We come to you
A licensed clinician arrives at your location, reviews your consent and health updates with you, and provides your care.
Healing Soulutions provides care in New York City, with most visits in Manhattan. Contact us to confirm availability at your location.
Licensed nurses and a board-certified nurse practitioner — trained in critical care, ICU and emergency medicine, with a special focus in functional medicine and integrative health.
Yes. Virtual consultations with a provider are available where clinically appropriate, for clients located in states where our clinicians are licensed (currently New York). Some concerns require an in-person visit, and telehealth is never a substitute for emergency care.
Healing Soulutions is an out-of-network, private-pay provider; payment is due at the time of service by major card through a secure, PCI-compliant processor, and we do not bill insurance. On request, we provide a superbill for your own FSA/HSA (or insurer) reimbursement, and we make no representation that any amount will be reimbursed. For lab work, share your insurance card when you book; Labcorp bills your insurance directly for the lab processing. Any deductible, copay, or test your plan doesn't cover is billed to you by Labcorp. As required by the No Surprises Act, you receive a Good Faith Estimate of expected charges before your scheduled visit.
Choose your services, share a brief health history, review the financial agreement, secure your visit with a card on file, and pick a date and time. We confirm within 24 hours. Treatment consent and our privacy acknowledgment are signed in your patient portal or on your booking form, before care begins.
Reschedule free with 12+ hours' notice; inside 12 hours a $100 fee applies. Cancellations within 24 hours incur a $125 fee. No-shows after a 30-minute grace period may incur up to $175. Full details are in the Financial Agreement presented during booking.
