ZDoggMD on Defensive Medicine: How Fear of Lawsuits Is Making Care Worse and More Expensive

This article discusses ideas from ZDoggMD — Dr. Zubin Damania, MD , Stanford/UCSF-trained internist, founder of the Health 3.0 movement. Full archive: zdoggmd.com | YouTube @zdoggmd

ZDoggMD has included defensive medicine in his broader critique of what's broken in American healthcare: a significant portion of what physicians order, document, and refer is driven not by what's best for the patient but by what protects the physician from litigation. This creates enormous waste, exposes patients to unnecessary risk, and adds to the documentation burden physicians carry every day.

What Defensive Medicine Actually Costs

Estimates of defensive medicine's contribution to US healthcare spending range from $46 billion to over $200 billion annually, depending on methodology. The wide range reflects genuine uncertainty — it's difficult to cleanly separate "ordered because clinically indicated" from "ordered because the physician feared not ordering it." Physicians themselves often can't draw that line cleanly in real time.

What's clearer: surveys of physicians consistently find that the majority order tests, imaging, and referrals specifically to reduce liability risk rather than because they expect clinical benefit. That's defensive medicine — and it means a substantial fraction of healthcare spending is generating no patient benefit while creating downstream risks from false positives, incidental findings, and procedure complications.

The Documentation Connection

Defensive medicine has a direct documentation dimension: physicians write lengthy, comprehensive notes partly because they're afraid that an incomplete note will expose them to liability if the case goes wrong. The 3,000-word note for a routine visit isn't all billing optimization — some of it is covering every base that a plaintiff's attorney might scrutinize years later.

ZDoggMD has pointed out the irony: defensive documentation often makes notes less useful clinically (burying the signal in noise) without actually providing much liability protection, since courts care more about whether the right decision was made than whether it was exhaustively documented. The defensive documentation culture imposes real costs on physicians' time with minimal actual benefit.

What ZDoggMD Argues Would Help

Malpractice reform — particularly moving toward evidence-based safe harbor protections that shield physicians who follow clinical guidelines — is part of ZDoggMD's Health 3.0 system reform agenda. When physicians who follow evidence-based care are protected from liability for bad outcomes that weren't caused by negligence, the defensive medicine incentive weakens. This requires legislative action and is a long-term project. In the near term: reducing every other source of documentation burden so that even if defensive documentation remains, the total time tax is manageable.
