ICD-10 can be tricky to master with the sheer number of diagnoses to choose from, sequencing rules, and special notes. However, you don’t have to sacrifice precious dollars in your cardiology practice.
Bust these four myths to streamline your heart failure claims.
Myth 1: Acute and Chronic Heart Failure Develop at Same Rate
Truth: Acute heart failure develops suddenly, and the symptoms are initially severe. On the other hand, chronic heart failure usually develops slowly, over time.
“Patients with chronic heart failure have a previous history of heart failure and are on long-term management such as medications to control the heart failure,” says Carol Hodge, CPC, CDEO, CCC, CEMC, certified medical coder of St. Joseph’s Cardiology in Savannah, Georgia explains. “Chronic heart failure is an established form of heart failure that can be controlled, but not cured.”
Coding solution: If the physician documents acute diastolic congestive heart failure, you would report I50.31 (Acute diastolic (congestive) heart failure). However, if the physician documents chronic diastolic (congestive) heart failure, you would report I50.32 (Chronic diastolic (congestive) heart failure).
Myth 2: ADHF Doesn’t Involve Worsening of Heart Failure Symptoms
Truth: Acute on chronic heart failure (ADHF) is the sudden symptomatic worsening of heart failure (established known heart failure), says Julie-Leah J. Harding, CPC, CPMA, CEMC, CCC, CRC, CPEDC, RMC, PCA, CCP, SCP-ED, CDIS, AHIMA-approved ICD-10 trainer and ambassador and director of revenue operations-cardiovascular surgery at Boston Children’s Hospital in Boston, Massachusetts.
ADHF typically includes dyspnea with physical activity and or lying flat, the patient may have gasping for breath while walking, lower extremity swelling, fatigue, pulmonary edema (chest congestion), palpitations, loss of appetite, weight loss, low urine output, confusion and memory issues, according to Harding.
When chronic heart failure becomes uncontrolled, it is referred to as acute on chronic, and symptoms such as increased shortness of breath and pedal edema, may occur, according to Hodge.
“The worsening of these symptoms on top of the chronic condition is referred to as ‘acute on chronic,’” Hodge explains. “Once the acute phase isresolved, it is returned to being referred to as ‘chronic.’”
Coding solution: The physician documents acute on chronic right heart failure. You should report I50.813.
Myth 3: Specificity Not Important in Heart Failure Documentation
Truth: When it comes to heart failure documentation, specificity is vital. As Harding emphasizes, “You can offer any magnitude of ICD-10 codes, but if it is not documented, you cannot report them.”
“The most common mistake I see in reporting heart failure is that documentation only supports heart failure, unspecified,” Hodge says. “Providers need to be educated to document whether the heart failure is systolic, diastolic or combined. And, is it right or left heart failure? “
Harding talks about her experience from the congenital heart disease perspective.
“In the congenital heart disease world, most of our patients have a form or element of heart failure, according to Harding. “Our struggle, and it is common in the acquired world as well, is the lack of specificity in provider/clinician documentation.”
We seldom receive “acute,” “chronic,” or “acute on chronic” written in the patient record, Harding adds. We often query the providers for clarification.
Myth 4: You Can Ignore “Code First” Notes
Truth: You should also pay close attention to “code first” notes in ICD-10.
For example, a “code first” note under category I50- (Heart failure) tells you to sequence heart failure due to hypertensive heart and chronic kidney disease.
A common error she sees is coders not using the combination codes or the hypertensive with heart disease codes, according to Hodge.
“These codes should be used to indicate hypertensive heart disease followed by the code for the type of heart failure,” Hodge adds. “Kidney disease very often occurs with hypertension and congestive heart failure, and those guidelines should be followed to correctly sequence those codes.”
Coding solution: The physician documents that the patient has hypertensive heart and chronic kidney disease with acute systolic (congestive) heart failure and with stage 5 chronic kidney disease. You would report the codes in the following order: I13.2 (Hypertensive heart and chronic kidney disease with heart failure and with stage 5 chronic kidney disease, or end stage renal disease); I50.21 (Acute systolic (congestive) heart failure); N18.5 (Chronic kidney disease, stage 5).
