Nephrology billing across dialysis, ESRD & transplant care
Nephrology billing is one of the most operationally intensive specialties in revenue cycle management. ESRD and dialysis reimbursement depend on monthly capitation billing, strict visit frequency rules, age-based coding, and detailed clinical documentation accuracy requirements. Nephrology practices also manage recurring CKD care, vascular access procedures, transplant services, and chronic disease management across high patient volumes. Errors in dialysis, MCP billing, or CKD documentation can create major recurring revenue loss across hundreds of monthly encounters.

Why nephrology billing is complex?
ESRD Bundled Payment Complexity
The ESRD Prospective Payment System bundles dialysis services and routine care into a payment, requiring accurate MCP billing and bundle compliance to prevent reimbursement risk.
Monthly Capitation Payment (MCP) Code Selection
Medicare pays nephrologists through capitation payments for dialysis care. Incorrect MCP selection can trigger downcoding and reimbursement risk across ESRD patient panels.
Dialysis Facility vs. Physician Billing
Hemodialysis and peritoneal dialysis requires accurate separation of facility and services, correct CPT selection, and documentation supporting physician involvement for each encounter.
Vascular Access Procedure Coding
AV fistula and graft procedures including creation, thrombectomy, angioplasty, and revision require precise coding, modifier use, and documentation to prevent bundling and reimbursement loss.
Age-Based MCP Visit Frequency Tracking
ESRD MCP codes are tiered by patient age and monthly visit count. High-volume nephrology practices face billing complexity tracking visits and applying the correct MCP tier for each dialysis patient.
Injectable Drug Administration (TDAPA)
Separately billable injectable drugs including ESAs, iron preparations, and calcimimetics require precise J-code billing, correct billing units, and TDAPA compliance to prevent ESRD reimbursement loss.
Transplant and Post-Care Billing Complexity
Kidney transplant management spans evaluation, post-transplant care, and nephrology follow-up, each requiring accurate billing, care coordination, and documentation compliance standards.
High-Volume Chronic Care Documentation
Nephrology practices managing CKD patients generate recurring E&M services and care coordination, but capturing this revenue requires active patient tracking and documentation compliance oversight.
Core RCM services
The following nine core services form the foundation of AnnexMed’s standard RCM offering for every nephrology practice. Each service is customized to the high-frequency, bundled payment, and multi-setting billing workflows that define nephrology revenue cycle management.
Eligibility & Benefits Verification
We confirm patient insurance coverage, deductibles, co-pays, and network status before every nephrology encounter, including ESRD entitlement verification, Medicaid coordination, and confirmation for dialysis, vascular access, and transplant services.
Prior Authorization Management
Our team manages the full prior auth lifecycle for vascular access procedures, transplant evaluations, renal imaging, and injectable drug administration, from clinical documentation through payer submission and appeals to prevent denials.
Claims Submission & Tracking
We submit clean claims electronically across office, hospital, dialysis center, and surgical settings, monitoring every claim through its complete lifecycle and validating MCP codes, modifier application, and injectable drug billing before submission to prevent rejections.
Denial Management & Appeals
Every denied nephrology claim is reviewed, root-cause analyzed, and appealed with MCP verification, TDAPA billing support, vascular access coding documentation, and detailed medical necessity records to maximize recovery and prevent repeat payer denials.
Accounts Receivable (AR) Follow-up
Our AR specialists proactively pursue outstanding balances for dialysis services, procedural claims, transplant charges, and vascular access cases, keeping days in AR below industry benchmarks with targeted follow-up on MCP and procedural revenue.
Patient Statements & Collections
We manage the complete patient billing experience for nephrology practices, from clear, procedure-level statements to respectful collection follow-ups, improving collections while preserving long-term patient relationships in this chronic care specialty.
Payment Posting & Reconciliation
All insurance and patient payments are posted accurately and reconciled daily against expected reimbursements for dialysis, MCP, procedural, and drug services, including ESRD bundled payments and technical/professional payment splits.
Provider Credentialing
We manage provider enrollment and credentialing with all commercial, Medicare, and Medicaid payers, keeping contracts active and preventing claim delays across office and hospital-based services, dialysis centers, and surgical facilities.
Reporting & Analytics Dashboard
You receive real-time RCM performance dashboards covering collections by service type, MCP billing metrics, denial rates by procedure category, drug revenue tracking, AR aging, and reimbursement trends, giving visibility into your nephrology revenue cycle.
Specialty-Specific RCM services
Dialysis Billing (90935-90940 Series)
Hemodialysis billing requires accurate distinction between dialysis sessions with single, multiple, or no physician evaluations because reimbursement depends on physician involvement. We manage dialysis billing from patient records to ensure compliant coding, documentation, and accurate reimbursement for every encounter.
ESRD MCP Billing
Medicare pays nephrologists for ESRD patients through monthly capitation payments covering dialysis-related care instead of per-session billing. We manage MCP billing by selecting the correct code based on patient age and visit count while maintaining regulatory compliance that prevents denials and audit exposure.
Kidney Transplant Billing
Nephrology services for kidney transplant recipients include pre-transplant evaluation, post-transplant care, and transplant management with distinct billing codes and compliance standards. We manage transplant billing from pre-transplant workup through ongoing monitoring while coordinating with the transplant global period.
CKD Management Billing
CKD management billing covers E&M visits, lab interpretation, anemia management, and care programs for CKD stages 1-5 and dialysis patients. We capture billable services within each encounter — including EPO administration (J0885), CCM documentation, and ICD-10 CKD staging to support medical necessity and reimbursement.
Vascular Access Billing
AV fistula and graft procedures including thrombectomy (36831, 36833), fistula repair, angioplasty, and dialysis access creation generate revenue for nephrology practices. We code vascular access procedures from documentation, capturing services with correct modifier usage and bundling prevention.
Home Dialysis Billing (CAPD & CCPD)
Home peritoneal dialysis billing uses specific CPT codes for CAPD and CCPD, with monthly MCP codes covering physician management services for home dialysis patients. We manage home dialysis billing to ensure correct modality coding, CMS-compliant MCP billing, and accurate capture of dialysis training services when provided.
Renal Biopsy Billing (50200, 76942)
Percutaneous renal biopsy billing requires coding the biopsy procedure (50200) and ultrasound guidance (76942) separately with supporting documentation. We ensure renal biopsy claims capture both components accurately, preventing incomplete billing and protecting revenue from this commonly performed nephrology procedure.
Hypertension Coding
Nephrology E&M visits for resistant hypertension and complex electrolyte disorders require high-level medical decision-making documentation. We ensure nephrology E&M billing reflects complexity, applying current AMA E&M guidelines to maximize reimbursement across high-frequency chronic care patient populations.
ICD-10 Nephrology Codes
Nephrology ICD-10 coding requires accurate CKD staging, AKI differentiation, and correct ESRD status coding that drives Medicare ESRD billing. Our certified nephrology coders ensure coding specificity and accuracy to support medical necessity, reduce payer denials, and prevent compliance risks across CKD and ESRD claims.
