GI Physician Salary in the United States
A GI physician, more formally called a gastroenterologist, is a physician who specializes in diagnosing and treating diseases of the digestive system. The specialty covers conditions involving the esophagus, stomach, intestines, liver, gallbladder, pancreas, colon, and rectum.
Gastroenterologists work in private medical groups, hospitals, academic health systems, outpatient endoscopy centers, and government health systems such as the Veterans Health Administration. Because compensation differs substantially by employer and location, there is no single nationwide paycheck that represents every gastroenterologist.
This 2026 guide separates private-sector, federal-government, and state/local-government compensation and explains the factors that can make the final financial picture very different from the advertised salary.
Who Is a GI Physician?
A gastroenterologist evaluates patients with digestive-system disorders and performs procedures such as upper endoscopy and colonoscopy. Depending on the practice, the physician may also treat liver disease, inflammatory bowel disease, gastrointestinal bleeding, pancreatic disorders, and other complex conditions.
The job is found across all three major employment sectors. Private employers include hospitals, physician groups, health systems, and ambulatory surgery/endoscopy centers.
Federal opportunities are concentrated particularly in the VA health system, while state and local positions can exist in public hospitals, university medical centers, county health systems, and other publicly operated facilities.
GI Physician Salary
For most U.S. gastroenterologists, the private sector offers the widest range of compensation. Current 2026 market estimates illustrate why it is important to distinguish base salary from total compensation.
Salary.com reported a September 2026 national average of $436,600 for gastroenterologists, with a 25th-percentile salary of $410,400, a 75th percentile of $482,300, and a 90th percentile of $523,907. These are salary estimates rather than guaranteed employment offers.
Doximity’s 2026 Physician Compensation Report reports $531,345 in average compensation for gastroenterology. That figure represents physician compensation rather than simply a guaranteed base salary, so it should not be compared directly with a base-salary figure.
Private-Sector Salary Structure
| Compensation component | 2026 figure / treatment |
| 25th-percentile salary | $410,400 (Salary.com) |
| Average salary | $436,600 (Salary.com) |
| 75th-percentile salary | $482,300 (Salary.com) |
| 90th-percentile salary | $523,907 (Salary.com) |
| Average physician compensation | $531,345 (Doximity, 2026 report) |
| Bonus/incentive | Variable; depends on contract, productivity and quality measures |
| Partnership/profit distributions | Variable; applicable in some private practices |
| Equity | Employer/practice-specific; not universal |
A major distinction is productivity-based compensation. Some contracts combine a guaranteed salary with incentives tied to work RVUs, collections, procedures, quality metrics, or other measures. SullivanCotter reported that physician total cash compensation continued to rise in its 2025 survey, reflecting continuing supply-and-demand pressure in physician labor markets.
Federal Government Salary: VA Gastroenterologist
Federal gastroenterologists do not normally use the ordinary GS schedule for their clinical physician compensation. At the Department of Veterans Affairs, physicians are paid under Title 38, 38 U.S.C. §7431.
For 2026, VA places gastroenterology in Clinical Specialty Pay Table 2. A staff physician is Tier 1, with an annual range of $124,308 to $400,000. Supervisory or section-chief assignments are Tier 2, with a range of $200,000 to $400,000. Higher-level clinical leadership assignments are Tier 3, ranging from $225,000 to $400,000.
These are official annual pay ranges, not a promise that every VA gastroenterologist will earn the maximum. Actual compensation depends on factors such as qualifications, experience, assignment, recruitment considerations, and the applicable VA pay schedule.
Federal Government Salary Structure
| VA compensation level | 2026 annual range |
| Tier 1 — Staff Physician | $124,308–$400,000 |
| Tier 2 — Supervisor/Program Manager/Section Chief | $200,000–$400,000 |
| Tier 3 — Service Chief/Service Line Manager and specified higher assignments | $225,000–$400,000 |
The ordinary 2026 GS scale is therefore not the appropriate benchmark for a VA gastroenterologist. OPM’s 2026 GS tables do show a 1% General Schedule increase, but Title 38 physician pay is governed separately.
State/Local Government Salary
State and local governments do not have one national physician pay scale. A gastroenterologist employed by a state university, public hospital, county medical system, or other public employer may be paid under an academic faculty scale, a physician salary schedule, an employment contract, or a combination of those systems.
