Introduction Cardiac risk stratification is a very broad topic but simply can be defined as an assessment used to evaluate a patient's risk of developing cardiovascular disease (CVD) or the risk of a cardiac event occurring in noncardiac surgeries, also known as a perioperative risk assessment.
Encounter for screening for cardiovascular disorders. Z13.6 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2019 edition of ICD-10-CM Z13.6 became effective on October 1, 2018.
Other specified personal risk factors, not elsewhere classified. Z91.89 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2019 edition of ICD-10-CM Z91.89 became effective on October 1, 2018.
Any patient that is planned for a noncardiac surgery should be risk-stratified as it forces clinicians to perform a thorough evaluation. Devereaux reports an estimated 1.4 - 3.9% of surgical procedures are complicated by major cardiac events.

A preoperative examination to clear the patient for surgery is part of the global surgical package, and should not be reported separately. You should report the appropriate ICD-10 code for preoperative clearance (i.e., Z01. 810 – Z01.
Code Z13. 89, encounter for screening for other disorder, is the ICD-10 code for depression screening.
Encounter for other preprocedural examinationICD-10 code Z01. 818 for Encounter for other preprocedural examination is a medical classification as listed by WHO under the range - Factors influencing health status and contact with health services .
Definition: The Preoperative Diagnosis Section records the surgical diagnosis or diagnoses that are assigned to the patient before the surgical procedure, and is the reason for the surgery. The Preoperative Diagnosis is, in the opinion of the surgeon, the diagnosis that will be confirmed during surgery.

Cardiac risk stratification is a very broad topic but simply can be defined as an assessment used to evaluate a patient's risk of developing cardiovascular disease (CVD) or the risk of a cardiac event occurring in noncardiac surgeries, also known as a perioperative risk assessment.
Cardiac risk stratification is an essential evaluation among health professionals. In today's world, cardiovascular disease is the number one cause of death globally and a significant cause of morbidity. Individuals at high risk of developing cardiovascular disease should be identified so that preventative efforts can be made.
The remaining risk factors are modifiable and can be further categorized into include health conditions and lifestyle factors. Health conditions include hypertension, dyslipidemia, diabetes mellitus, and chronic kidney disease (CKD). Lifestyle factors include cigarette smoking, diet and exercise, obesity, and psychosocial factors. Hypertension has an abundant amount of evidence to support its role as a risk factor in developing CVD. A meta-analysis published in 2002 shows that blood pressure is “strongly and directly related to vascular (and overall) mortality,” showing that a difference of 20 mmHg of systolic or 10 mm Hg of diastolic pressure is associated with a nearly twofold difference in cardiovascular disease death rate.[7] Dyslipidemia, defined as elevated total or LDL cholesterol, low HDL cholesterol, disturbances in lipoprotein metabolism, have all been shown to be independently associated with CVD. [8][9] Diabetes mellitus is considered a coronary heart disease (CHD) equivalent[10]secondary to finding that patients with diabetes only had a similar risk of myocardial infarction compared to those without diabetes but with a prior myocardial infarction.[11] Chronic kidney disease is now also considered a CHD equivalent, just as diabetes mellitus is. Secondary to both proteinuria and a decreased glomerular filtration rate, it was shown that patients with even moderate renal impairment based on GFR and increased proteinuria were associated with an increase in all-cause and cardiovascular mortality compared to those with normal renal function.[12] Cigarette smoking is associated with a higher risk of myocardial infarction and is related to the amount used; however, the benefits of cessation are significant regardless of the amount or length of use. One study showed that smokers who stopped smoking had a risk similar to that of a nonsmoker within two years of quitting in a population of patients who had suffered a prior myocardial infarction.[13] Diets high in red meat and high-fat dairy products have been associated with having a higher risk of CHD.[14] A risk reduction was shown with diets high in fiber and daily consumption of fruits and vegetables. Exercise has been shown to reduce CHD risk and overall cardiovascular mortality. Obesity was shown to have a direct relationship with CVD risk. [15]
Non-modifiable risk factors are as follows: age, gender, and family history. Specifically, these risk factors are permanent, and there is very little that can be done to decrease an established risk from these factors. Several studies have been shown that the prevalence of CVD increases with age, where each decade of life above the age of 40 showed a significant increase in the prevalence of any vascular disease.[3] The male gender has been shown to have a baseline increased risk than females across several different populations.[4] Family history has been shown across multiple studies to be an independent risk factor for the development of CVD or future myocardial infarction, specifically parental family history. [5][6] Positive family history for CVD is described as any 1st-degree relative who has undergone death or development of CVD before the age of 55 for males or 65 for females.
