP (1–3 Visits) | ESRD Monthly Capitation Payment, reduced rate | Pays typically half the full monthly rate |
| 36818–36833 | AV fistula/graft creation and revision | Outside the ESRD bundle; global period applies post-op |
| 36901–36909 | Interventional access procedures | Requires separate interventional credentialing |
| 99490 / 99424 | CCM / PCM for CKD Stage 4–5 | Track and bill monthly care management time |
| 99221–99223 | Initial inpatient codes for AKI admissions | Document kidney-specific data reviewed and management plan |