California’s University of California system provides a useful example. Its 2026-27 Health Sciences Compensation Plan publishes separate academic ranks and steps. On Scale 9, effective October 1, 2026, annual salaries range from $190,800 for an Instructor to $575,800 for Professor Step 9.
These UC figures are academic salary-scale examples, not a national gastroenterology average. A clinical gastroenterologist may have additional compensation under a campus-specific health sciences compensation plan.
State/Local Government Salary Structure California Example
| UC Health Sciences academic rank | 2026-27 annual salary |
| Instructor | $190,800 |
| Assistant Professor, Step 1 | $219,400 |
| Assistant Professor, Step 6 | $284,300 |
| Associate Professor, Step 5 | $341,300 |
| Professor, Step 1 | $316,600 |
| Professor, Step 9 | $575,800 |
The broader lesson is that state/local compensation must be researched employer by employer. Public university medicine can also include teaching, research, administrative duties, and separate clinical compensation.
Pay Variation by Location
Location can materially change both the advertised compensation and the financial value of that compensation.
For private-sector physicians, current salary estimates show meaningful differences between metropolitan markets. For example, Salary.com reported an average of $470,900 for gastroenterologists in San Diego in August 2026, compared with $455,200 in Philadelphia and $424,600 in Pittsburgh.
| Location | Reported average |
| San Diego, CA | $470,900 (Salary.com) |
| Philadelphia, PA | $455,200 (Salary.com) |
| Pittsburgh, PA | $424,600 (Salary.com) |
For federal VA positions, location-specific Title 38 schedules are maintained by VA, so candidates should check the current facility and applicable pay table rather than assuming a nationwide fixed salary.
Cost of living also matters. A $450,000 compensation package in a lower-cost market can provide substantially more purchasing power than the same nominal amount in a high-cost metropolitan area.
Salary Comparison
| Employment path | Representative 2026 compensation |
| Private-sector salary, 25th percentile | $410,400 |
| Private-sector salary, average | $436,600 |
| Private-sector salary, 90th percentile | $523,907 |
| Private physician compensation, gastroenterology average | $531,345 |
| VA staff gastroenterologist | $124,308–$400,000 official range |
| VA supervisory/section-chief | $200,000–$400,000 official range |
| UC California academic example | $190,800–$575,800 across Scale 9 ranks/steps |
The table should not be interpreted as an apples-to-apples ranking. The private figures include market estimates and physician compensation data, VA figures are statutory Title 38 ranges, and the UC figures represent an academic salary scale.
Career Progression and Advancement Path
Becoming a gastroenterologist requires substantial postgraduate training. BLS states that physicians generally complete a bachelor’s degree, medical degree, and specialty training; subspecialization can require an additional fellowship.
The gastroenterology fellowship itself must be 36 months under ACGME requirements. ABIM also lists 36 months as the minimum gastroenterology training requirement.
A typical pathway is:
College → Medical school → Internal medicine residency → Gastroenterology fellowship → Medical licensure → Gastroenterology practice
Within employment, progression can include:
- Early-career gastroenterologist: builds procedural volume and clinical experience.
- Experienced attending: may negotiate higher productivity incentives or take on specialized clinical responsibilities.
- Senior/partner physician: may receive partnership distributions or ownership-related income in qualifying practices.
- Academic physician: may progress from assistant professor to associate professor and professor.
- Government physician: may move into supervisory, section-chief, service-chief, or other leadership assignments.
Timelines after fellowship vary by employer and performance. They should not be treated as guaranteed promotion periods.
Benefits and Perks
Private-sector benefits depend heavily on the employer. Common offerings can include health insurance, retirement plans such as a 401(k), disability coverage, paid time off, malpractice coverage, and productivity incentives.
Federal VA employment has a more standardized benefits package. VA physician materials identify FERS retirement, the Thrift Savings Plan, Federal Employees Health Benefits, dental and vision insurance, life insurance, malpractice/liability protection, and potential education-debt assistance.
VA also advertises 26 paid vacation/personal days, 13 sick days annually, and 11 federal holidays for its physician workforce.
State and local benefits vary by employer. Public universities and hospitals may offer pension or retirement plans, health insurance, academic leave, research support, and other benefits, but candidates should review the specific employer’s benefits documents.
Deductions and Take-Home Considerations
A gastroenterologist’s gross salary is not the same as take-home pay. The final amount depends on filing status, deductions, retirement contributions, insurance premiums, and where the physician lives and works.
