ICD-10 Ch 9 Circ-P1

Dx of Circulatory System- HTN, CKD

Hypertension High Blood Pressure
What is one of the most common conditions reported with codes from Chapter 9? Hypertension
Malignant hypertension AKA accelerated hypertension; a severe form of hypertension
What are some symptoms of malignant hypertension? headaches, blurred vision, dyspnea, uremia; BP > 200/140mm Hg
What is the prognosis for a patient with malignant hypertension? poor
What is usually the outcome of malignant hypertension? permanent organ failure
Benign hypertension continuous mild hypertension that can usually be controlled with medication.
Is a coder allowed to determine whether a patient has hypertension based entirely on the blood pressure reading recorded in the medical record? No. The provider must document a diagnosis of hypertension
How long would a patient with benign hypertension be expected to live? a long life.
What are the dangers to benign hypertension? If untreated, it becomes an important risk factor in coronary heart and cerebrovascular disease.
What is the expected course of malignant hypertension? abrupt onset, runs its course in months; causes irreversible organ damage; often ends in renal failure or cerebral hemorrhage.
What causes essential hypertension? the cause is unknown.
Hypertensive heart disease Refers to secondary effects on the heart of prolonged, sustained, systemic hypertension.
What causes hypertensive heart disease? The heart has to work against increased resistance. The primary effect is increased thickening of the left ventricle, which may eventually lead to heart failure.
Differentiate between controlled hypertension and uncontrolled hypertension. Controlled hypertension is benign and controlled by medications or other treatment. Uncontrolled HTN is malignant, untreated, or not responding to medications or other treatments.
What code is used for controlled HTN? for uncontrolled HTN? I10 is used for both.
If HTN is secondary to another condition, how is HTN coded? The underlying condition is coded first. Then the HTN is coded from I15 category.
What would be underlying conditions that would lead to secondary HTN? renal disorder, endocrine disorder, other secondary HTN, or unspecified.
How is sequencing of code determined for secondary HTN? Sequencing depends on the reason for the visit/encounter
If HTN is transient, what code should be used? R02.0 Elevated BP reading without diagnosis of HTN.
If a patient was previously diagnosed with HTN, when would the coder use code R02.0 Elevated BP reading without diagnosis of HTN? Never
Proteinuria large amount of protein in the urine that results from renal disease or other abnormal condition
If the patient is pregnant, how is HTN coded? Use codes from Chapter 15, Ob - pregnancy codes for HTN, O13.- or O14.-
If a patient has both Hypertensive heart disease and CKD (which include HTN), what diagnosis codes should be used? Use combination codes from I13.
If heart failure is present in patient has both Hypertensive heart disease and CKD, what diagnosis codes should be used? I13 for HTN heart dx and CKD; Add I50 to identify the Heart failure.
If CKD is identified by any dx code, what code should be added? N18 as a secondary code to identify the stage of CKD.
The codes in category I13 are what kind of codes and include what condition(s)? combination codes including HTN, heart disease, CKD.
If an appropriate I13 code is present, is it okay for the coder to use separate diagnosis codes? No. If and I13 code exists, I11 and I12 should not be used because I13 combines these conditions .
If a patient has both acute and chronic renal failure, what diagnosis is coded? Both chronic and acute using two separate codes.
How many diagnosis codes are needed to correctly code CKD, HTN and chronic dialysis? Three. CKD stage code, HTN code, chronic dialysis Z code
How many diagnosis codes are needed to correctly code ESRD, HTN and chronic dialysis? Three. CKD stage code, HTN code, chronic dialysis Z code.
How many diagnosis codes are needed to correctly code CKD NOS, HTN and chronic dialysis? Three. CKD stage code, HTN code, chronic dialysis Z code.
