Is Your Nephrology Practice Leaving Money on the Table?
Most nephrology practices lose 10-18% of collectible revenue every month - from ESRD billing errors that are completely preventable.
MCP Visit Miscounting
One undocumented monthly visit drops your ESRD payment per patient by 20-25%. Billing 90960 when only two visits are on record is not just lost revenue - it triggers retroactive recoupment when payers audit your panel.
ESRD Bundling Violations
Billing dialysis sessions (90935, 90937) inside an MCP month without understanding bundle boundaries creates overpayment liability and audit exposure on every single claim - even ones coded correctly.
CKD Stage Coding Errors
Unspecified CKD codes trigger automatic payer rejections. N18.1 through N18.6 must match documented stage exactly. Combined codes like I12.0 for hypertensive CKD routinely get submitted as two separate codes - denied every time.
Dual Eligibility Chaos
The 30-month Medicare secondary payer rule catches practices every year. Employer plans pay primary for the first 30 months after ESRD diagnosis. Wrong COB sequencing means chronic rejections on otherwise clean claims.
Collection Rate Comparison
Our nephrology clients recover an average of 18% more revenue within the first 90 days of going live.
Everything Your Nephrology Practice Needs to Get Paid Right
From ESRD monthly management to the last dollar collected, we handle your entire nephrology revenue cycle so you can focus on kidney care.

ESRD Monthly Management
We track every patient's face-to-face visits throughout the month and select the correct MCP code (90960, 90961, 90962) based on documented visits. One miscounted visit costs 20-25% of monthly patient revenue. We catch it before submission.
Get Started
Prior Authorization & Vascular Access
Vascular access procedures require pre-authorization with most payers. We manage every auth from submission to renewal, track expiry windows, coordinate rescheduling if approval delays arise, and ensure zero procedure interruptions for your patients.
Get Started
Dialysis & Procedure Coding
Certified nephrology coders handle hemodialysis (90935, 90937), peritoneal dialysis (90945, 90947), vascular access (36821, 36832), and all associated modifiers. Every ESRD bundle boundary tracked. Zero accidental unbundling.
Get Started
CKD Coding & Charge Entry
Accurate ICD-10 staging (N18.1-N18.6), correct combination codes (I12.0 for hypertensive CKD, E11.22 for diabetic nephropathy), and complete diagnosis sequencing per payer. Unspecified CKD coding is the fastest route to a payer audit - we eliminate it.
Get Started
Denial Management & Appeals
ESRD bundling denials, MCP visit-count mismatches, dual eligibility rejections - we investigate every denial, build appeals with complete documentation, and resubmit. More than 70% of properly appealed nephrology denials get paid.
Get Started
AR Follow-Up & Collections
Systematic follow-up across Medicare, Medicaid, dual-eligible, and commercial payers. Every claim tracked against timely filing windows. We prevent ESRD write-offs before the filing deadline closes - permanently.

"Working with Sirius Solutions Global has completely transformed our billing process. Their expertise, transparency and dedication helped us increase collections while reducing administrative stress. We can now focus more on our patients, knowing our revenue cycle is in expert hands."
"Our front desk used to spend hours chasing insurance authorizations and untangling modifier issues. Since switching to Sirius, they actually have time for patients. Our denial rate dropped, collections are up, and I can see exactly where every dollar stands."
"Our ESRD claims were getting denied constantly - MCP codes didn't match documented visit counts and no one was catching it. Sirius corrected everything within weeks. Medicare revenue jumped over 22%."
"Three nephrologists billing across two dialysis centers - the bundling errors were silently eating our revenue every month. Sirius standardized everything, cut our AR days from 52 to 19, and the MCP reports finally make sense."
"My team was systematically underbilling on ESRD patients - wrong MCP codes, missed CCM billing, incomplete dialysis documentation. Sirius ran an audit and found tens of thousands I was leaving on the table every month."