Federal Income Tax
Federal income tax is progressive. For 2026, the IRS maintains seven individual rates: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. For single taxpayers, the 37% bracket begins above $640,600 of taxable income; for married couples filing jointly, it begins above $768,700. The 2026 standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly.
A physician does not pay the top marginal rate on the entire salary. Different portions of taxable income fall into different brackets.
FICA
FICA includes Social Security and Medicare.
For 2026, the employee Social Security rate is 6.2% on wages up to the $184,500 Social Security wage base. Medicare is 1.45% on covered wages with no wage cap.
High-income physicians can also owe the 0.9% Additional Medicare Tax. The threshold is $200,000 for single filers and $250,000 for married couples filing jointly.
State Income Tax
State taxation can produce a major difference in take-home earnings. In 2026, nine states did not levy an individual income tax on wage or salary income: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming.
California is particularly relevant to physicians because it has graduated individual income-tax rates, with a top rate of 12.3%, plus an additional 1% tax on qualifying income above $1 million under California’s rules.
New York also has a progressive state income tax, and New York City has separate city income-tax rules.
Retirement Contributions
Private-sector gastroenterologists may contribute to a 401(k) or another employer-sponsored retirement plan. Government physicians may have access to FERS and TSP. Retirement contributions can reduce current taxable income when made through eligible pre-tax arrangements, although the exact treatment depends on the plan and contribution type. VA describes its retirement package as combining a federal pension, employer-matched TSP, and Social Security.
Because taxes and deductions vary so much, there is no responsible nationwide “take-home percentage” for this occupation.
How to Enter This Field / Get the Job
The basic qualification path is demanding but clearly defined.
- Complete an undergraduate degree.
- Complete medical school and earn an MD or DO.
- Complete internal medicine residency.
- Match into a three-year gastroenterology fellowship.
- Obtain the required state medical license.
- Complete required board-certification or eligibility requirements.
- Apply to hospitals, physician groups, academic centers, endoscopy practices, or government systems.
For federal VA employment, candidates should review the specific physician vacancy and its qualification requirements rather than assuming that the ordinary GS hiring process applies. VA physician positions use the agency’s physician hiring and Title 38 framework. VA directs physician candidates to its career and USAJOBS opportunities.
Which Sector Should You Choose?
If maximum earning potential is the priority, private-sector gastroenterology generally provides more opportunity for productivity incentives, partnership income, and other compensation beyond a guaranteed salary. Federal VA employment can be attractive for physicians who value predictable benefits, pension eligibility, malpractice protection, and a more standardized compensation structure. State and academic systems sit between these models and can be especially attractive for physicians who want teaching, research, or public-service work. The trade-off is that higher private-sector compensation may come with heavier productivity expectations, call responsibilities, or greater variation in benefits and job security.
FAQs
Is gastroenterology a high-paying medical specialty?
Yes. Doximity’s 2026 report places gastroenterology at $531,345 in average physician compensation, making it one of the higher-paid medical specialties.
Is the VA salary lower than private practice?
It can be, particularly when comparing a VA salary with a high-producing private-practice gastroenterologist. However, salary alone does not capture the VA’s pension, TSP, health benefits, malpractice protection, leave, and other benefits.
Does a gastroenterologist need a fellowship?
Yes. Gastroenterology is an internal-medicine subspecialty, and ACGME requires a 36-month gastroenterology fellowship program.
Where do gastroenterologists tend to earn the most?
Compensation varies by practice model and market. High compensation can be available in private practices, procedure-heavy environments, partnership models, and areas where physician supply is limited. Location alone does not determine pay.
Does location affect the value of a high salary?
Yes. Housing, insurance, state income tax, local tax, commuting costs, and other living expenses can materially change the purchasing power of the same gross salary.
How much of the advertised salary reaches the physician’s bank account?
There is no universal answer. Federal income tax, FICA, state and sometimes local income tax, health-insurance premiums, and retirement contributions all reduce gross earnings. High-income physicians also need to account for the Additional Medicare Tax.
Conclusion
Gastroenterology remains a high-compensation medical specialty in the United States, but the actual financial outcome depends heavily on practice model, productivity, geography, and benefits.
Private practice can offer the highest upside, while VA and public academic employers can offset lower or more standardized salary structures with strong benefits, retirement programs, and career stability.
