How to Check a Doctor's Credentials and Disciplinary History#

Choosing a doctor is one of the most consequential decisions you make for your health, yet most patients never verify whether their provider is properly licensed, board certified, or has a history of disciplinary actions. Every year, patients discover too late that their doctor had a suspended license in another state or multiple malpractice settlements.

The good news is that all of this information is publicly available. Here is a step-by-step guide to checking a doctor's credentials using free online tools, what each verification tells you, and what red flags to watch for.

Step 1: Verify the Medical License#

Every practicing physician must hold an active medical license in the state where they treat patients. This is the most basic check and takes about two minutes.

Where to check: Your state medical board website. Every state has one.

How to find it: Search "[your state] medical board license lookup" or visit the Federation of State Medical Boards (FSMB) at docinfo.org, which aggregates license data from all 50 states plus D.C. and U.S. territories.

What to look for:

• License status. It should say "Active" or "Current." Any other status (Expired, Suspended, Revoked, Probationary, Restricted) is a red flag.
• License type. MD (Doctor of Medicine) or DO (Doctor of Osteopathic Medicine) for physicians. Make sure it matches what the doctor claims.
• Issue and expiration dates. Licenses must be renewed every 1-3 years depending on the state. An expired license means the doctor cannot legally practice.
• Multiple states. If your doctor practices in more than one state, verify the license in each one. A doctor can have an active license in one state and a revoked license in another.

The FSMB's DocInfo tool shows disciplinary actions across all states in a single search. This is the fastest way to check for multi-state issues.

Step 2: Confirm Board Certification#

Board certification means the doctor passed rigorous exams in their specialty after completing residency. It is voluntary -- a doctor can legally practice without it -- but it signals a higher standard of training and ongoing education.

Where to check: The American Board of Medical Specialties (ABMS) at certificationmatters.org.

What to look for:

• Certification status. "Certified" means active and current. "Not Certified" means the doctor either never achieved certification or let it lapse.
• Specialty and subspecialty. Verify that the doctor's certification matches what they are treating you for. A board-certified internist performing cosmetic surgery is practicing outside their certified specialty.
• Certification date. Board certification must be renewed every 6-10 years depending on the specialty. Older certifications may have been lifetime (pre-1990), which is still valid but means no recertification exams were required.

What About Osteopathic Board Certification?#

DOs (Doctors of Osteopathic Medicine) may be certified through either the ABMS or the American Osteopathic Association (AOA). Check both if your doctor is a DO. The AOA verification tool is at osteopathic.org.

Does Board Certification Matter?#

Research consistently shows that board-certified physicians have better patient outcomes on average. A 2024 study in JAMA found that board-certified surgeons had 12% fewer complications than non-certified surgeons performing the same procedures. It is not a guarantee of quality, but it is a meaningful signal.

Step 3: Look Up the NPI Number#

Every healthcare provider in the United States has a National Provider Identifier (NPI) -- a unique 10-digit number assigned by CMS. Looking up a doctor's NPI confirms their identity and practice details.

Where to check: The NPI Registry at npiregistry.cms.hhs.gov.

What it tells you:

• Full legal name and credentials. Matches the provider's claimed identity.
• Taxonomy code. This is the provider's specialty classification. A taxonomy code of 207Q00000X means Family Medicine. If the code does not match the doctor's claimed specialty, investigate further.
• Practice address. Confirms where the doctor is currently practicing.
• Authorized official. For group practices, shows who manages the NPI enrollment.

The NPI lookup is especially useful when you are referred to a specialist and want to confirm they are who they say they are before your appointment.

Step 4: Check Disciplinary Actions#

Disciplinary actions include formal reprimands, license restrictions, suspensions, revocations, and consent orders. These are public record in every state.

Where to check:

• State medical board website. Search for the doctor by name. Disciplinary records are usually under "Enforcement Actions," "Board Orders," or "Public Documents."
• FSMB DocInfo (docinfo.org). Shows actions from all states in one search. Requires a small fee ($9.95 per search as of 2026).
• NPDB (limited access). The National Practitioner Data Bank contains malpractice payments and adverse actions, but it is not directly accessible to the public. However, hospitals and health plans query it, and some data surfaces through state board records.

What disciplinary actions mean:

| Action | Severity | What It Means | |---|---|---| | Letter of Reprimand | Low | Formal warning, no restrictions on practice | | Fine | Low-Medium | Monetary penalty, often for administrative violations | | Probation | Medium | Doctor can practice with conditions (monitoring, education) | | Restriction | Medium-High | Limitations on scope (cannot prescribe certain drugs, cannot perform surgery) | | Suspension | High | Cannot practice for a defined period | | Revocation | Highest | License permanently removed | | Voluntary Surrender | High | Doctor gave up license, often to avoid a formal hearing |

A single letter of reprimand for a minor administrative issue (late CME credits, for example) is not necessarily concerning. Multiple actions, probation, or any suspension should give you serious pause.

