Frequently asked questions

What is the 8-minute rule?

For Medicare, timed services are billed in 15-minute units, and a unit can be billed once at least 8 minutes are provided; we calculate units from documented minutes.

When is the KX modifier used?

KX is added when Medicare therapy spending passes the yearly threshold and the services are medically necessary and documented.
