Keep authorization and coverage aligned before the appointment is booked.
Master ESRD bundle billing, dialysis facility fee splits, and CKD progression documentation. See why nephrology practices choose Unlimited Systems for practice management and RCM software.
Nephrology practices face uniquely complex billing environments spanning outpatient CKD management, inpatient acute kidney injury consultations, vascular access procedures, and the heavily regulated ESRD Prospective Payment System bundle.
The ESRD PPS bundle consolidates over 50 previously separate services into a single per-treatment rate. Failing to properly document excluded services or correctly split professional and facility fees leads to catastrophic revenue compression that generic systems cannot prevent.

Our connected workflows are built to make you and your work easier to do and increase your revenue.
Keep authorization and coverage aligned before the appointment is booked.
Validate nephrology codes, modifiers, and documentation before submission.
Give teams one view of denials, margin, and A/R priorities.
ESA and iron therapy billing complexity makes dialysis-adjacent RCM uniquely challenging.
Where revenue is at risk
Aranesp and Epogen are heavily scrutinized by CMS and require hemoglobin monitoring documentation.
How the platform addresses this
| Drug | Code | Route | Channel | Cost | PA | Billing notes |
|---|---|---|---|---|---|---|
| Aranesp (darbepoetin) | J0881 / J0882 | SQ/IV | Part B | $8K/yr | Yes | Hgb threshold documentation required each visit. |
| Injectafer (ferric carboxymaltose) | J1439 | IV | Part B | $3K/course | Sometimes | Two-dose protocol; single-use vial JW required. |
| Venofer (iron sucrose) | J1756 | IV | Part B | $1K/yr | No | Multi-dose vial; partial dose tracking needed. |
| Parsabiv (etelcalcetide) | J0606 | IV | Part B | $6K/yr | Yes | 3x/week dialysis dosing; bundle exclusion critical. |
| Monoferric (ferric derisomaltose) | J1437 | IV | Part B | $2K/course | Sometimes | Newer; single-dose; JW required. |
Cabinet integration: Dialysis-adjacent nephrology practices using in-office IV therapy rely on accurate dispensing records. Without ADC integration, ESA dose tracking across visits fails audits, especially for Hgb threshold compliance.
Specialty practices describe, in their own words, what changed after moving to Unlimited Systems.

“As I look back at the transition, the support and the collaboration with the folks at Unlimited really helped make us feel at ease. We had a partner that really wanted us to be successful.”

These are the places nephrology practices most often lose revenue when their billing platform wasn’t built for the work. Unlimited Systems closes each one with rules configured for your specialty.
Review your workflowCommon nephrology revenue leaks
The work that generic platforms leave to your staff is the work nephrology margin actually turns on.

See why nephrology practices move off general-purpose billing platforms.
You don't have to be actively replacing your current system to have a useful conversation with Unlimited Systems. Many nephrology practices talk with us months before a contract renewal or system evaluation to understand where ESA documentation, iron therapy billing, lab-value support, and dialysis-related complexity may already be showing up.
A conversation can help surface where ESA hemoglobin documentation, iron infusion dosing and wastage, TSAT/ferritin lab support, and bundle-versus-fee-for-service decisions may be creating audit and denial exposure.
Specialty rules and connected data keep your team focused on the exceptions that need judgment.
Coverage and authorization stay tied to the order.
Code, unit, and modifier checks happen before filing.
Denials and A/R are ranked by value and filing risk.
The same connected system handles the operational work that sits either side of billing.

Explore Charge ValidationEight stages, one record. Nothing is rekeyed between systems, so a detail captured at the front desk is still there when the claim goes out, and when the remittance comes back.
Walk the workflow with usWe maintain a continuously updated excluded services list aligned with the CMS ESRD PPS final rule, automatically routing excluded drugs, labs, and supplies outside the bundle for separate billing.

That's putting it nicely based on what we hear every day.
A support line that never picks up. An overseas call center that's never heard of your account. Errors nobody catches until the denial shows up. We're Midwest-based, not offshore, and the team that answers already knows your account. Practices that switch tend to wish they'd done it sooner.
