Houston, TX

Houston has active licensed clinicians across every major specialty. The exact count varies week to week as new clinicians get NPIs and others retire or relocate — the number you see on this page is refreshed directly from the federal NPPES NPI Registry so it stays current. Browse by specialty above to see how many providers are indexed in each category.

Every listing on the Houston directory shows the practice street address and neighborhood, so you can sort by proximity to your home, office, or Austin. For urgent same-day needs, use the specialty filters (urgent care, family medicine, internal medicine) at the top of the page — those categories index the Houston clinicians most likely to have next-day availability.

Open any specialty page under the Houston directory (for example, Oncology and Cardiology) and use the Insurance filter to narrow the list to your carrier. Coverage varies by plan tier — a doctor may accept Blue Cross Blue Shield PPO but not the HMO product — so always confirm your specific plan with the office before booking. Texas Medicaid and Medicare Advantage networks also vary practice-by-practice in Houston.

In Houston, patients most often search for Oncology, Cardiology, Orthopedic Surgery, Pain Management, along with primary-care family medicine and internal medicine. Every specialty listed on this page links to a dedicated Houston specialty hub with clinician profiles, sub-specialty filters, and patient guides.

Yes — most primary-care practices in Houston and many specialists (especially behavioral health, dermatology, endocrinology, and follow-up cardiology) now offer video visits. Look for the virtual-care badge on a clinician's profile, or ask the office when you book. State licensure rules apply, so the clinician must be licensed in Texas to see you if you're physically located in the state at the time of the visit.

Houston is served by a mix of academic medical centers, community hospitals, and regional health systems. The specific systems vary by neighborhood — check a clinician's profile for hospital affiliation and admitting privileges, which matter most for surgical or inpatient care. For routine outpatient visits, hospital affiliation is less important than board certification and office location.

For same-day care in Houston, filter the directory by Urgent Care, Family Medicine, or Internal Medicine and call the closest offices first — most reserve a handful of slots each day for acute visits. Retail clinics and hospital-affiliated express care sites in Houston typically accept walk-ins for minor illnesses, prescription refills, and travel medicine.

Medicare acceptance is common across Houston primary-care and specialty practices; Medicaid participation is narrower and depends on the managed-care plan you carry in Texas. Filter the Houston directory by insurance, or call the office and confirm both the payer and the specific plan (for example, Medicare Advantage vs Original Medicare) before scheduling.

Many Houston practices have Spanish-speaking clinicians or in-office interpreter services. Ask the front desk when you call, or search the directory for practices that publish "Se habla español" on their profile. Larger Houston hospital systems typically provide phone-based interpreter services in 200+ languages at no cost to the patient.

Yes — if wait times in Houston are long, patients often find faster availability in Austin, Dallas, El Paso. Use the state hub for Texas to browse other metros, or open a specialty page and change the location filter. Board certification and training are what matter for quality; a 20–40 minute drive can meaningfully shorten your wait for high-demand specialties.

Use the Ask a Doctor (AI) tool to describe your symptoms in plain language — it maps your description to the most likely specialty (for example, headaches with visual changes might route to neurology or ophthalmology) and then hands you a filtered list of Houston clinicians in that category. It's a discovery tool, not a substitute for medical advice; for anything urgent, call 911 or go to your nearest Houston ER.
