How 2018 Impacts ICD-10-CM Cardiology Diagnosis Coding

How 2018 Impacts ICD-10-CM Cardiology Diagnosis Coding

For cardiology, the focus of ICD-10 is generally on increased specificity and documenting the downstream effects of the patient’s condition. Acute myocardial infarction, or what is more commonly known as AMI, had a definition change when the nation’s healthcare system switched from ICD-9-CM to ICD-10-CM in 2015. So when documenting AMI in ICD-10-CM, here’s a reminder to keep the following in mind before we look at 2018 changes:

  • Time frame: AMI will now be considered “acute” for four weeks from the time of the incident (remember that this is a revised time frame from ICD-9, which was a period of eight weeks).
  • Episode of care: ICD-10 does not capture episode of care (e.g. initial, subsequent, sequelae).
  • Subsequent AMI: ICD-10 allows coding of a new MI that occurs during the four-week “acute period” of the original AMI.
