Cardiac Diagnostic Coding
• VSD 745.4
• PDA 747.0
• Coarctation of the
Aorta – 747.10
• ASD – 745.5 – 745.8
• Tetralogy of Fallot
• 745.2
• Transposition of
Great Arteries
• 745.10 – 745.19
Heart failure
Congenital  Dx Coding
• If no specific term in ICD, use more
general terms in the AI, such as
– Anomaly, Defect, Deformity, etc.
• If anomaly is specified, but no code, use
code for other specified anomaly of that
type/site OR unspecified anomaly of that
general type/site
• Add’l codes for manifestations assigned
when specific codes not available
Congenital  Dx Coding
• Codes from Chapter 14 can be reported
for a patient of ANY age
• AKA - ASHD, coronary ischemia, and coronary
ateriosclerosis (atherosclerosis)
• Code 411.1 (unstable angina, crescendo angina,
preinfarction angina, and impending MI) as PDX
ONLY when NO underlying condition
determined and NO surgical intervention
• IF a CABG or PTCA is performed, 414.0x is
coded with additional code for unstable angina
CAD coding
• IF patient does NOT have hx of CABG,
assign code 414.01
• IF patient does have a history of CABG,
then assign appropriate code from 414.00,
414.02-414.05 range
– BUT must query Dr for specific artery
• 414.06 and 414.07 are used for CAD of a
transplanted heart
Acute MI - 410
• Two factors must be known:
– Site or type of AMI (4th digit)
• transmural, subendocardial
• check EKG interpretation for specific info
– Episode of care (5th digit)
• Initial, Subsequent, Unspec
• The 4th digit of 9 (unspecified site) & 5th digit of 0
(unspec. episode of care)
– NEVER used for inpatient encounters
– Query physician for clarification
– These can be used in outpatient settings
Acute MI – Episode of Care
• 5th digit used to indicate
– initial or
– subsequent episodes of care in the 8 weeks
after the MI
– It is safe to assume a MI admission is initial IF
the hx does not mention previous MI
Chronic/Healed MI
• Chronic MI or w/duration 8+ weeks - 414.8
• MI documented as old/healed - the coder
must determine if this is still being tx or
affecting care
• 412 is NOT assigned when current CAD is
• 412 is only assigned if it has an impact on
the current care
MI Example
• Pt admitted to Hospital A on 3/3 with severe chest pain, dx
as an anterolateral wall AMI (no hx of earlier care) 410.01
• Pt was transferred to University hospital later on 3/3 for
angioplasty 410.01
• Retransferred to Community Hospital on 3/6 to continue
recovery. Pt discharged on 3/8. 410.01
• Same pt readmitted to Community Hospital on 3/12 because
he was having severe chest pains. Extension of the
infarction was suspected but R/O 410.02
CAD/AMI Sequencing
• Patient adm. for angina due to CAD
– CAD is sequenced 1st w/ add’l code for angina
• Patient adm. w/unstable angina and CAD and AMI after
– AMI is sequenced 1st w/ CAD as an additional code
– Unstable angina not assigned, since progressed to AMI
• Patient adm. w/AMI and CAD; AMI code 1st w/ code for CAD
• Pt adm. w/impending MI and CH, AMI after admission
– AMI is sequenced 1st w/ appropriate codes for the CHF
• Note: NO 411 assigned w/code from 410 UNLESS
documented postmyocardial infarction syndrome,
postinfarction angina, or Dressler's syndrome
Heart Failure
• Diastolic vs Systolic
• Knowing systolic vs diastolic dysfunction is
– long-term treatments are different
– MS-DRG impact
Systolic heart failure (428.2x)
• More common
– dilation of left ventricle
– with impaired contraction of heart muscle
– decreased outflow of blood from the heart
• Heart contracts w/less force
– Can’t pump our as much blood as normal
– More blood remains in lower chambers and
accumulates in veins
• CAD is a common cause
Diastolic heart failure (428.3x)
• Normal left ventricle with impaired ability to
relax muscles between contractions
– heart is stiff and doesn’t relax normally
– results in the inability to receive, as well as
eject, blood.
– As in systolic dysfunction, the blood returning
to the heart then accumulates in the veins
• Often, both forms occur together (428.4x)
5th digits for 428.2-428.4
0 unspecified
1 acute
2 chronic
3 acute on chronic
Acute on chronic = patient w/chronic heart
failure now has superimposed acute flareup.