Cardiovascular risk can be assessed through several different risk models accounting for separate risk factors, some overlapping with other risk models . No single risk model is the supreme choice, although the ACC/AHA published guidelines in 2013 recommending the use of the ACC/AHA pooled cohort hard CVD risk score in the United States. Regardless of the risk model that is chosen, patients are categorized in a low, intermediate, and high estimated 10-year risk for developing CVD. Based on the patient’s category, further therapy for primary prevention can be warranted, or lifestyle changes and reassessment is done. Primary medical prophylaxis usually involves aspirin or statin initiation but can involve medical therapy to reduce other risk factors, e.g., smoking cessation, depression, hypertensive medication, etc.
Emergency surgery is defined as a procedure in which life or limb is threatened if the patient is not taken to the operating room in less than 6 hours. In contrast to urgent surgery, where life or limb are threatened if not in the operating room within 6 to 24 hours.
Cardiovascular Disease AssessmentCardiovascular disease is categorized into four groups: coronary heart disease, cerebrovascular disease, peripheral artery disease, aortic atherosclerosis, and thoracic or abdominal aortic aneurysms . There are several established risk factors that can be further categorized into non-modifiable and modifiable risk factors. The importance of understanding the significance of risk assessment lies in the epidemiology of CVD. Cardiovascular disease is the number 1 cause of death globally and is projected to remain the world’s major disease burden, accounting for more than 23.6 million deaths per year by 2030.[1] It is a source of great morbidity and mortality as well as a large portion of economic loss, especially in low- to middle-income countries, as reported by the World Health Organization.[1] Reducing the incidence by primary prevention will play a great role; however, it is important to understand that medical therapy is only part of the overall solution. Adequate risk reduction through education will be paramount in risk reduction.
The major clinical predictors ( Table 1) of increased perioperative cardiovascular risk are a recent unstable coronary syndrome such as an acute MI ( documented MI less than 7 days previously), recent MI (more than 7 days but less than 1 month before surgery), unstable or severe angina, evidence of a large ischemic burden by clinical symptoms or noninvasive testing, decompensated HF, significant arrhythmias (high-grade atrioventricular block, symptomatic arrhythmias in the presence of underlying heart disease , or supraventricular arrhythmias with uncontrolled ventricular rate), and severe valvular disease.
Surgery-specific risk for noncardiac surgery can be stratified as high, intermediate, and low ( Table 3 ). 23 High-risk surgery includes major emergency surgery, particularly in the elderly; aortic and other major vascular surgery; peripheral vascular surgery; and anticipated prolonged procedures associated with large fluid shifts and/or blood loss. Intermediate-risk procedures include intraperitoneal and intrathoracic surgery, carotid endarterectomy, head and neck surgery, orthopedic surgery, and prostate surgery. Low-risk procedures include endoscopic and superficial procedures, cataract surgery, and breast surgery.
The overriding theme of these guidelines is that preoperative intervention is rarely necessary simply to lower the risk of surgery unless such intervention is indicated irrespective of the preoperative context. The purpose of preoperative evaluation is not simply to give medical clearance but rather to perform an evaluation of the patient’s current medical status; make recommendations concerning the evaluation, management, and risk of cardiac problems over the entire perioperative period; and provide a clinical risk profile that the patient, primary physician, anesthesiologist, and surgeon can use in making treatment decisions that may influence short- and long-term cardiac outcomes. The goal of the consultation is to identify the most appropriate testing and treatment strategies to optimize care of the patient, provide assessment of both short- and long-term cardiac risk, and avoid unnecessary testing in this era of cost containment.
The initial history, physical examination, and electrocardiogram (ECG) assessment should focus on identification of potentially serious cardiac disorders, including coronary artery disease (CAD) [e.g., prior myocardial infarction (MI) and angina pectoris], heart failure (HF), symptomatic arrhythmias, presence of pacemaker or implantable cardioverter defibrillator (ICD), or a history of orthostatic intolerance. 1 The presence of anemia may also place a patient at higher perioperative risk. 2–4
Class I: Conditions for which there is evidence and/or general agreement that a given procedure/therapy is useful and effective. Class II: Conditions for which there is conflicting evidence and/or a divergence of opinion about the usefulness/efficacy of performing the procedure/therapy.
Resting left ventricular function has not been found to be a consistent predictor of perioperative ischemic events. 32–40
All anesthetic techniques and drugs have known cardiac effects that should be considered in the perioperative plan. There appears to be no one best myocardium-protective anesthetic technique. 61–65 Therefore, the choice of anesthesia and intraoperative monitors is best left to the discretion of the anesthesia care team, which will consider the need for postoperative ventilation, cardiovascular effects (including myocardial depression), sympathetic blockade, and dermatomal level of the procedure. Advocates of monitored anesthesia, in which local anesthesia is supplemented by intravenous sedation/analgesia, have argued that use of this technique avoids the undesirable effects of general or neuraxial techniques, but no studies have established this. Failure to produce complete local anesthesia/analgesia can lead to increased stress response and/or myocardial ischemia.
