- HTN: Systolic blood pressure (SBP) of 130mm Hg or more and/or diastolic blood pressure (DBP) of more than 80mm Hg
- HTN Crisis: Generic term to describe hypertensive urgency or hypertensive emergency, typically seen with elevated blood pressure readings of 180/120 or higher
- HTN Urgency: Elevated blood pressure, >180/120, without evidence of end organ damage
- HTN Emergency: Elevated blood pressure, >180/120, with evidence of end organ damage
- Resistant HTN: High blood pressure that does not respond to antihypertensive drugs
Key defining characteristic between HTN Urgency and HTN Emergency is the presence of end organ damage.
Examples of end-organ damage:
- HTN Encephalopathy
- Aortic Dissection
- Pulmonary Edema
Hypertensive Crisis, Emergency, and Urgency are classified as the code grouping I16 with the instructions to code also any identified hypertensive disease (I10-I15).
Review pertinent Coding Clinics related to HTN such as:
- AHA Coding Clinic, Fourth Quarter 2016, pg. 26 ICD-10-CM New/Revised Codes: Hypertensive Crisis, Urgency and Emergency
- AHA Coding Clinic, Fourth Quarter 2023, pg. 23-25: A new subcategory I1A, other hypertension, has been created with a new code to describe resistant hypertension (RH) (I1A.0). When assigning code I1A.0, the specific type of hypertension, such as essential or secondary hypertension is sequenced first.
CDI Best Practice Considerations
- Hypertensive Crisis (I16.9) and Hypertensive Emergency (I16.1) are both classified as CC’s, whereas Hypertensive Urgency (I16.0) is a non-CC.
- Providers often will document “malignant HTN” and “accelerated HTN,” thinking they have included the required specificity. However, these are outdated terms and index to Essential (primary) HTN (I10), a non-CC. Query for further specificity when diagnostic criteria are met.
- In HTN Emergency patients, ensure the diagnosis of the end-organ damage is documented and supported by clinical indicators in the record. Query for specificity/clarification as needed.
- Review documentation of HTN Urgency closely, querying when criteria is met to specify as HTN Emergency.
- Resistant HTN is not classified as a CC or MCC. Review the record thoroughly for clinical indicators and treatment to support querying for HTN Crisis/Urgency/Emergency when appropriate.
Differentiating between HTN Urgency & Emergency can also be see in treatment regimen:
Review the H&P closely for reported symptoms and physical exam findings. Note that physical exam findings will vary depending on target organ, but some common symptoms & findings to review for include:
