Frequently Asked Questions
Quick answers about using CureAdvantage’s free medical billing tools.
Are these medical billing tools really free to use?
Yes. Every tool on this page is 100% free with no login, no credit card, and no usage limits. CureAdvantage builds these tools to help billing teams and physicians work faster, and they’ll stay free.
How current is the code data (ICD-10, CPT, CDT, denial codes)?
ICD-10-CM data is pulled from the live CMS.gov database and reflects the current annual code set. CDT dental codes follow the current edition, and denial code guidance is reviewed and updated as CMS and payer policies change.
Do I need to create an account or enter patient information?
No account is required for any tool. None of the calculators or lookups ask for patient-identifiable information — you’re only working with codes, payer names, and practice-level numbers.
How accurate is the AI-generated billing guidance?
The Smart Billing Assistant and similar AI-powered tools are meant to speed up research and flag common issues, not replace your billing team’s judgment or your payer’s official policy. Always confirm high-stakes decisions against the payer’s current guidelines.
Which tool should I start with?
If you’re chasing denials, start with the Denial Code Lookup or PayerGrade. If you’re trying to stop revenue loss before it happens, the Revenue Leakage Calculator and Claim Filing Deadline Checker are the best first stops.
