Hypertensive Crisis Types and Coding

• Hypertensive Crisis is classified into
  hypertensive urgency and hypertensive emergency.
• Hypertensive urgency is extremely high blood
  pressure, where readings are 180/110 or higher,
  but there is no damage to the body's organs. In
  this stage, physicians may adjust or add
  medications, but rarely requires hospitalization.
• Urgency can be documented using ICD-10 code
• I16.0 hypertensive urgency
