Frequently asked questions
If you have anything else you want to ask, reach out to us.
Is Oopda free?
Yes. Oopda is completely free to use—we built it to help people take control of their medical bills, not to add another expense. If we ever add premium features down the road, the core tools (scanning, verification, and advocacy templates) will stay free.
What is a CPT code and why do I need to know it?
CPT (Current Procedural Terminology) codes are 5-digit codes that describe every medical service or procedure. Knowing the CPT code for each charge allows you to verify you actually received that service, look up typical costs, compare to your insurance EOB, and catch duplicate charges. Oopda teaches you what CPT codes mean and helps you request them from providers.
How common are medical billing errors?
Medical billing errors are common—some industry analyses estimate that up to 80% of itemized bills contain at least one mistake. Common errors include duplicate charges, charging for services not provided, upcoding (billing for more expensive services), and incorrect patient responsibility calculations. These errors can cost patients hundreds or thousands of dollars—which is why verification is so important.
How does the document scanning work?
Oopda uses advanced AI to read your medical bills automatically. Simply photograph your bill with your phone's camera, and our AI extracts key information like provider name, dates, amounts, patient name, and account numbers. The data appears in your app within minutes, and the original document is stored securely for your records.
Can I request an itemized bill from any provider?
Yes! Under federal law, you have the right to request detailed billing information from any healthcare provider. An itemized bill shows every service provided with CPT codes, dates, and charges. Oopda provides an email template to request itemized bills professionally and effectively.
Is my medical information secure?
Yes. Oopda uses bank-level security with encrypted storage, AWS Cognito authentication, and secure cloud infrastructure. All documents and data are encrypted both at rest and in transit. We never sell your data to third parties, and your bills are only visible to you.
Can I manage bills for my whole family?
Yes! Oopda automatically detects family members from the patient names on your bills and organizes everything in one place. You can view all bills across all family members, filter by person, and track payment history for each individual.
How does Oopda help me dispute incorrect charges?
Oopda provides professional email templates to dispute billing errors. The templates state your concern clearly, reference specific bill details, cite your patient rights, and request corrective action. Simply customize the template with your information and send it to your provider. Oopda stores a copy for your records.
What if the AI extracts something incorrectly?
While our AI is highly accurate, you can use the "Report Issue" feature if you notice incorrect data. Our team reviews reports and corrects the data, while using your feedback to improve the system. This ensures data integrity and helps make Oopda better for everyone.
Does Oopda give medical or legal advice?
No. Oopda helps you organize, understand, and verify your medical bills, but it doesn't provide medical, legal, or financial advice. For specific concerns, consult a qualified professional.