• Assign 5th digit based on documentation
• All codes for heart
failure include
– Dyspnea, orthopnea,
bronchospasm, acute
pulmonary edema
• Right Heart Failure –
usually follows leftsided heart failure; is
congestive heart
failure (includes leftsided heart failure)
– 428.0
Compensated (near-normal)
and Decompensated Heart
• Heart muscle compensation mechanisms
cardiac hypertrophy
raised arterial pressure
ventricular dilation
increased contraction force
• Code assignment is NOT affected by these
• Dilated heart, flabby heart muscles, normal
coronary arteries
• Types include
– Alcohol 425.5
– Congestive, constrictive, hypertrophic, obstructive
• In most cases tx focuses on mgt of CHF and in those
instances the heart failure, 428.0 or 428.1, is the
principal diagnosis, with cardiomyopathy, 425.4,
assigned as add’l dx
• Dual coding is required for cardiomyopathy due to other
conditions, such as amyloidosis or HTN
Heart Failure Examples
• Left heart failure with B9 HTN 428.1, 401.1
• Acute CHF due to HTN 402.91, 428.0
• CHF due to hypertensive heard disease
– 402.91, 428.0
• Acute pulmonary edema with L ventricular
failure 428.1
427.5 Cardiac Arrest
• This code is PDx ONLY when the underlying
cause CANNOT be determined
– ex: pt is in cardiac arrest when arriving at hospital
and cannot be resuscitated
• Can be add’l dx when cardiac arrest occurs
during admission and the pt is resuscitated or
resuscitation is attempted
• 997.1 - Cardiac arrest as a complication of
• DO NOT use these codes to indicate pt death
HTN code categories
• ICD-9-CM has 5 HTN categories to identify type
401 Essential hypertension
402 Hypertensive heart disease
403 Hypertensive renal disease
404 Hypertensive heart and renal disease
405 Secondary hypertension
• 401-404 show progression of disease progress
from vascular origin to end organs involved
• ICD-9-CM classifies HTN
– by type (primary/secondary) and
– nature (B9, malignant, unspecified)
• Hypertension described as controlled or history
of HTN usually refers to an existing HTN, if it is
still under tx, then code the HTN
• due to HTN (direct causal relationship) or
hypertensive (implied relationship) indicate that
the HTN has caused other problems
– Many combination codes
B9 or Unspecified HTN
• Unspecified or Hypertension, NOS is coded to
• The coder should NEVER assume that
hypertension is malignant or benign without
physician documentation
• "Benign" must be stated by the physician along
with hypertension to code 401.1
HTN Table
• In AI, under main term – Hypertension
• Subterms listed in 1st column
– use same AI conventions
• With, due to, hypertensive, etc.
• 2nd – 4th columns
– Malignant, B9, and unspecified
– Dr must document for coder to use Mal/B9
• Codes MUST be verified in TL
Hypertensive  Disease
• Includes cardiomegaly, cardiovascular disease,
myocarditis, degeneration of the myocardium, and
heart failure
• When the dx statement mentions both HTN AND
heart condition, but does NOT indicate a causal
relationship, separate codes are assigned
• 402 is a combination code for hypertensive heart
diseases (5th digit indicates presence of heart
failure), add’l code needed to specify type of heart
HTN and Renal Disease
• Dx statement has HTN AND renal disease
– ICD usually ASSUMES a cause/effect
relationship (403)
– 5th digit indicates presence of renal failure
– 403 does NOT include ACUTE renal failure
5th digits
0 - with CKD stage I - stage IV, or unspecified
1 - with CKD stage V or end stage renal disease
Appropriate 585 code is add’l code to id stage of
kidney disease
Heart AND Renal Disease
• 402 condition AND 403 condition exist
– 404 combination code is assigned
– 5th digit indicates if CHF, renal failure, or both
are present
• 0 – w/o heart failure & with chronic kidney disease
(CKD) stage I - stage IV, or unspec.
