Electronic health records (EHRs) often contains ICD codes used for billing purpose. Is there any study/survey that looked at how often ICD codes in EHRs reflect the actual diagnosis?

1I'm not aware of a published study. It would be hard to get buy in from a practice to conduct this study because if the ICD codes did not match the EHR, the practice would be guilty of fraud. – De Novo Oct 10 '18 at 21:41

In many cases they do reflect the actual diagnosis. It depends on the disease in question.
eMerge network work on validation is for example here: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3715338. In that study, they used ICD-based definitions but also other available data.
Similar work in diabetes mellitus diagnosis is also published (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4416392/)
Validation research tries to arrive at positive predictive value. E.g., https://www.ncbi.nlm.nih.gov/pubmed/30480162
In Japan, the PPV for AMI was 82.5%. (https://www.ncbi.nlm.nih.gov/pubmed/30477501)

Nice job of editing, Frank. UserJT, please use this as an example of what good supporting references look like. – Carey Gregory May 30 '19 at 22:11