Step 5: Research Malpractice History#

Malpractice claims are more complex to interpret than disciplinary actions. A malpractice payment does not automatically mean a doctor is bad -- some specialties (obstetrics, surgery, emergency medicine) face higher claim rates regardless of quality.

Where to check:

• State medical board. Some states (California, Massachusetts, New York, Florida, and others) require doctors to report malpractice payments and make them publicly searchable.
• Court records. County court websites often have searchable databases of civil lawsuits. Search the doctor's name to find filed cases.
• State health department websites. Some states publish malpractice data through their department of health rather than the medical board.

How to interpret malpractice data:

• One or two claims over a long career is not unusual, especially in high-risk specialties. An obstetrician with one claim in 20 years of practice is within normal range.
• Three or more claims starts to stand out. Look at whether the claims involve similar issues (repeated pattern) or are unrelated.
• Large settlements ($1 million+) suggest serious harm occurred. Read the details if available.
• Claims in the last 5 years are more relevant than claims from 15-20 years ago.

Step 6: Check Hospital Affiliations#

Hospital privileges mean a hospital has independently verified the doctor's credentials, training, malpractice history, and clinical competence through a process called credentialing. This is one of the most thorough vetting processes in medicine.

Where to check: Call the hospital's medical staff office and ask whether the doctor has active privileges. You can also check the hospital's online physician directory.

Why it matters: If a doctor has no hospital affiliations, it could mean they only practice in outpatient settings (not necessarily a concern), or it could mean hospitals have declined to grant them privileges (a red flag). Ask the doctor directly if you have questions.

Step 7: Read Reviews With Context#

Online reviews provide a patient perspective that credentials alone cannot capture. But they require careful interpretation.

Where to look:

• Google Reviews. Largest volume, covers most providers.
• Healthgrades. Healthcare-specific, includes patient satisfaction scores.
• Vitals. Includes wait times and bedside manner ratings.
• Zocdoc. Verified patient reviews (only from patients who booked through Zocdoc).
• Our directory. We aggregate reviews and transparency scores for providers in our network.

How to read reviews effectively:

• Ignore the extremes (one-star rants and five-star raves). Focus on the three- and four-star reviews for the most honest signal.
• Look for patterns. One complaint about wait times is noise. Twenty complaints about wait times is a real issue.
• Separate clinical complaints from administrative ones. "The billing department is terrible" is a different problem than "the doctor missed my diagnosis."
• Check the dates. Recent reviews matter more than reviews from five years ago.

Quick-Reference Checklist#

Use this checklist before choosing a new doctor:

• [ ] License active and in good standing (state medical board or docinfo.org)
• [ ] Board certified in their claimed specialty (certificationmatters.org)
• [ ] NPI number matches their name and specialty (npiregistry.cms.hhs.gov)
• [ ] No serious disciplinary actions (state board + FSMB)
• [ ] Malpractice history reviewed if available (state-specific)
• [ ] Hospital privileges confirmed (for surgeons and specialists)
• [ ] Online reviews checked for consistent patterns

The entire process takes 15-20 minutes and is completely free (except the optional FSMB DocInfo report). That small investment can save you from a provider who should not be practicing.

FAQ#

Can a doctor practice with a malpractice claim on their record?#

Yes. A malpractice claim or settlement does not affect a doctor's license. Only the state medical board can restrict or revoke a license. Malpractice is a civil matter between the patient and the doctor's insurance company. Many excellent doctors have malpractice claims, especially in high-risk specialties.

What if my doctor is not board certified?#

A doctor without board certification can still be a competent provider. Board certification is voluntary. However, it signals that the doctor has passed specialty exams and maintains continuing education. If your doctor is not board certified, ask about their training, experience, and why they chose not to pursue certification.

How do I report a doctor for misconduct?#

File a complaint with your state medical board. Every state board has an online complaint form. You can also report to your insurance company, the hospital where the doctor has privileges, and the relevant specialty board. Complaints trigger an investigation -- you do not need proof, just a factual description of what happened.

Are credentials different for nurse practitioners and physician assistants?#

Yes. Nurse practitioners (NPs) are certified through nursing boards (AANP or ANCC) and licensed by state nursing boards, not medical boards. Physician assistants (PAs) are certified through NCCPA and licensed by medical or PA-specific boards depending on the state. Use the relevant board's lookup tool to verify their credentials.
