For Professionals — Project Kos
For Professionals

You already know the system.
This is for navigating it alongside everyone else.

Project Kos is a free, independent reference built on CMS and federal Medicare statute. Nothing is sold here. No referral arrangements, no sponsored content, no conflicts of interest. Use it to explain the system to patients and families — or to look something up yourself.

What brings you here?
Clinical & care coordination
You work with patients through transitions
Discharge planners, case managers, social workers, home health clinicians — you need plain-language resources to share with patients and families, and a reference for coverage and documentation questions.

A note on independence

Project Kos has no referral arrangements, no preferred provider relationships, and no sponsored content. No organization has paid to appear in the directory or anywhere else on this site. Coverage information is sourced directly from the CMS Medicare Coverage Database, Medicare Benefit Policy Manuals, and applicable sections of the Social Security Act. If you identify an inaccuracy, please report it — we commit to reviewing and correcting confirmed errors within 3 business days.

Built for the people inside the system.

Free to use, free to share with patients and families. No account required.
