TIA


Stroke
Transient episode of
neurological dysfunction
caused by focal ischemia
to brain, spinal cord, or
retina without acute
infarction.
Lasts at least 30 seconds
and up to several days (3
days average).


Sudden neurological
deficit related to brain
necrosis caused by either
infarction (80%) or
hemorrhage (20%).
Strokes can be defined by
imaging studies or
persistent symptoms,
typically > 3 days.
 Acute/subacute
infarction on CT or MRI
on CT or MRI
 Significant neurological deficits persist at
time of discharge
 Hemorrhage

study to the neurological condition”

and/or cerebral atherosclerosis.

Recurrent TIAs or strokes usually different areas of the brain
(not always with same symptoms)

No significant obstruction of pre-cerebral vessels

Patient with history of afib was admitted for
transient aphasia lasting 30 minutes. The
patient has a h/o afib but is not on any
medical treatment. TIA was diagnosed and
patient was treated with Lovenox and
Coumadin in the hospital then discharged on
Coumadin. The coder assigned TIA as the
PDX. Final DRG = 69.

Patient presented with transient right arm
weakness & numbness. Head CT showed no acute
infarcts. Carotid U/S showed 80% left carotid
stenosis. The final diagnosis was TIA. Patient is to
f/u for OP left carotid endarterectomy. The coder
assigned 433.10 (CAS) as the PDX. Final DRG = 68.

Heart failure is a clinical syndrome resulting
from a failure of the heart to supply the body’s
need for circulation. This may be a structural
(valve) or functional (heart muscle weakness)
disturbance.

ETIOLOGY: Coronary artery disease; hypertension;
valvular; primary cardiomyopathy

ANATOMICAL: Left, right, or biventricular

TYPE (PHYSIOLOGICAL):
Diastolic only (preserved ejection fraction)
Systolic heart failure
Combined

ACUITY: Acute, chronic, or both
Left Heart Only***
 Left ventricular abnormal function
 Signs: Pulmonary congestion (effusion; edema)
Right due to Left (Combined)***
 Most common cause of Right HF is Left HF
 Signs: Pulmonary and peripheral congestion
 Abnormal left ventricular function with elevated RH pressures
Right Heart Failure Only
 Underlying lung disease or congenital heart disease with significant
shunting
 Signs of peripheral congestion: swollen liver; ascites; peripheral edema;
pleural effusions; Jugular vein distention
 Peripheral congestion with pulmonary hypertension and RV pressures with
normal Wedge pressure (Pulmonary venous pressures or PCWP)
***Represents 95% or more of HF

failure)

Symptoms & Signs: SOB, orthopnea, paroxysmal nocturnal

edema +/-.

Radiographic signs of volume overload
- Pulmonary vascular congestion
- pleural effusions (usually bilateral)
- interstitial edema
- pulmonary edema
- small pericardial effusions

Elevated BNP. This lab test if elevated only affirms the
patient has CHF. It should not be used to make the
diagnosis of acute CHF. Chronic CHF has an elevated BNP.
If BNP is not elevated this suggests patient may not have
CHF; however, there are few instances of where acute CHF
can occur without elevated BNP, particularly isolated right
heart failure.


Volume/fluid overload is integral to CHF and not coded
separately unless MD says not due to heart failure. CC: 3rd
Qtr 1996; 2nd Qtr 2001
If a person is admitted for fluid overload due to missed
dialysis and has a h/o CHF, CHF is used as the PDx unless the
MD indicates fluid overload was not due to CHF. CC: 2nd Qtr
2001; 3rd Qtr 2007
Treatment of volume overload (pre-load reduction) is the
mainstay of treatment for ESRD patients. Dialysis is the
main mode of therapy acutely. This is the case regardless of
whether the patient has CHF or purely volume overload.

Acute pulmonary edema with heart disease is coded to CHF
unless the physician states the pulmonary edema is not
related.

If a person has an elevated BNP with LV dysfunction on Echo
clarify the nature of the volume overload.
TACO syndrome is a form of volume overload due to
transfusion. Acute pulmonary edema is not coded separately.

 Do
not code unspecified pulmonary edema
(514) as a CC if the cause is CHF. Pulmonary
edema is integral to CHF. If CHF or
acute/decompensated HF is not documented
you should try to clarify.
