ICD Guidelines Ch. 9 Diseases of the Circulatory System Flashcards
This can ONLY be coded together when the Dr. links the two as due to HTN or implied hypertensive
HTN w/ Heart Disease
When HTN & Heart disease aren’t linked
code them separately
HTN w/ CKD is a cause and effect relationship & whenever documented it’s
coded the smae NOT LINKED
HTN Heart Disease & CKD are coded
when documented
Code the Heart Failure and CKD as
additional codes
Should be 3 codes
A casual relationship can be assumed in a pt. w/ both atherosclerosis & angina
unless documentation indicates the angina is due to something else
AMI happens within
4 Weeks or 28 days
AMI is considered old after
4 weeks or 28 days
Subsequent AMI can be coded when it happens within 4 weeks of the
1st one. The sequencing depends on documentation
Hypertension uses the same code
Essential, Malignant, Benign,
Sequencing 1st- I10
Hypertension in the setting of Heart Disease Dr. DOES NOT have to Link DX
1st- I11
2nd- I50.- or I51.4- I51.9 (specify Heart Failure)
Hypertensive Chronic Kidney Disease Dr. DOES NOT have to LINK DX
1st- I12
2nd- N18 ( To identify the Stage)
Hypertensive Heart & Chronic Kidney Disease Dr. does not have to link DX
1st- I13
2nd- I50 (specify the heart faliure)
3rd- N18 ( to identify the stage)
Dr. MUST specify the DX in Hypertension and
Cerebrovascular disease
Hypertension Cerebrovascular disease
1st- I60- I69
2nd- HTN code
Hypertensive Retinopathy
1st- I10 or H35.0
sequence w/ the reason for the encounter (RFE)
Secondary HTN is do to an underlying condition. Two codes are rquired. One for the cause, and one for the hypertension
1st- I15 or the Underlying condition
sequence w/ the RFE
Elevated blood pressure
ex: white coat syndrome
1st- RO3.0
HTN controlled by therapy
Hypertension controlled
1st- I10-I15
HTN not responding to therapy
Hypertension uncontrolled
1st- I10-I15
Document for HTN crisis, & use a code to identify the type of HTN
1st- I16, I10- I15 (sequence events)
Code pulmonary HTN, Code associated conditions or adverse effects of drugs and toxins.
1st- I27 (other pulmonary HTN)
2nd- I27.1, I27.2- (secondary HTN)
3rd- asociated conditions, or adverse effects of drug/ toxins sequence in reason for encounter
Ch. 15 During pregnancy (gestational HTN or Preclampsia
1st- O13 for gestational HTN and O14 for preclampsia
Atherosclerotic Coronary Artery disease ASHD & Angina
combo code w/ angina pectoris
1st- I25.11 (Native coronary artery) or
I25.7 (bypass grafts)
