What Open Payments does not tell you

The limits of this dataset, stated plainly.

A lookup tool that only lists strengths is not a useful lookup tool. Here is what this data cannot do.

It cannot tell you about care quality

There is no outcome, complication, volume or patient-satisfaction data in Open Payments. A profile with zero payments says nothing about clinical skill.

It cannot establish causation

A payment and a prescription in the same year are two facts, not a mechanism.

It misses whole categories of relationship

Payments from companies without a Medicare-reimbursable product. Payments to non-teaching hospitals. Product samples. Unpaid advisory roles. Expert-witness income. Ownership of publicly traded stock bought normally.

It is only as good as the submissions

Companies self-report. CMS validates format and identity matching, not truth. Misattributions happen, particularly with common names.

It lags

Published annually in June for the prior calendar year. A relationship formed last month will not appear for up to eighteen months.

It is a starting point

The right use is as one input: a reason to ask a question, not an answer to it.
