Frequently Asked Questions

How does the free plan work?

The free tier is free forever — daily usage limits, no credit card. New individual accounts also get one 30-day free trial, with the features shown when it starts; when it ends you can choose a plan or keep using the free tier.

What HCC models are supported?

ICD-10 Coding Pro includes all 9 risk-adjustment models: CMS-HCC V22/V24/V28, CMS-HCC ESRD V21/V24, RxHCC V05/V08, and HHS-HCC V07/V08 (which versions apply depends on the payment year). Each code shows its HCC category, RAF weight, and hierarchy relationships.

How does the AI coding guidance work?

The AI analyzes your coding context and surfaces relevant ICD-10-CM guidelines, coding considerations, and potential specificity improvements. It's grounded in official CMS data; review its suggestions before you code. Available on Individual Pro AI, Corporate Basic AI, and Corporate Pro AI plans.

Can I use this with patient records (PHI)?

Individual ICD-10 Coding Pro accounts are a self-serve coding reference — do not enter patient identifiers or PHI. Organization accounts may process PHI only under a signed Business Associate Agreement, in the features it covers.

How current is the data?

The database uses official CMS ICD-10-CM data and is updated every fiscal year. You can switch between fiscal years (FY2024 through FY2027) for retrospective reviews and audits.
