FAQ
How does Lime Shield ensure my medical bill privacy?
Lime Shield is designed for maximum privacy. Your medical bills are analyzed entirely on your device using Apple's built-in text recognition. Nothing is uploaded to any server, and no account is required, meaning your sensitive information never leaves your phone.
What types of billing errors does Lime Shield check for?
Lime Shield checks for a wide range of issues, including arithmetic errors, duplicate charges, prices significantly above typical rates, vague lump sums, and charges for services already included in a panel. It also identifies potential issues with after-hours fees, missed appointment fees, and facility fees.
Does Lime Shield cost money to use?
The free version of Lime Shield offers full analysis of your medical bills. A Pro subscription is available for unlimited scans and unlimited dispute letters, offering enhanced convenience for frequent users.
Can Lime Shield help me dispute a bill?
Yes, Lime Shield provides exact wording for questions to ask billing departments and suggests responses to common replies. It can also write a full review letter for you, listing each flagged charge, ready to be emailed or printed.
What happens if my bill is just a summary?
If your bill is a summary, Lime Shield can generate a request for an itemized bill. This is crucial because many billing errors are only visible once you receive the detailed version of your bill.
