Frequently asked questions

Bill as H2001 only when services delivered cover approximately a half-day (commonly 3–4 hours), structured around therapeutic activities consistent with rehabilitation, not shorter session blocks.

Typically, no. H2001 represents a half-day block. Billing more than one unit in a single day usually requires special justification and is subject to payer policy limits.

This depends on the specific payer. Some payers may have a "two services per day" rule, but some services, like medication management, may be exempt. It is crucial to check with the payer's specific billing manual.
