ICD-10 Code I25.10

Atherosclerotic heart disease of native coronary artery without angina pectoris

What is the code I25.10?

ICD-10-CM code I25.10 denotes “atherosclerotic heart disease of native coronary artery without angina pectoris.” This code is part of the larger ICD-10 classification system used by healthcare professionals for documenting and billing. I25.10 specifically identifies atherosclerosis within the coronary arteries that has not yet resulted in angina, a symptom characterized by chest pain or discomfort due to reduced blood flow to the heart.

Detailed description of I25.10

The ICD-10 code I25.10 describes atherosclerotic heart disease of native coronary artery without angina pectoris. Atherosclerosis refers to the buildup of fats, cholesterol, and other substances (plaques) in and on the artery walls, which can restrict blood flow. When these plaques occur in the coronary arteries, they can lead to coronary artery disease. The term "native coronary artery" indicates that the condition affects the patient's original coronary arteries, not grafts or transplanted vessels. The absence of angina pectoris means that, despite the presence of atherosclerosis, the patient does not experience the chest pain or discomfort typically associated with reduced oxygen supply to the heart muscle.

Symptoms commonly associated with I25.10

While I25.10 specifically denotes the absence of angina pectoris, patients with atherosclerotic heart disease may still experience other symptoms related to the condition, such as:

  • Shortness of breath
  • Fatigue
  • Palpitations
  • Dizziness or lightheadedness
  • Swelling in the hands, ankles, or feet
  • Unusual sweating
  • Nausea

It is important to note that these symptoms can vary widely and may not be present in all patients with atherosclerotic heart disease.

Related and similar ICD-10 codes

Several ICD-10 codes are related to or similar to I25.10, each specifying different aspects or conditions associated with coronary artery disease, including:

  • I25.11: Atherosclerotic heart disease of native coronary artery with angina pectoris
  • I25.2: Old myocardial infarction
  • I25.5: Ischemic cardiomyopathy
  • I25.6: Silent myocardial ischemia
  • I25.700: Atherosclerosis of coronary artery bypass graft(s), unspecified, with unstable angina pectoris
  • I25.701: Atherosclerosis of coronary artery bypass graft(s), unspecified, with angina pectoris with documented spasm

Appropriate usage of I25.10 for billing

Use ICD-10 code I25.10 when a patient has been diagnosed with atherosclerotic heart disease of the native coronary arteries without the presence of angina pectoris. This code can also be assigned as the default code for documentation of coronary artery disease when the medical record lacks additional specificity. Accurate coding helps ensure proper reimbursement.

Instructional notes and/or guidelines with I25.10

When using the I25.10 code for billing and coding, healthcare providers should adhere to the following guidelines:

  • Ensure documentation of the patient's diagnosis of atherosclerotic heart disease in the patient's medical record.
  • Use the code only when the condition affects the native coronary arteries, not grafts or transplanted vessels.
  • Avoid using I25.10 if the patient exhibits symptoms of angina pectoris, in which case a different code, such as I25.11, should be used.
  • Other terms that are coded to I25.10 are:
    • Atherosclerotic heart disease not otherwise specified
    • Atherosclerotic cardiovascular disease
    • Coronary (artery) atheroma
    • Coronary (artery) atherosclerosis
    • Coronary (artery) disease
    • Coronary (artery) sclerosis
  • Use additional codes, if applicable, to identify:
    • Coronary atherosclerosis due to calcified coronary lesion (I25.84)
    • Coronary atherosclerosis due to lipid rich plaque (I25.83)

Common pitfalls in coding with I25.10

Several common pitfalls can occur when coding with I25.10, including:

  • Using I25.10 for conditions involving angina pectoris, which should be coded separately.
  • Applying the code to non-native coronary arteries, such as grafts or transplanted vessels.

Key resources for I25.10 coding

Healthcare providers and medical coders can refer to several key resources for accurate coding with I25.10, including:

These resources provide detailed instructions and updates on coding standards and practices.

Conclusion

Using ICD-10 code I25.10 accurately is important for proper diagnosis documentation, billing, and reimbursement. By understanding the detailed description, associated symptoms, related codes, and appropriate usage guidelines, healthcare providers can help ensure precise coding practices. Avoiding common pitfalls and using key resources will further enhance the accuracy and efficiency of medical coding for atherosclerotic heart disease of native coronary artery without angina pectoris.