• 1 – w/heart failure, with CKD stage I - stage IV, or
• 2 - w/o heart failure, with CKD stage V or ESRD
• 3 - w/heart failure and with CKD stage V or ESRD
• Appropriate 585 code is add’l code to id stage of
kidney disease
HTN, DM, and CKD
• When dx indicates that both HTN AND DM
are cause of CKD, use two codes
– appropriate code from 403 OR 404 and
– 250.4x
– Add’l code for the stage of CKD
HTN w/other conditions
• Although HTN may occur with other
conditions and accelerate their
development, ICD does not have
combination codes for these
– Need multiple coding
• 796.2 - Elevated blood pressure w/o
specificity, NOT code from 401
– Must be documented by Dr, not just recorded
• Blood pressure readings vary, tend to
increase with age (white coat HTN)
• HTN dx must be based on a SERIES of
HTN Coding Examples
• CHF due to HTN
402.91, 428.0
• CHF with HTN
428.0, 401.9
• HTN, chronic kidney disease 403.91
• Main Terms

• AV Malformations
• Arteriosclerosis
• Emboli
• Phlebitis
AV Malformation
• Malformation (congenital) – see also
• Anomaly
– Arteriovenous
• sites
of Extremities
• Coder needs to determine
– 1) if native arteries or graft involved,
– 2) if progression of disease includes
A) claudication
B) rest pain
C) ulceration, or
4) gangrene
• Usually affects legs, but can be in arms
Progression of arteriosclerosis
• Intermittent claudication
(from Latin for “limping”)
• A) pain when walking
– As worsens, length of
walk before pain gets
shorter, rest stops pain
• B) rest pain
– Sitting down, resting no
longer gets pain to stop
• C) ulceration, or
• 4) gangrene
• When coding, each
stage includes the
previous one
• Ex: “claudication with
– Code only 440.23

• 92950
Electrophysiology (EP)
• Cardiac specialty
• Concerned with mechanism, spread, and
interpretation of electric currents arising
within heart muscle tissue and initiating
each heart contraction
Electrophysiology (EP)
• Assesses cardiac arrhythmias, by
(1) measuring cardiac electrical activation/conduction
(2) assessing electrical activation patterns (mapping)
(3) inducing/terminating arrhythmias (with PES)
(4) assessing risk for malignant arrhythmias and sudden
cardiac death
– (5) treating with ablation, and
– (6) assessing the effects of drug and electric interventions,
including device and ablative therapies
• The approach can be either invasive or noninvasive
EP procedures
• Insertion sites commonly include the
femoral, jugular, and, occasionally,
subclavian and cephalic veins
• If necessary, femoral arteries used to gain
access to the left side of heart and for
continuous direct blood pressure
Radiofrequency Ablation
• Nonsurgical procedure to tx some types of rapid
heart beats, usu. supraventricular tachyarrhythmias
• Physician guides catheter with electrode at tip to
muscle with accessory (extra) pathway
• Guided with real-time, moving X-rays (fluoroscopy)
• Mild, painless radiofrequency energy (similar to
microwave) is transmitted to extra pathway,
destroying carefully selected heart muscle cells in a
very small area (about 1/5 inch)
• 93650-93652
Cardiac Pacemakers and Pacing

• Pulse generators implanted internally OR attached
– Single chamber or dual chamber
• 1 lead in R heart (ventricle OR atrium)
• 2 leads in R heart (ventricle AND atrium)
– Surgical approach for lead(s) placement
• Epicardial –sternotomy/thoracotomy
• Endocardial - transvenous
Permanent Pacemaker
• Recommended to
correct some types of
bradycardia heart
blocks, afib
• A pulse generator is
implanted under the
skin in the upper
chest or abdomen
and lead wires are
also attached
Implantable Cardioverter
Defibrillator (ICD)
• Small device implanted into
the upper chest area
– accurately analyze and tx
cardiac arrhythmias
– ICD monitor senses abnormal
– sends one + electrical
impulses or shocks to heart,
restoring normal rhythm
– Painful!
• Components
– Pulse generator, leads,
– Pacing, shocks
Info Needed to Code
• Single or Dual Chamber
• Epicardial or Endocardial
• Insertion
– Initial, repair, replacement, upgrade
• Entire system or just a component (lead)
• Use of fluoroscopic guidance
• Non-Invasive Program Stimulation
• brief procedure to adjust ICD
– heart is stimulated into a rapid heart rate
– ICD delivers a shock or rapid pacing
sequence to restore a normal rhythm
– Physician can then adjust the ICD's
programming, if needed
– Pt is under anesthesia for the testing and able
to go home a few hours later
