icd 9 code for hypertension

Hypertension is a prevalent chronic condition, classified under the ICD-9 code of 401. The severity of hypertension allows for its categorization into distinct subtypes: essential hypertension (401.0), secondary hypertension (401.1), and hypertension with unspecified cause (401.9). These classifications facilitate medical documentation and statistical analysis, aiding healthcare professionals and researchers in gaining insights into the prevalence and patterns of the disease.

Essential hypertension is the most frequently encountered form, often without an identifiable cause and potentially linked to genetic predisposition, lifestyle choices, and environmental influences. Secondary hypertension arises as a result of other medical conditions, such as renal diseases, endocrine disorders, or the adverse effects of certain medications. The code for hypertension with unspecified cause is applied when there is insufficient information to determine if the hypertension is essential or secondary.

For individuals managing hypertension, it is crucial to regulate their dietary habits by limiting the consumption of salt and fatty foods while increasing the intake of vegetables and fruits. Additionally, engaging in regular physical activity, abstaining from smoking, moderating alcohol intake, and maintaining a positive mental outlook are beneficial in controlling blood pressure. Persistent elevation of blood pressure warrants timely medical consultation and treatment under a physician's supervision, rather than self-administering medication without guidance.
