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
