Medicare’s 8-Minute Rule Therapy: A Complete Guide

When it comes to therapy billing, some regulations are important and frequently misunderstood, as Medicare’s 8-minute rule. This rule governs how therapists bill for time-based facilities under the Medicare Part B and confirms fair and accurate repayment for the time spent directly treating patients. If applied incorrectly, the 8-minute Rule can lead to claims denials, compliance issues, and income loss. This guide explains the rule in detail, delivers examples, and helps you confidently apply it in your day-to-day billing. 

What Is The Medicare 8-Minute Rule?

The Medicare 8-minute rule was established in April 2000 to standardize billing for time-based therapy facilities that apply to outpatient therapy delivered involving:

• Private practice therapists.
• Skilled nursing and rehab facilities.
• Home health agencies for Medicare Part B services)Hospital outpatient departments, involving ERs.

Under this rule, therapists must deliver at least eight minutes of one-on-one, expert therapy to bill for a single time code unit. Medicare uses 15-minute increments to measure time-based codes, but because patient interactions rarely fit perfectly into 5-minute blocks, the rule accounts for the remaining time.

Generally put: 

• If 8 or more minutes stay after dividing the total method time by 15, you can bill for one additional unit.
• If 7 or fewer minutes stay, you cannot bill for another unit.

How to Calculate Billable Units?

To correctly determine billable under Medicare’s 8-Minute Rule, follow these steps:

• Add the total minutes of time-based facilities provided in a single session.

• Divide by 15 to calculate the number of whole units.
• Check the remaining minutes:
• If 8 – 22 minutes, bill 1 unit.
• If 23 – 37 minutes, bill 2 units.
• If 38 – 52 minutes, bill 3 units, and so on.
• If leftover minutes are 8 or more, bill for one more, bill for one more unit. 

Timed Vs. Service-based CPT codes

Understanding the difference between time-based and facilities-based CPT codes is essential when applying the 8-minute rule.

1. Time-based Codes (Timed Codes)

Billed in 15-minute units and based on the time spent in direct one-on-one therapy. Examples involve

• 97110: Therapeutic Exercise.

• 97140: Manual Therapy.

• 97112: Neuromuscular Re-Education.

• 97035: Ultrasound.

• 97761: Prosthetic Training.

• 97116: Gait Training.

• 97535: Self-care/ Home Management Training.

1. Service-based Codes 

Billed once per session, regardless of time spent. These facilities do not rely on one-on-one interaction. Examples involve

• 97010: Hot/Cold Packs.

• 97014: Unattended Electrical Stimulation.

• 97150: Group Therapy.

• 97164: PT Re-Evaluation.

Pro Tips for Staying Compliant

Here are some smart tips mentioned below:

• Deliver ongoing staff training on medicare documentation and billing.
• Conduct regular internal audits to catch errors early.
• Maintain detailed treatment notes indicating time spent and facilities provided.
• Stay updated on CMS policy transformations and updates to therapy codes.
• Meet Billing experts for complicated conditions or unusual combinations of facilities.

AMA Rule Of Eight Vs Medicare’s 8-minute Rule

While Medicare uses aggregate time across all timed codes, the American Medical Association applies the Rule of Eighths per code.

Examples:

• 8 minutes of 97110 (Therapeutic exercise)
• 8 minutes of 97140 (Manual Therapy)

Under AMA rules, you can bill 1 unit of every code. Under Medicare’s 8-minute rule, you can bill only 1 total unit.
