Because conventional insurance models limit extended consultation times and advanced functional lab testing, FunctionALL Health operates on a fee-for-service model. However, many patients with PPO insurance plans successfully receive out-of-network reimbursement through superbills.
What is a Superbill?
A superbill is an itemized medical receipt containing all standardized CPT procedure codes, ICD-10 diagnostic codes, practitioner NPI/Tax ID numbers, and visit fees required by insurance carriers.
How to Submit a Superbill in 4 Easy Steps
1. Request Your Superbill: Contact our office or request your superbill through the Self Request Portal following your consultation.
2. Contact Your Insurer: Call the member services number on the back of your insurance card and inquire about 'out-of-network primary/specialist care reimbursement'.
3. Submit via Portal or App: Upload your superbill directly to your insurance company's online member portal or mobile app.
4. Receive Reimbursement or Deductible Credit: Depending on your plan, reimbursement checks or deductible credits are applied directly by your insurer.
