Chapter 9: Diseases of Circulatory System (I00 – I99)

  • In hypertension blood pressure in your blood vessels is too high 140/90 mmHg or higher.
  • Elevated blood Pressure : Blood pressure increase conditionally not permanently.

Hypertension

  • Hypertension with Heart Disease we assign two codes I11 and I50.- to I51.
  • Hypertensive chronic kidney disease code from I12 and N18.- series codes we use
  • Hypertensive Heart and chronic kidney disease codes from combination category I13, I50.- to I51.- and then N18 series code
  • Hypertensive cerebrovascular disease codes from I60-I69
  • Hypertensive Retinopathy, code H35.0 along with I10 – I15 category

If a type 1 NSTEMI evolves to STEMI, assign the STEMI code. If a type 1 STEMI converts to NSTEMI due to thrombolytic therapy, it is still coded as STEMI.

What is NSTEMI and STEMI

NSTEMI: Non-ST-elevation myocardial infarction (NSTEMI). Partially blockage of one of the coronary arteries, causing reduced flow of oxygen-rich blood to the heart muscles.

STEMI: A heart attack with a completely blocked coronary artery is called a STEMI. STEMI stands for ST Elevation Myocardial Infarction. On a heart tracing there is a particular area that is called the ST segment.
