Nephrology Billing

Nephrology Billing Services That Protect Your Kidney Care Revenue

Nephrology billing operates under a reimbursement framework unlike any other specialty: ESRD patients are billed under a monthly capitation model that covers most dialysis-related services, while unrelated services must be identified and billed separately. CKD staging requires ICD-10 specificity that directly affects reimbursement. AV fistula and graft access procedures carry high claim values with their own documentation requirements. ProtoMed's certified nephrology billing specialists handle every claim with the precision your practice demands. Fewer denials. Faster reimbursements. More revenue.

Stop Losing Nephrology Revenue to ESRD Billing Errors and CKD Staging Gaps

Nephrology billing requires fluency in two completely different reimbursement models operating simultaneously. For ESRD patients on dialysis, Medicare pays a monthly capitation rate that bundles most dialysis-related services, and billing separate E/M visits for dialysis-related care during the capitation period is a compliance error. But E/M visits for conditions unrelated to ESRD are separately billable, and correctly identifying and separating dialysis-related from unrelated services is where most nephrology revenue is either lost or placed at compliance risk. For CKD patients not yet on dialysis, ICD-10 staging codes (N18.1 through N18.6) must be documented with full specificity: CKD stage affects risk adjustment, care management billing eligibility, and payer reimbursement rates.

ProtoMed's certified nephrology billing team understands the full complexity of kidney care billing: ESRD monthly capitation versus per-visit billing models, dialysis-related versus unrelated service separation, AV access procedure coding, CKD staging specificity, and the recurring care management services that most nephrology practices under-capture. We submit clean claims, manage the ESRD billing framework correctly, and follow up on every denial so your practice collects what it has earned.

Procedure-Specific Billing

Specialized Billing for Every Nephrology Service

Nephrology billing demands fluency in the ESRD capitation framework, precise CKD staging documentation, AV access procedure coding, and care management billing, all simultaneously. ProtoMed's certified team handles every service correctly across the full kidney care billing spectrum.

ESRD Monthly Capitation Billing

ESRD patients on dialysis are reimbursed under a monthly capitation model: a single monthly payment covers all dialysis-related services for the month. The correct G-code depends on whether the patient dialyzes at home or in-facility, and the per-visit threshold determines which code applies. E/M visits during the capitation period for dialysis-related conditions must not be billed separately. We manage ESRD capitation billing correctly, apply the right monthly codes, and protect your practice from compliance errors on the most high-volume billing in nephrology.

Dialysis-Related vs Unrelated Service Billing

The most important billing distinction in nephrology is whether an E/M service is related to or unrelated to the patient's ESRD. Services for hypertension management, anemia of CKD, and mineral metabolism are typically bundled into the ESRD capitation payment and cannot be billed separately. Services for acute conditions unrelated to kidney disease, infections, musculoskeletal complaints, cardiac events, are separately billable E/M visits. We correctly classify and bill every nephrology encounter within the ESRD framework, capturing all separately billable revenue while maintaining compliance.

AV Fistula & Vascular Access Billing

Arteriovenous fistula creation, graft placement, revision, and thrombectomy procedures are high-value claims that require precise code selection based on the specific procedure performed, the access site, and whether the procedure is a new creation or revision. Imaging guidance codes must be billed separately when used. We accurately code every AV access procedure, apply the correct laterality modifiers, and include imaging guidance add-on codes when applicable, capturing the full reimbursement value of every vascular access case.

CKD Staging & ICD-10 Coding

CKD staging specificity in ICD-10 affects multiple revenue streams simultaneously: HCC risk adjustment for Medicare Advantage patients, CCM billing eligibility, and payer-specific reimbursement rates. Documenting "CKD" without specifying the stage (N18.1 through N18.6) leaves risk-adjustment revenue on the table and may prevent CCM billing eligibility. We ensure every CKD encounter captures the documented GFR-based stage with full ICD-10 specificity, protecting both reimbursement and compliance across your entire CKD patient panel.

CCM & Care Management Billing

CKD patients, especially those in stages 3-5, frequently qualify for Chronic Care Management billing, representing $80-$140 per patient per month in recurring revenue. Monthly time tracking, care plan documentation, and patient consent are required. Transitional Care Management applies when CKD or ESRD patients are discharged from a facility. We manage the complete CCM and TCM billing cycle for your nephrology patient panel, capturing this recurring revenue stream without adding clinical burden to your team.

Kidney Transplant Follow-Up Billing

Post-transplant care involves high-complexity E/M visits, immunosuppression management, and close monitoring of transplant function, each billed under specific codes that differ from standard nephrology E/M visits. Transplant evaluation services for living donors require separate coding. We accurately code every transplant evaluation and follow-up encounter, ensuring the complexity of post-transplant management is captured at the correct E/M level with the documentation required to support each claim.

Our Process

How ProtoMed's Nephrology Billing Process Works

A structured four-step process that manages the ESRD capitation framework correctly, captures all separately billable services, and maximizes care management revenue across your kidney care patient panel.

01

Practice Audit & Revenue Gap Analysis

We review your current nephrology billing setup, identify revenue leaks from ESRD capitation errors, missed separately billable services, CKD staging specificity gaps, unclaimed CCM revenue, and unresolved denials, then securely access your existing EHR with zero disruption to your clinical operations.

02

Patient Panel Review & Care Management Enrollment

We review your CKD patient panel, identify CCM-eligible patients who are not currently enrolled, document CKD staging specificity for HCC risk adjustment, and verify ESRD eligibility and dialysis modality for correct monthly capitation code selection. Proactively identifying care management billing opportunities creates recurring revenue that most nephrology practices miss entirely.

03

Claim Coding, Scrubbing & Payer Submission

Our certified nephrology coders review every encounter, apply the correct ESRD capitation codes or per-visit dialysis codes, correctly classify dialysis-related versus unrelated E/M visits, code CKD with full ICD-10 stage specificity, and apply AV access procedure codes with imaging guidance add-ons where applicable. Claims are submitted electronically on time to Medicare, Medicaid, and all major commercial payers.

04

Denial Management, Payment Posting & Reporting

Every denied claim is investigated, corrected, and appealed with the clinical documentation required for reversal. Payments are posted accurately, CCM time logs are tracked monthly, and you receive clear monthly reports on your capitation revenue, separately billable service collections, care management income, and denial patterns by payer.
