Cold sores
Feel the tingle coming? A clinician reviews your history the same day and plans treatment for this outbreak, or prevention for the next.
Painful mouth ulcers making it hard to eat? Share a photo and a Texas clinician reviews your sores and plans relief.
Yes, for adults 18 and older in Texas. Painful mouth ulcers making it hard to eat? Share a photo and a Texas clinician reviews your sores and plans relief. Review is by a Texas-licensed Passion Health clinician, 24/7 on weekdays and 7 AM–9 PM CT on weekends. The flat price is $59, or use insurance. A prescription goes to the pharmacy you choose only if it's appropriate; controlled medicines are never prescribed online. If you have a sore, white or red patch, or lump in your mouth that hasn't healed after 2 weeks, you need an in-person visit within a few days instead, and you don't pay the online fee.

A canker sore (aphthous ulcer) is a small, painful, round sore inside the mouth with a white or yellow center and a red border. Canker sores are not contagious and are different from cold sores. Triggers include minor mouth injuries, stress, certain foods and some toothpastes. Frequent sores can be linked to low iron, B12 or folate, or other conditions.
Not near one of our clinics? Online Care is open to adults anywhere in Texas; our clinics are in Dallas–Fort Worth. If the safety questions or your clinician show you need to be examined, we tell you what kind of care you need and how soon — an emergency room, an urgent care center, or a clinician near you. If you've already paid, the full fee is refunded and you get a written summary of your visit to take with you.
Also call 911 for chest pain, trouble breathing, stroke signs, a sudden severe headache, fainting, a seizure, severe bleeding, new confusion, throat swelling, an overdose or thoughts of harming someone else — and call or text 988 for thoughts of harming yourself. If screening routes you before you pay, nothing is charged. If a clinician routes you after you've paid, the full fee is refunded.
About 5 minutes, with photos if they help. Emergency and safety questions come first.
A Texas-licensed Passion Health clinician reads everything and calls or videos you if they need more.
If treatment is appropriate, a prescription goes to the pharmacy you choose.
A 48-hour check-in and secure messaging. If you need to be seen, a same-day visit at our Dallas–Fort Worth clinics, or clear advice on where to go near you.
Shown so you know what to expect. The reviewing clinician decides what, if anything, is appropriate for you — a prescription is never guaranteed, and controlled medicines are never prescribed online.
Using insurance: we're in network with BCBS of Texas, Aetna, UnitedHealthcare, Cigna, Humana and Healthcare Highways, and we verify eligibility for every plan before review — you see your estimated cost-share first. New patients have a short video visit, because plans pay for a visit, not a form. Same-day review applies to self-pay visits; insurance visits begin once we've verified your plan, which is the next business morning if you submit overnight or on a weekend. Medicare, Medicaid, CHIP and TRICARE are billed to the program, and the cash rate isn't offered for covered services.
Full refund if your case isn't accepted: if the clinician doesn't accept your case for online care, for any reason, the full fee is refunded to your card within 10 business days, and we help you get the care you need: a same-day visit at one of our Dallas–Fort Worth clinics or, if you're not near one, clear advice on where to be seen and a written summary of your visit. With insurance, no claim is submitted for the online review. Paying the flat price yourself? You can ask for a written Good Faith Estimate before your visit.
Labs and imaging, if needed, are billed separately, and medication is paid at your pharmacy. Passion Health doesn't sell, ship or mark up medication.
A 48-hour check-in message and 14 days of secure messaging. If you're not improving, we book a same-day clinic visit, or, if you're not near one of our clinics, tell you where to be seen near you.
The flat cash rate is $59 for a quick evaluation, or use your insurance and pay your plan's cost-share — we show you an estimate before review starts. Medication is paid at your pharmacy. If the clinician doesn't accept your case for online care, for any reason, the full fee is refunded to your card.
A Texas-licensed Passion Health clinician reviews every intake and decides your plan — not software. For canker sores, Texas law lets the clinician evaluate you from a condition-specific intake plus your photos and records, and they'll call or video you whenever something needs a conversation. New patients using insurance have a short video visit, because plans pay for a visit, not a form.
No. You're paying for a licensed clinician's evaluation and plan. Many visits end with a prescription; some end with a different plan, a test, or a referral. Controlled medicines — stimulants, benzodiazepines, opioids, testosterone, sleep aids like zolpidem — are never prescribed at an online visit.
Canker sores form inside the mouth, on the inner cheeks or lips, tongue or gums, and aren't contagious. Cold sores are caused by a herpes virus, usually appear as clusters of blisters on or around the outer lips, and can spread to others. Treatment differs, so tell your clinician exactly where the sore is and share a photo if you can.
Most minor canker sores heal on their own in 1 to 2 weeks, and the pain usually eases after the first few days. Larger sores can take several weeks and may leave a scar. A sore, patch or lump that hasn't healed in 2 weeks should be checked in person, because other conditions, including mouth cancer, can look similar.
A clinician may form a valid patient relationship online using store-and-forward technology — your condition-specific intake, photos and records — paired with a call or video when needed, as long as the in-person standard of care is met (Tex. Occ. Code §111.005(a)(3), §111.007). Your clinician gives you guidance on follow-up care and, with your consent, sends new patients' visit notes to their primary care physician within 72 hours (§111.005(b)).
