Because most insurance companies do not cover the full scope of his practice, Dr. Wu does not participate in commercial insurance plans or with Medicare/Medicaid. Direct-pay physicians like Dr. Wu who are outside the insurance system and its bureaucracy are able to spend more time with each patient, and focus squarely on the doctor-patient relationship without the intrusion of a third-party. 

However, many private insurances come with out-of-network benefits, allowing the patient to submit a bill for covered services to be reimbursed. Dr. Wu may bill for medical consultations and procedures and be able to provide an itemized bill to assist those who wish to submit a claim. For those with a Health Savings Account (HSA), the medical services rendered would qualify as an eligible expense. Dr. Wu's services are a potentially cost-effective alternative to high copay/high deductible office visits.
