how do you code uncontrolled hypertension? Hypertension, whether uncontrolled, untreated or not responding to current medication, is assigned code I10. An instructional note provided for categories I10-I15 states to use an additional code to identify exposure to environmental tobacco smoke (Z77. You may ask, What are ICD 10 codes used for?
There are many causes for hypertensive crisis and they can include:
Essential (primary) hypertension: I10 In ICD-9, essential hypertension was coded using 401.0 (malignant), 401.1 (benign), or 401.9 (unspecified). ICD-10 uses only a single code for individuals who meet criteria for hypertension and do not have comorbid heart or kidney disease.
Malignant hypertension is very high blood pressure that comes on suddenly and quickly. The kidneys filter wastes and excrete fluid when the pressure of blood in the bloodstream forces blood through the internal structures of the kidney.
ICD-10 requires first using an I12 code for the combined diagnosis of hypertension and chronic kidney disease:I12. 0, Hypertensive chronic kidney disease with stage 5 chronic kidney disease or end-stage renal disease,I12.
In malignant hypertension, the vascular damage is acute, and renin release is a very important part of the pressure increase. In benign, essential hypertension, vascular damage is chronic, and its most important pressure-raising influence is sodium retention.
Malignant hypertension is extremely high blood pressure that develops rapidly and causes some type of organ damage. Normal blood pressure is below 120/80. A person with malignant hypertension has a blood pressure that's typically above 180/120. Malignant hypertension should be treated as a medical emergency.
Other causes of malignant hypertension include any form of secondary hypertension; complications of pregnancy, ie, preeclampsia and eclampsia; use of cocaine, monoamine oxidase inhibitors (MAOIs), or oral contraceptives; and the withdrawal of alcohol, beta blockers, or alpha stimulants, such as clonidine.
When a primary malignancy has been previously excised or eradicated from its site and there is no further treatment directed to that site and there is no evidence of any existing primary malignancy, a code from category Z85, Personal history of malignant neoplasm, should be used to indicate the former site of the ...
If chronic kidney disease is documented with hypertension, a combination code from I12 — hypertensive chronic kidney disease — should be reported. Documentation needs to identify the stage as 1-5 or end stage renal disease (ESRD) in order to report an additional code from category N18 — chronic kidney disease.
In ICD-10, the diagnosis codes are simplified and the hypertension table is no longer necessary.
Accelerated hypertension is defined by retinal damage, including hemorrhages, exudates and arteriolar narrowing. The additional presence of papilloedema constitutes malignant hypertension, which is usually associated with diastolic blood pressure greater than 140 mmHg.
Accelerated hypertension (also called malignant hypertension) is a disease characterized by a rapid and sudden increase in blood pressure over the baseline level that, if untreated, poses a threat of damage to organs and tissues.
Malignant hypertension is a complication of hypertension characterized by very elevated blood pressure, and organ damage in the eyes, brain, heart and/or kidneys. Benign hypertension is a condition of mild to moderate hypertension.
In ICD-9, essential hypertension was coded using 401.0 (malignant), 401.1 (benign), or 401.9 (unspecified). ICD-10 uses only a single code for individuals who meet criteria for hypertension and do not have comorbid heart or kidney disease. That code is I10, Essential (primary) hypertension.
Malignant hypertension is extremely high blood pressure that develops rapidly and causes some type of organ damage. Normal blood pressure is below 120/80. A person with malignant hypertension has a blood pressure that's typically above 180/120. Malignant hypertension should be treated as a medical emergency.
Hypertensive Heart and Chronic Kidney Disease: The codes in category I13, Hypertensive heart and chronic kidney disease, are combination codes that include hypertension, heart disease and chronic kidney disease, and should be used when there is hypertension with both heart and kidney involvement. If heart failure is present, an additional code ...
When assigning diagnosis codes for hypertension (HTN), there is an presumed causal relationship between hypertension and heart involvement, and between hypertension and kidney involvement. The ICD-10-CM Official Guidelines for Coding and Reporting (I.C.9) instruct, “These conditions should be coded as related even in the absence of provider documentation explicitly linking them, unless the documentation clearly states the conditions are unrelated.” The Guidelines further specify:
CKD should not be coded as hypertensive if the physician has specifically documented a different cause. The appropriate code from category N18 should be used as a secondary code with a code from category I12 to identify the stage of chronic kidney disease.
