Why this matters for your practice
The 80/20 rule is dangerous precisely because it is automatic. Most Medicare compliance involves judgement about whether services were clinically appropriate. The 80/20 rule removes that judgement: cross the threshold and a referral to the Professional Services Review is mandatory, regardless of how good your clinical reasons were. The consequences can include repayment of benefits, disqualification from Medicare, and reputational damage.
For a busy practice, especially one running high-volume or after-hours models, this is a number to actively monitor rather than discover after the fact.
How the threshold works
A practitioner triggers the rule if they render 80 or more professional attendances on each of 20 or more days within a 12-month period. The key points:
- It counts days, not totals. It is 20 separate days each with 80+ attendances, not 1,600 services overall.
- It applies to professional attendances (consultations), not every MBS item.
- Once met, it is a prescribed pattern of services, and referral to the PSR is mandatory.
What counts and what to watch
- Telehealth and after-hours attendances count toward the daily tally.
- Locums and contractors billing under their own provider number carry their own exposure.
- A single very busy day is not the problem. A repeated pattern of very high daily volumes is.
What happens after a trigger
A prescribed pattern referral sends the matter to the Professional Services Review, which examines whether the practitioner engaged in inappropriate practice. Outcomes can include agreements to repay Medicare benefits, reprimands, and partial or full disqualification from billing Medicare.
Common mistakes
- Thinking high volume is fine if every service was justified. The 80/20 trigger is mechanical, not clinical.
- Not monitoring daily attendance counts across the year.
- Assuming telehealth does not count. It does.
Frequently Asked Questions
What is the 80/20 rule in Medicare?
The 80/20 rule says that a practitioner who renders 80 or more professional attendances on each of 20 or more days in a 12-month period has engaged in a prescribed pattern of services. This triggers a mandatory referral to the Professional Services Review.
Does the 80/20 rule count total services or daily services?
It counts days. The trigger is 80 or more attendances on each of 20 or more separate days within 12 months, not a total number of services across the year. Twenty qualifying days, each with at least 80 attendances, meets the rule.
What happens if I breach the 80/20 rule?
Breaching the rule means an automatic referral to the Professional Services Review. The PSR examines whether inappropriate practice occurred and can require repayment of Medicare benefits, issue reprimands, and disqualify a practitioner from billing Medicare.
