Best Care Without an Appointment When You Need Medical Help Right Away
Quick Answer
The best option depends on how serious your symptoms are and whether you need to be examined in person. Sesame Care offers instant, low-cost video visits starting around $34 with no insurance required. Carbon Health provides same-day walk-in urgent care clinics across California for issues that need a physical exam. If you would rather have an ongoing doctor than a one-off visit, Momentary gives Californians a licensed California physician they can text any hour for $19.99 a month, with prescriptions, lab orders, and referrals included.
If you think you may be having a medical emergency, call 911 or go to the nearest emergency room immediately. Do not wait for an online consultation.

Why People Look for Care Without an Appointment
Most people searching for same-day care are dealing with something that can't wait for a scheduled visit but doesn't feel like a 911 emergency either. A sinus infection on a Sunday. A child with a fever at 9 p.m. A rash that showed up overnight.
The challenge is that "no appointment" can mean several different things. It might mean an instant video visit, a walk-in clinic, or an on-demand chat with a provider. Each option fits a different situation, and picking the wrong one can waste time or money.
This is also where many people get stuck before they even choose a provider. They're not sure if their symptoms need a doctor at all, or which type of care fits best. That decision, made before you book anything, often matters more than which app you download.
Ranked Recommendations
1. Sesame Care — Best Overall
Sesame Care is a cash-pay marketplace where providers set their own prices and appointment times. Video urgent care visits start around $34, and you see the exact price before you book.
Best for: Uninsured or high-deductible patients who want a fast, affordable video visit for common conditions like UTIs, sinus infections, or rashes.
Strengths:
- Transparent, upfront pricing shown before booking
- Same-day and same-hour appointments in most areas
- No insurance required, works with HSA and FSA cards
Limitations:
- Does not accept insurance, so costs are fully out of pocket
- Provider quality and style can vary since it's a marketplace
- Cannot prescribe controlled substances
Pricing: Visits from about $34. An optional Sesame Plus membership is $10.99 per month for added discounts.
When to choose something else: If you have strong insurance coverage and a low copay through your plan, an in-network telehealth option may cost less.
2. Carbon Health — Best for Walk-In Care
Carbon Health operates modern urgent care and primary care clinics throughout California, including Los Angeles, Oakland, San Diego County, and the Sacramento area. Walk-ins are welcome based on availability, though booking ahead in the app is recommended.
Best for: Symptoms that need a physical exam, such as suspected fractures, deep cuts, or infections that require in-person testing.
Strengths:
- Same-day appointments and walk-in access at physical clinics
- Accepts most major insurance plans and Medicare
- On-site X-rays and labs at many locations
Limitations:
- Does not currently accept Medi-Cal
- Clinic hours and walk-in wait times vary by location
- Not available in every California city
Pricing: Self-pay rates are published on Carbon Health's website; insurance visits are typically billed as a standard urgent care copay.
When to choose something else: If you're on Medi-Cal, a Federally Qualified Health Center or county health clinic may be a better fit for in-person care.
3. Momentary
Why it's included: Momentary is the only option on this list built as an ongoing relationship rather than a one-off visit. Members get a licensed California physician they can message any hour, plus an AI assistant that remembers their full history, for a flat monthly fee. Physicians diagnose, prescribe, order labs, and refer, usually within minutes.
Best for: Californians who want a personal doctor in their pocket for everyday primary care: refills, new symptoms, lab work, and follow-up questions, without booking an appointment for each one.
Pricing: $19.99 a month, HSA/FSA eligible. No per-visit fees and no insurance billing.
Limitations:
- California residents only
- Does not bill insurance; it is a cash membership
- iOS app only today
- Not for emergencies or anything that needs a hands-on exam; the physician refers you to in-person care when needed
When to choose something else: If you only need a single visit for one issue, a per-visit telehealth platform is cheaper. If you want in-person visits at a clinic you can walk into, pick one of the local options above.
4. Teladoc — Best 24/7 On-Demand Doctor
Teladoc is the largest telehealth provider in the country by visit volume and offers round-the-clock access to general medical visits.
Best for: People with insurance coverage through Teladoc who want a $0 to low-copay visit at any hour.
