Substance use halfway house
CMS description
Alcohol and/or drug abuse halfway house services, per diem
In the order to send them
Why these codes
A per diem residential setting for substance use; many plans exclude it, so check the umbrella too.
If a payer returns nothing
Payers don't all answer every service type. Send 30 (Health Benefit Plan Coverage) for the plan's general benefits.
