Can I Practice Virtually Across State Lines?
That depends! Here’s a general guideline:
You must follow the laws in the state where the client is located
Some states allow unlicensed practice under wellness exemptions (e.g., California, Arizona)
If billing insurance, you almost always need a license in the client’s state
Licensing for Credentialing & Insurance Panels
If you plan to bill insurance:
You must be licensed in most states
Medicare requires a state license if available, in states where a license is not required, you must hold a CDR or CNS credential
Commercial insurance often requires either a license or RD credential
In some states (e.g., Washington), CNS candidates are eligible for licensing