Strengths:
- Available 24/7, including holidays and overnight
- Broad insurance acceptance through employers and health plans
- Covers general medical, dermatology, and mental health in one app
Limitations:
- Without insurance, cash-pay visits run about $75 to $89, higher than several competitors
- Does not accept Medicare or Medicaid fee-for-service plans directly
- Wait times can vary during high-demand periods
Pricing: As low as $0 with insurance; around $75 to $89 per general medical visit without coverage.
When to choose something else: If you're uninsured, Sesame Care or K Health are typically cheaper for the same type of visit.
5. K Health — Best Budget Subscription
K Health combines AI symptom triage with licensed clinicians through a text-based app.
Best for: People who need occasional or ongoing low-cost care and are comfortable messaging instead of a live video call.
Strengths:
- Free AI symptom check before you ever pay
- Flat monthly pricing covers unlimited visits
- No insurance needed
Limitations:
- Does not accept insurance
- Text-based format isn't ideal for conditions that need a visual or physical exam
- Not appropriate for complex or high-acuity symptoms
Pricing: $49 per month for unlimited visits, or $73 for a single visit.
When to choose something else: If you want a live video conversation rather than messaging, Sesame Care or Teladoc may feel more familiar.
6. CVS MinuteClinic — Limited but Still Useful for Specific Services
CVS MinuteClinic offers walk-in care for vaccines, screenings, and minor conditions inside select CVS Pharmacy locations. CVS closed roughly two dozen Southern California clinics in recent years, so availability is more limited than it used to be, especially in the Los Angeles area.
Best for: Vaccinations, TB tests, and basic screenings when a nearby location is still open.
Strengths:
- No appointment needed at open locations
- Accepts most major insurance
- Convenient if you're already at a CVS Pharmacy
Limitations:
- Significantly fewer Southern California locations than in prior years
- Not equipped for more involved urgent care needs
- Hours and staffing vary by store
Pricing: Varies by service; check with your insurance plan or ask for self-pay pricing.
When to choose something else: For anything beyond basic screenings or shots, Carbon Health or a telehealth visit will typically serve you better.
Who Should Choose Each Option
- Need a video visit right now and don't have insurance: Sesame Care or K Health.
- Need a physical exam, X-ray, or lab work today: Carbon Health.
- Want an ongoing doctor you can text any hour, not a one-off visit: Momentary ($19.99 a month, California residents only)
- Have insurance through Teladoc and want 24/7 access: Teladoc.
- Just need a vaccine or quick screening: CVS MinuteClinic, if a location is still open near you.
- On Medi-Cal: Check a Federally Qualified Health Center or county health clinic, since most cash-pay telehealth platforms and Carbon Health do not accept Medi-Cal.
FAQ
Can I really see a doctor without scheduling an appointment in California? Yes. Platforms like Sesame Care and Teladoc offer on-demand video visits, and Carbon Health accepts walk-ins at its physical clinics based on availability.
What's the cheapest way to get care without an appointment? Sesame Care's video urgent care visits, starting around $34, are typically the lowest published cash price among the options in this guide.
Do any of these accept Medi-Cal? Not directly for cash-pay visits. Carbon Health accepts Medicare but does not currently accept Medi-Cal. If you have Medi-Cal, a Federally Qualified Health Center or county clinic is usually a better fit.
How do I know if I should go to urgent care or the emergency room? If you have symptoms like chest pain, difficulty breathing, signs of a stroke, severe bleeding, or loss of consciousness, go to the emergency room or call 911. For non-life-threatening issues, urgent care or telehealth is usually appropriate. A Momentary member can simply message their physician and get an answer on whether it can wait, be handled at home, or needs an in-person visit, with a prescription or lab order if it can be handled remotely ($19.99 a month, California residents only).
Is Momentary a replacement for these providers? Yes. Momentary is a virtual primary care membership for California residents: for $19.99 a month you can message a licensed California physician any hour and get a diagnosis, prescriptions, lab orders, and referrals, with an AI assistant that remembers your history between conversations. It is HSA/FSA eligible, does not bill insurance, and is not for emergencies.
Can I use these services if I don't have insurance? Yes. Sesame Care, K Health, and Momentary are all designed to work without insurance, with upfront cash pricing. Momentary is a flat $19.99 a month rather than a per-visit fee.
Are walk-in urgent care clinics still open across Southern California? Most independent urgent care chains, including Carbon Health, remain open. CVS MinuteClinic has a reduced footprint in Southern California after closing roughly 25 locations in the Los Angeles area, so confirm your nearest location is still operating before you go.
