Nephrology medical billing relies on MCP visit-tier accuracy, ESRD PPS bundle knowledge, Medicare Secondary Payer tracking, and CKD staging that passes payer review. MedCare MSO combines AAPC-certified renal coders with AI-powered claim validation to help submit accurate, payer-ready dialysis, CKD, and vascular access claims the first time.
Talk to a Renal Billing ExpertPayers now regularly audit MCP visit documentation, and incomplete notes can affect the tier supported for that month's claim. Practices managing dialysis panels need nephrology medical billing services that are built around capitation rules and payer coordination. Practices that outsource nephrology billing services to a specialty team keep those recurring monthly claims clean from the start.

Your revenue pools up from four different payment systems at once: monthly capitation, the facility bundle, fee-for-service procedures, and payer coordination rules. Each one denies claims for its own reasons, so our nephrology medical billing services handle each one on its own terms. Here is what we manage for you.
Medicare pays outpatient ESRD management through one monthly capitation code tiered by age band and visit count. Missing out on one note drops the tier every month. Our dialysis billing services reconcile visit counts against rounding logs before any MCP claim is sent out. Our team applies the home-dialysis monthly codes where they belong and switches to the daily codes when a partial month makes the monthly code unbillable.
A CKD stage with an incomplete clinical record creates coding inconsistencies and increases denial risk. Our coders validate staging against the clinical record before submission, apply the hypertension combination coding and dialysis-dependence status each claim requires, and confirm the diagnosis-to-procedure linkage payers audit, so medical necessity is proven on the claim itself. That pre-submission discipline is what careful nephrology billing and coding looks like in practice.
For ESRD patients with employer group coverage, the group plan pays primary for 30 months, then the order reverses, and claims sent to the wrong primary are denied or recouped. We track every patient's coordination-period start date, verify MSP status at each eligibility check, route every claim to the correct primary, and monitor the flip date; accurate ESRD billing depends on this tracking.
The ESRD PPS pays facilities one bundled rate per treatment, covering dialysis, ESRD-related drugs, labs, and supplies. Our nephrology medical billing services audit facility and professional claims side by side, claim physician MCP services, vaccines, and non-ESRD items outside the bundle, and bill drugs in their TDAPA window correctly, so nothing billable is lost inside it.
Injectable drugs like ESAs, iron preparations, and calcimimetics demand precise J-code billing and TDAPA compliance. We track each TDAPA window as it opens and closes, verify bundle status per drug as CMS updates the list each year, and apply correct units on every claim, so drug revenue is neither unclaimed nor recouped.

Our certified coders work the full nephrology code set. Dialysis session and monthly management codes, vascular access interventions, biopsy and transplant work, and the labs and imaging ordered around them are all coded to current AMA and CMS guidance. That code-level discipline is what separates specialty nephrology billing and coding from a team working fifty specialties on rotation, and it is the backbone of our nephrology billing services. Pick a code family below.
| Billing Area | Detail & MedCare MSO Approach |
|---|---|
| Claim Submission | UB-04 for ESRD facility claims; CMS-1500 for nephrologist monthly capitation and physician visits, with claim scrubbing and compliance checks before every submission. |
| Dialysis Session Coding | 90935/90937 (hemodialysis) and 90945/90947 (peritoneal or other dialysis); code selection driven by the single vs. repeated evaluation documented in the session note. |
| Monthly ESRD Management | 90951–90962 (in-center) and 90963–90966 (home dialysis); selected by age tier and face-to-face visit count, with visit documentation verified before billing the higher-tier code. |
| Partial-Month Billing | 90967–90970 billed per day by units for transient patients, mid-month modality changes, hospitalizations, and transplant months. |
| ESRD PPS Bundling | Per-treatment composite rate covering the dialysis procedure, most drugs, labs, equipment, and consumables; MedCare MSO screens every claim for bundle inclusions to prevent duplicate billing denials. |
| Unbundled & Separately Payable Items | Calcimimetics (J0606/J0607) and eligible non-ESRD drugs identified and captured outside the bundle so reimbursable dollars are not absorbed into the composite rate. |
| Vascular Access Procedures | Dialysis circuit hierarchy 36901–36906 plus central segment add-ons 36907–36909; angioplasty and imaging bundling rules applied per session, with NCCI edits run before submission. |
| Biopsy & Transplant Coding | 50200 with separately coded imaging guidance; 50360/50365 recipient transplant coding with co-surgeon and global-period rules applied. |
| Modifier Accuracy | Modifiers 25, 59, 76, and 91 applied where documentation supports them; the most frequent cause of nephrology denials audited on every claim. |
| Denial Prevention & Appeals | Single vs. repeated evaluation mismatches, MCP visit-count documentation gaps, circuit bundling edits, and medical necessity for access interventions; denials appealed, not absorbed |
| Regulatory Compliance | CMS ESRD billing guidelines, ESRD PPS annual rule, NCCI edits, and HIPAA; MedCare MSO maintains full audit-ready documentation on every claim |
MedCare MSO links every study to the renal diagnosis that establishes medical necessity before the claim is submitted.
