NOTICE for the 2016 NAMCS Public Use Data File and 2016 NHAMCS Emergency Department Public Use Data File: A problem was found with the checkbox for CHF (Congestive Heart Failure) in the item: “Regardless of the diagnoses written above, does the patient now have:”. This checkbox is typically edited to ensure that any diagnoses of CHF reported in the survey items DIAG1-DIAG5 (Diagnosis #1 – Diagnosis #5) are also reflected in the CHF check box. It was recently discovered that the ICD-10-CM codes I50.1-I50.9 (Heart Failure) were not included in the edit. In all, 28 NAMCS records and 45 NHAMCS ED records with a diagnosis of Heart Failure reported in DIAG1-DIAG5 should have had the CHF checkbox checked but did not. More information is available here.
