Abnormal results of cardiovascular function studies

Not billableICD-10-CM diagnosis code.

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 3 more specific codes instead:

R94.30 Abnormal result of cardiovascular function study, unspecified
R94.31 Abnormal electrocardiogram [ECG] [EKG]
R94.39 Abnormal result of other cardiovascular function study

What has happened to this code

Every change the publisher made, from 2012 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.

FY2012 Added to the draft code set draft Abnormal results of cardiovascular function studies
