Two codes are required: one to identify the underlying etiology and one from category I14 to identify the hypertension. Secondary hypertension is due to an underlying condition. The sequencing is based on the reason for the encounter.

Subcategory H35.0, Background retinopathy and retinal vascular changes, should be used with a code from category I10-I15, Hypertensive disease to include the systemic hypertension. 4) Hypertensive cerebrovascular diseaseįor hypertensive cerebrovascular disease, first assign the appropriate code from categories I60-I69, followed by the appropriate hypertension code. If a patient has hypertension, heart disease and chronic kidney disease, then a code from I13 should be used, not individual codes for hypertension, heart disease and chronic kidney disease, or codes from I11 or I12.Įxample: CKD, stage 3, with CHF due to Hypertension is coded to I113.0 (Hypertensive heart and chronic kidney disease with CHF, Stage 3 CKD), I50.9 (Heart failure, unspecified), and N18.3 (CKD, Stage 3).ĩ. The Includes note at I13 specifies that the conditions included at I11 and I12 are included together in I13. The codes in category I13, Hypertensive heart and chronic kidney disease, are combination codes that include hypertension, heart disease and chronic kidney disease. See Section I.C.14 Chronic kidney disease
The appropriate code from category N18, Chronic kidney disease, should be used as a secondary code with a code from category I13 to identify the stage of chronic kidney disease. If heart failure is present, assign an additional code from category I50 to identify the type of heart failure. Assume a relationship between the hypertension and the chronic kidney disease, whether or not the condition is so designated. 3) Hypertensive heart and chronic kidney diseaseĪssign codes from combination category I13, Hypertensive heart and chronic kidney disease, when both hypertensive kidney disease and hypertensive heart disease are stated in the diagnosis. If a patient has hypertensive chronic kidney disease and acute renal failure, an additional code for the acute renal failure is required.ĩ. See Section I.C.14 Chronic kidney disease. 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. Unlike hypertension with heart disease, ICD-10-CM presumes a cause-and-effect relationship and classifies chronic kidney disease with hypertension as hypertensive chronic kidney disease. 2) Hypertensive chronic kidney diseaseĪssign codes from category I12, Hypertensive chronic kidney disease, when both hypertension and a condition, classifiable to category N18, Chronic kidney disease (CKD), are present. Sequence according to the circumstances of the admission/encounter.ĩ. The same heart conditions (I50.-, I51.9) with hypertension, but without a stated causal relationship, are coded separately. Use an additional code from category I50, Heart failure, to identify the type of heart failure in those patients with heart failure. Heart conditions classified to I50.-I51.9, are assigned to a code from category I11, Hypertensive heart disease, when a causal relationship is stated (due to hypertension) or implied (hypertensive). If the right side is affected, the default is dominant.If the left side is affected, the default is non-dominant.
#Paroxysmal atrial flutter icd 10 plus#
Combination codes include Coronary Artery Disease (CAD) plus all types of Angina.The types of hypertension (benign, malignant, accelerated, etc.) are all listed as modifiers in I-10.For the I-10 Corner this week, we’re focusing on diagnostic coding guidelines, plus a few examples,for Chapter 9: Diseases of the Circulatory System (I00-I99)