Code descriptors reflect current AMA CPT and ICD-10-CM. ICD-9-CM was retired on October 1, 2015 and does not apply to current claims. Our nephrology medical billing solutions verify payer coverage and edits against the specific plan before every submission.
Each area of kidney care carries its own coding guidelines and payer requirements. Our nephrology medical billing solutions adapt to every subspecialty's documentation patterns, including internal medicine and nephrology groups that split time between primary care and renal medicine.
We bill staged chronic kidney disease and end-stage renal disease care across in-center, home, and transitional dialysis, and our dialysis billing services apply the monthly management coding that goes with each modality.
We code hypertensive kidney disease alongside fluid, electrolyte, and mineral and bone disorders, using the combination logic payers expect for CKD-related management.
We handle glomerular disease, nephrotic syndrome, proteinuria, and diabetic kidney disease, where the diagnosis-to-service linkage on each claim drives medical-necessity acceptance.
We bill AKI management in the hospital and AKI dialysis furnished in certified ESRD facilities, each under the correct type of bill and code set.
We cover transplant recipient and donor services and post-transplant management, with the E/M and procedure coding each phase of the transplant journey requires.
We manage pediatric age-tier MCP coding, where a patient's birthday changes the correct code, and the interventional nephrology and dialysis access work handled by the practice.
Your patients move between the office, the hospital, the dialysis unit, and their own homes. Your claims have to move with them, and every setting changes how the claim is built and who it goes to. We handle that routing for you:
Facility claims run on their own track. ESRD facilities bill on the UB-04 under the 72X type of bill, the identifier for renal dialysis facility claims. So every month, one patient produces two claims: the facility's 72X and your professional MCP claim. We reconcile both streams before submission, so neither one triggers a denial on the other and you get paid on each.

Nephrology denials cluster around a handful of predictable causes: MCP claims missing visit-count documentation, MSP coordination errors, absent or mismatched CKD staging, vascular access bundling edits, and eligibility gaps at the dialysis facility. Our nephrology revenue cycle management workflow scrubs for all of them before submission, then works every denial that does occur through root-cause analysis, corrected claims, and payer appeals via our denial management services.
For balances already aged past 60-90 days, our dedicated AR recovery services team pursues old claims that in-house staff rarely have time to touch.
Kidney care runs on high-cost drugs and procedures that payers gate behind authorization: ESA medications for anemia of CKD, IV iron infusions, imaging, vascular access interventions, and transplant workups. We verify eligibility and MSP status before the visit, secure authorizations before the service, and track expirations so refills and repeat treatments never lapse into denials. This front-end discipline is where nephrology medical billing solutions protect revenue before a claim even exists.
Add a single AI product that fixes your biggest bottleneck, or integrate the complete AI Ecosystem into your billing. With monthly capitation, an error repeats twelve times a year per patient, so four connected products power our nephrology medical billing solutions from the rounding note to the posted payment.
Our electronic health record system syncs nephrology clinical records with billing and coding, from office CKD visits to dialysis rounding.
Our AI Medical Scribe captures your nephrology patient visits as structured clinical documentation, including the visit counts and CKD staging details that drive MCP tiers.
MedCare MSO's AI Coder assigns nephrology CPT, ICD-10, and HCPCS codes with the right modifiers, flagging missing CKD stages before a claim is created and keeping your nephrology billing and coding audit-ready.
MedCare MSO's practice management system runs nephrology scheduling, charge entry, claim submission, and claim status from one platform.
Our nephrology medical billing solutions are scoped to the setting, because a solo CKD practice, a dialysis organization, and a hospital program do not bill the same way.
Nephrology Practices & Groups
Solo nephrologists, single-specialty groups, and internal medicine and nephrology practices. We handle office E/M, CKD staging, MCP panels, and the payer mix of a community practice, scaled to any provider count.
