In the world of outpatient therapy services, accuracy in billing is not just importantits essential for timely reimbursements and compliance with payer regulations. One of the most crucial guidelines in this area is the 8-minute rule, which determines how units of time-based therapy services are billed to Medicare and some private payers.

The best medical billing services understand that strict compliance with this rule is key to avoiding denials, reducing audits, and maximizing revenue. This article explores what the 8-minute rule is, why it matters, and how top-tier billing companies ensure accuracy and compliance in therapy billing.

What Is the 8-Minute Rule?

The 8-minute rule is a Medicare guideline used to determine how many units of time-based services (like physical, occupational, or speech therapy) a provider can bill for during a single patient encounter.

How the Rule Works:

• Therapy services are divided into time-based CPT codes, typically billed in 15-minute increments.

• Under the 8-minute rule, a provider must spend at least 8 minutes of direct one-on-one time on a time-based service to bill one unit.

• For multiple services, total time is calculated, and the number of billable units is determined based on specific ranges.

Failure to apply this rule correctly can lead to overbilling, underbilling, or rejected claims.
