Arteriosclerotic heart disease (ASHD), commonly known as coronary artery disease, remains a leading cause of morbidity and mortality in the United States.
Recent data from the Centers for Disease Control and Prevention (CDC) indicate that in 2024, heart disease was responsible for 702,880 deaths, accounting for one in every five deaths nationwide.
Arteriosclerotic Heart Disease, often referred to as ASHD or coronary artery disease, is characterized by the thickening and hardening of the walls of the coronary arteries due to plaque buildup.

This process, known as atherosclerosis, restricts blood flow to the heart muscle, which can lead to angina, myocardial infarction (heart attack), and other cardiac complications. ASHD is a primary form of cardiovascular disease and a leading cause of morbidity and mortality globally.
The transition from ICD-9 to ICD-10 coding brought significant improvements in how ASHD and other cardiovascular conditions are classified. Here’s a quick overview of the main additions and improvements in the ICD-10 code system for ASHD compared to ICD-9:
These improvements in ICD-10 provide a clearer picture of the patient's health status, improving the documentation and management of cardiovascular conditions.
The ICD-10 coding system, which offers greater specificity than its predecessor, ICD-9, enables more precise documentation of ASHD and related cardiovascular conditions.
In the ICD-10 classification, ASHD is primarily coded as I25.10, which refers to atherosclerotic heart disease of the native coronary artery, unspecified. This code is used when the diagnosis does not specify the exact type or cause of the disease.
While ASHD addresses the broader spectrum of coronary artery diseases, physical therapists need to know the standard insurance payers and their claim amounts for each type of ASHD. Let’s explore the common claim amounts for the ICD-10 series for I25.10 ASHD curated by SPRY PT.
This table helps you with a quick reference of procedure codes, claim amounts, and ICD-10 codes by insurance payer. It helps physical therapists and medical experts in accurate billing, documentation, and efficient communication with insurers.
Note: Claim amounts are approximate, and additional ICD-10 codes may apply. Please verify the exact billing details with SPRY PT.

The ICD-10 classification system for ASHD defines specific codes to represent different stages and symptoms of ASHD, essential for accurate diagnosis and treatment.
This code refers to Arteriosclerotic Heart Disease (ASHD), in which there is hardening and narrowing of the coronary arteries due to plaque buildup. Still, the patient is not experiencing angina pectoris (chest pain).
Essentially, this means the patient has ASHD without any symptoms of angina. The condition is present, but it has not yet caused chest pain or other related symptoms. The patient might be asymptomatic or experiencing other non-angina-related symptoms, or the disease may be detected incidentally.
This code is used when ASHD in the native coronary arteries has progressed to the point where it causes angina pectoris. Angina pectoris is chest pain or discomfort that occurs when the heart muscle doesn't get enough oxygen-rich blood.
In this case, the plaque buildup and narrowing of the coronary arteries are causing reduced blood flow, leading to symptoms of angina. This is typically associated with stable angina, which occurs predictably during physical activity or stress.
This code applies when the patient has ASHD and is experiencing unstable angina, which is a more serious and unpredictable form of chest pain. Unlike stable angina (which occurs predictably), unstable angina can occur at rest or with minimal exertion and may last longer.
It is a medical emergency and requires immediate attention because it can be a precursor to a heart attack. This type of angina suggests that the plaque in the coronary arteries has ruptured, leading to blood clot formation, further narrowing the arteries, and worsening oxygen delivery to the heart.
This code is used when the patient has ASHD and experiences angina pectoris but also has documented coronary artery spasm. A coronary artery spasm is when the muscles in the walls of a coronary artery suddenly constrict or tighten, temporarily narrowing or closing the artery.
This can cause chest pain or discomfort even in the absence of plaque buildup, but it often occurs in conjunction with ASHD. Spasms can be triggered by stress, drugs, or other factors and can increase the risk of heart attacks if the spasms are severe or prolonged.
This code refers to ASHD that causes refractory angina, meaning the chest pain is persistent and not relieved by standard treatments (such as medications or lifestyle changes). Refractory angina is severe and chronic, indicating that the coronary artery disease has progressed significantly.
This form of angina typically requires more advanced medical interventions, such as surgical options (e.g., coronary artery bypass grafting or percutaneous coronary interventions like stenting).
This code is used when ASHD causes angina pectoris that doesn't fall into the categories of stable, unstable, or refractory angina. This can include variant angina or microvascular angina, which are less common forms of chest pain. Variant angina (also known as Prinzmetal's angina) occurs due to temporary spasms in the coronary arteries.
In contrast, microvascular angina occurs due to problems with the small coronary arteries that may not be detectable through traditional diagnostic methods.
This code is used when ASHD is present and the patient is experiencing angina pectoris, but the exact type of angina is not specified or cannot be determined. This might occur when the clinical details about the angina are unclear or have not yet been fully evaluated, and the healthcare provider has not defined the specific characteristics of the chest pain.
The introduction of ICD-10 has greatly enhanced the precision of cardiovascular disease coding, providing healthcare providers with a more detailed framework. This shift not only improves clinical documentation but also supports better patient care and data analysis, which are essential for effective treatment and outcomes.
As healthcare evolves, so does the need for more accurate and detailed documentation. The shift from ICD-9 to ICD-10 has revolutionized how cardiovascular diseases are coded, offering healthcare providers a more precise way to track conditions, improve patient care, and enhance treatment outcomes.
