Nephrologist Salary, Hourly Rates, and Locum Income

What Is the Average Nephrologist Salary?

Most nephrologists earn between $367,000 and $400,000 annually, depending on practice model, geography, and clinical volume.

That range is driven primarily by:

• Dialysis and inpatient coverage
• Practice ownership structure
• Call burden and procedural work

National Salary Benchmarks

Why Nephrology Salaries Vary

• Doximity draws from a self-reported panel of over 37,000 physicians and publishes a nephrology-specific median.
• Medscape surveys over 7,300 physicians and reports average total compensation including bonuses and profit-sharing.
• SalaryDr aggregates crowdsourced submissions with a smaller sample (31 physicians for nephrology as of April 2026), which introduces more variance but often captures higher-earning independent contractors that larger surveys undercount.

The honest read is a range with context. For a W-2 employed nephrologist working a standard clinical load, $350,000 to $400,000 captures the realistic band. Independent contractors and physicians in high-demand markets can exceed that ceiling.

Specialization Paths That Influence Compensation

Nephrology is already a subspecialty of internal medicine, but further focus areas within nephrology can shift the income profile.

• Transplant nephrology commands a premium at academic medical centers and large transplant programs, though the premium is driven more by institutional value than by published salary benchmarks.
• Interventional nephrology (dialysis access procedures, tunneled catheter placement) adds procedural revenue that can meaningfully increase total compensation in practice models that compensate per procedure.
• Critical care nephrology opens ICU-based roles with higher acuity and often higher pay, particularly at facilities running continuous renal replacement therapy programs.
• Onco-nephrology is an emerging niche connecting kidney toxicity management with oncology treatment protocols. Compensation impact is limited today but growing as the field matures.

Nephrology Salary by Practice Model

Practice structure matters significantly in nephrology. Employed physicians generally operate within stable compensation bands, while physicians with ownership stakes in dialysis centers, nephrology groups, or ancillary services can generate substantially higher long-term income.

That gap becomes especially meaningful in mature dialysis-heavy markets.

What a Full-Time Clinical Load Looks Like in Nephrology

Nephrology combines outpatient clinic care, inpatient consults, dialysis rounding, and longitudinal chronic disease management into a relationship-driven specialty. Most nephrologists balance clinic schedules with hospital coverage and dialysis responsibilities, with workload intensity increasing alongside patient complexity and call burden.

Unlike shift-based specialties, nephrology income compounds through long-term patient management and recurring dialysis care relationships.

Nephrology Workforce Trends

Nephrology compensation has been trending upward. Doximity’s 2025 report shows a 3.7 percent year-over-year increase (data year 2024), while Medscape’s 2025 report reports a 3 percent increase. Both trends align with broader patterns across internal medicine subspecialties.

The supply picture is the more important story. Nephrology has faced a well-documented pipeline challenge for over a decade: fellowship positions go unfilled at higher rates than most internal medicine subspecialties, and the practicing nephrologist workforce is aging. AAMC physician workforce data projects continued tightening through 2036.

The demand side compounds the supply gap. Chronic kidney disease prevalence continues to rise alongside the aging U.S. population, and the expanding use of dialysis and kidney transplantation increases the clinical volume each practicing nephrologist absorbs. These forces are structural, not cyclical, and they underpin both compensation growth and sustained locum demand.

Nephrology Locum Tenens Income Potential

Locum tenens rates for nephrologists range from $125 to $200 per hour depending on assignment type, geography, and urgency. The scenarios below use representative rates from within that band based on a clinical load of approximately 40 hours per week.

Locum nephrology gives physicians more control over schedule, geography, and workload while maintaining stable earning potential.

To exceed $450K:

• Add dialysis-access procedures
• Increase inpatient and call coverage
• Target underserved dialysis markets

What 1099 Physicians Actually Take Home

Higher locum rates create more than additional income potential. 1099 nephrologists gain flexibility in how income, taxes, geography, and workload are structured over time.

While independent physicians manage their own benefits, retirement planning, and taxes, they also gain access to advantages unavailable in most employed models, including business deductions, larger retirement contribution limits, the Qualified Business Income deduction, and S-corp tax optimization at higher income levels.

For many nephrologists, the larger shift is control. Schedule, patient mix, dialysis coverage, and geography become variables they can actively design around their career goals.

Most physicians do not optimize this alone. Barton partners with Earned, a wealth and tax firm built specifically for doctors, to give locum clinicians entity formation, tax planning, and long-term financial strategy designed around how physicians earn.

Nephrology Career Trajectory

Nephrology follows a predictable compensation arc after fellowship. Early-career nephrologists entering W-2 employed positions typically start in the low-to-mid $300,000 range, with the trajectory depending heavily on practice model and geography.

• Years 1 to 3 (post-fellowship): Building patient panels, establishing dialysis center relationships, and completing any remaining board certification requirements. Compensation is often at or slightly below the national median during this period.
• Years 4 to 8: Panel maturity, procedural volume growth (for interventional nephrologists), and the first meaningful decision point between staying employed and transitioning to private practice or partnership. Compensation typically reaches or exceeds the $367,000 to $400,000 band.
• Years 8 and beyond: The highest-earning nephrologists at this stage are typically practice owners, partners in multi-physician nephrology groups, or physicians with ownership stakes in dialysis facilities. Locum work becomes increasingly attractive for nephrologists in this tier who want to maintain income while reducing administrative burden.

Choosing a Locum Tenens Partner You Can Trust

The locum industry has a baseline problem. Smaller or less established agencies routinely cut corners that cost physicians real time and real money: credentialing delays that push start dates, licensing gaps that leave physicians exposed, malpractice coverage that turns out to be less than it looked, and invoices that drag on after the assignment ends.

Barton Associates differentiates on three verified features.

• Physician-led clinical leadership. Barton has a Chief Medical Officer and physician-led clinical oversight, a structure that is unheard of in the locum staffing category.
• Earned partnership for physician financial life. Barton partners with Earned, a wealth and tax firm built specifically for doctors, to give locum clinicians access to entity formation, tax planning, and long-term financial strategy designed around physician income.
• Reflective-practice continuing medical education platform. Barton operates a continuing medical education platform built around reflective practice on clinical work physicians are already doing.