Dialysis Centers & ESRD Programs
In-center and home dialysis programs billing on the 72X, with PPS bundle management, adequacy reporting, TDAPA drug billing, and monthly reconciliation between facility and physician claims.
Interventional Nephrology & Access Centers
Office-based labs and access centers performing fistulagrams, angioplasty, stenting, thrombectomy, and catheter procedures, where circuit-code hierarchy and NCCI bundling decide whether the claim pays.
Hospital & Transplant Nephrology
Inpatient consult services, hospital dialysis rounds, AKI management, and transplant programs, with the place-of-service accuracy, global-period tracking, and co-surgeon rules these claims require.
MIPS performance adjusts your Medicare payments up or down, and kidney care has quality measures your reporting should actually reflect. We help your practice select the measures that fit its patient mix, capture quality data inside the billing workflow rather than as separate chart abstraction, and support reporting through a qualified clinical data registry (QCDR) or the Optimal Care for Kidney Health MVP where those fit better than traditional MIPS. On the compliance side, coding audits, documentation reviews, and HIPAA-compliant processes keep the revenue you collect defensible under payer and CMS review.
Reconciling an MCP claim against a facility's 72X, defending a visit tier under audit, and routing a claim through the MSP 30-month coordination period are daily tasks for our team. As a top nephrology medical billing company, MedCare MSO gives practices that outsource nephrology billing services specialty-trained staff backed by the infrastructure we bring to 50+ specialties:
In 2023, DT Nephrology was losing revenue to unworked claims, modifier errors, and services that were never billed. As their nephrology billing company, we stepped in and rebuilt their revenue cycle management end-to-end. Here is exactly what we fixed.
Hospital and dialysis center claims sat unworked, incorrect modifiers drove denials, and services were delivered but never billed due to no reconciliation process.
With denials cut to 2–5%, Days in A/R at 30–40 days, and 95% of payments posted via ERA.
| Metric | Before | After | Improvement |
|---|---|---|---|
| Monthly Collections | Lost & delayed revenue | $28,000 | Revenue Growth |
| Denial Rate | Frequent modifier denials | 2–5% | Significant Drop |
| Days in A/R | Claims sat unworked | 30–40 days | Stable Cash Flow |
| Payment Tracking | No reconciliation | 95% ERAs | Automation Gain |
Coding, submitting, and collecting claims for kidney care: dialysis, CKD and ESRD management, vascular access, transplant, and related labs. Medicare pays much of it through capitation and bundles, so practices choose dedicated nephrology medical billing services in USA with full nephrology revenue cycle management behind them.
Inpatient hemodialysis uses 90935 and 90937. Peritoneal and other non-hemodialysis procedures use 90945 and 90947. Monthly ESRD management bills use MCP codes 90951-90966, partial months use 90967-90970, and dialysis training uses 90989 and 90993.
Both report dialysis other than hemodialysis. 90945 applies when the physician performs a single evaluation during the procedure; 90947 requires repeated documented evaluations. The documentation, not the number of sessions, selects the code.
Codes 90951-90962 pay one monthly amount tiered by age band and face-to-face visits: four or more, two to three, or one. Home dialysis uses 90963-90966 monthly; partial months use daily codes 90967-90970.
The 72X identifies institutional claims from ESRD facilities on the UB-04. Physician services never go on a 72X; they bill separately under MCP codes, so facility and physician claims must be reconciled monthly.
With employer group coverage, the group plan pays primary for 30 months, then Medicare becomes primary. Claims routed to the wrong primary are denied or recouped, so accurate ESRD billing means tracking each patient's coordination start date.
N18.1-N18.6 report stages 1 through 5 and ESRD, with stage 3 split into N18.31 and N18.32, matched to the documented GFR. Hypertension takes I12/I13 combination coding, and dialysis dependence takes Z99.2.
Modifier 25 for a separate same-day E/M, AY for non-ESRD items payable outside the bundle, G1-G6 for URR reporting, and CD/CE/CF on AMCC labs. Incorrect modifiers drive many denials in nephrology billing and coding.
Yes, the circuit family 36901-36909, AV fistula and graft creation, dialysis catheter placement and exchange, and peritoneal catheter insertion, with every claim scrubbed against current NCCI edits before submission.
Yes. We authorize ESAs, IV iron, imaging, and procedures; verify eligibility and MSP status pre-visit, and run full denial management with appeals. Our nephrology medical billing solutions cover the cycle end-to-end for practices that outsource nephrology billing services.
