PA-CN Salary Guide 2026: Complete Earnings Analysis

What We Can and Cannot Say About CAQ Pay

Search results for nephrology PA earnings tend to blur three separate things: what PAs in general earn, what PAs working in nephrology earn, and what holders of the Certificate of Added Qualifications in Nephrology earn. Those are different populations, and the evidence supporting each is very different. This guide separates them honestly.

Here is the plain position: the issuing body, the National Commission on Certification of Physician Assistants (NCCPA), publishes the requirements, fees, content blueprint, and renewal rules for the Nephrology CAQ. It does not publish a verified salary figure or a documented pay premium attached to holding the certificate. Any article that quotes a precise "CAQ-Neph salary" or promises a specific percentage raise is extrapolating or inventing. This one will not.

If you are weighing the credential primarily as a financial decision, read this alongside our complete ROI analysis of the PA-CN certification and the PA-CN certification cost breakdown, which handle the investment side in more depth.

What the Certificate Actually Represents

"PA-CN" is the shorthand used on this site for NCCPA's Certificate of Added Qualifications in Nephrology. Holders use the designation PA-C, CAQ-Neph. It is a specialty credential layered on top of initial PA-C certification, not a replacement for it, and it is distinct from nephrology nursing certifications and from physician nephrology board exams. If you are new to the terminology, our explainers on what PA-CN certification is and what PA-CN stands for cover the naming.

The credential signals that you have:

• Maintained current PA-C certification and unrestricted licensure
• Accumulated at least 2,000 hours of nephrology practice inside a 4,000-hour total PA practice requirement
• Completed 75 nephrology-focused Category I CME credits, with at least 25 in the two years before applying
• Obtained an attestation from a collaborating physician or lead/senior PA who knows your nephrology practice
• Passed a 120-question closed-book specialty examination

That bundle of verified experience, education, and examined knowledge is the product you are selling to an employer. Whether an employer pays more for it is a separate question, and the answer varies by workplace.

The Real Drivers of Nephrology PA Compensation

Because the CAQ itself has no documented, standalone pay premium, the more useful question is which factors reliably shape a nephrology PA's income and where the credential can plausibly influence each one.

Notice the pattern: the CAQ rarely changes the base market rate on its own, but it can strengthen your position on role scope and credibility. A PA who can document verified nephrology expertise is easier to place in complex-patient roles than one whose specialty experience rests on a résumé alone. For the hiring side of this picture, see our overview of PA-CN jobs.

Where Nephrology PAs Work and How Settings Shape Pay

The NCCPA attestation form for this credential asks the signing physician or lead PA to confirm management of patients within at least one listed nephrology practice setting. Those settings are a useful map of where specialty PAs actually work:

Each environment compensates differently. Hospital-based inpatient roles often involve rounding schedules and coverage obligations, while outpatient clinic and dialysis-unit roles tend toward more predictable hours. Transplant programs can involve complex longitudinal follow-up and multidisciplinary coordination. We deliberately make no ranking claim among these, because we have no verified data to support one.

One practical point: the CAQ does not require employment in every nephrology subspecialty. A PA working primarily in outpatient chronic kidney disease management is fully eligible, provided the experience and attestation requirements are met. Review the full eligibility picture in our PA-CN requirements guide.

The Cost Side of the Ledger

Salary analysis is only half of any return calculation. The documented direct costs are modest relative to a PA income, but they are real and recurring.

The CME line is usually the larger hidden expense, since the price of credits varies widely by provider and many employers subsidize continuing education. If your employer funds CME as part of your benefits package, your marginal out-of-pocket cost may be small. If not, budget for it. Fee specifics and any updates are tracked in our certification cost guide, and you should always confirm current amounts on NCCPA's own site before paying.

Negotiating With a CAQ in Hand

If the certificate does not carry a published pay premium, how do you convert it into leverage? Think in terms of documented, negotiable items rather than a single raise percentage.

1. Ask what the employer already does. Some organizations have a stipend, bonus, or ladder step for specialty certification. Others do not. Ask during hiring or at your annual review rather than assuming.
2. Request CME and fee support. Exam fees, the optional practice exam, and the 75 or 125 CME credits are logical line items for an employer professional-development budget.
3. Tie the credential to scope. Frame the CAQ as supporting independent management of complex patients, such as chronic kidney disease progression or acute inpatient dialysis consults, which can justify a larger panel or additional responsibilities.
4. Use the attestation as evidence. A collaborating physician or lead PA already attests to your knowledge and performance. That endorsement is a concrete, shareable data point.
5. Time the conversation. Raise it when you pass, at a performance review, or when a role opens that benefits from specialty depth.

What the Exam Tests, and Why It Matters to Your Marketability

Employers who value the credential are, in effect, valuing the knowledge it verifies. The NCCPA content blueprint lists eleven medical content categories, weighted as follows:

The largest category is labeled Chronic Kidney Disease at 20%. Some third-party summaries label that same slice "Chronic Dialysis"; follow NCCPA's own heading, which is what appears above. Dialysis content sits primarily in the separate End-Stage Renal Disease / Dialysis category at 17%.

The blueprint also describes a separate task distribution that cross-classifies the same questions: History and Physical 7%, Diagnostic Studies 20%, Diagnosis 25%, Managing Patients 35% (covering health maintenance, clinical intervention, and pharmaceutical therapeutics), Applying Scientific Concepts 10%, and Legal/Ethical Issues and Emerging Topics 3%. These are not additional medical domains, and they should not be added to the content weights. They describe the type of thinking each question demands.

What this means for your market value: the heaviest weights track the bread-and-butter work of a clinical nephrology PA, such as staging and managing chronic kidney disease, running dialysis patients, and interpreting renal pathophysiology. An exam that tests the daily core of the job is a credible signal. For a category-by-category breakdown, see our guide to all 11 PA-CN content areas.

Sequencing Your Preparation Around the Domains

The exam is 120 multiple-choice questions in two 60-question blocks, 60 minutes per block, closed book, with no calculators, notes, or books. You cannot revisit questions in a finished block, so pacing and first-pass accuracy matter. Because the weights are unequal, schedule your time proportionally rather than evenly.

Use official materials first: NCCPA's sample nephrology questions with critiques and its optional practice exam are the most reliable guides to question style. For a fuller plan, see our PA-CN study guide, and for realistic expectations about difficulty, read how hard the PA-CN exam is. To rehearse under realistic conditions, try the PA-CN practice tests.

Ten-Year Economics: Maintenance and Career Longevity

The CAQ is valid for ten years as long as your PA-C certification and licensure stay current. Think of it as a ten-year commitment with a defined maintenance cost, not a one-time purchase.

• CME accumulation: 125 nephrology Category I credits earned during the cycle and submitted by the maintenance-exam application
• Maintenance exam: passing the specialty examination again, with three attempts permitted in years nine and ten under the May 2026 governing policy
• Format flexibility: maintenance can be taken at a test center or online; the online version keeps 120 questions but allows five minutes per question across roughly a six-week window, with references permitted and assistance from others prohibited

Because the online maintenance option is a maintenance-only convenience, initial testing still happens at Pearson VUE test centers. Plan your timeline using our exam dates and scheduling guide, and note that the initial CAQ process must be completed within six years of initiation.

From a pure earnings standpoint, the practical value of this long horizon is risk management: holding the credential through the cycle keeps a verified specialty marker on your record without requiring you to re-qualify from scratch. Whether that translates into higher pay is, again, between you and your employer.
