2022 ICD-10-CM Code I70.90
Unspecified atherosclerosis
Valid for Submission
| ICD-10: | I70.90 |
| Short Description: | Unspecified atherosclerosis |
| Long Description: | Unspecified atherosclerosis |
Code Classification
I70.90 is a billable diagnosis code used to specify a medical diagnosis of unspecified atherosclerosis. The code I70.90 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code I70.90 might also be used to specify conditions or terms like abnormal diffuse intimal thickening of artery, acute occlusion of artery, arteriosclerosis obliterans, arteriosclerotic vascular disease, arteriovascular degeneration , asymptomatic occlusion of artery, etc.
The code I70.90 is applicable to adult patients aged 15 through 124 years inclusive. It is clinically and virtually impossible to use this code on a patient outside the stated age range.
Unspecified diagnosis codes like I70.90 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Code Edits
The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10 Code Edits are applicable to this code:
- Adult diagnoses - The Medicare Code Editor detects inconsistencies in adult cases by checking a patient's age and any diagnosis on the patient's record. The adult code edits apply to patients age range is 15–124 years inclusive (e.g., senile delirium, mature cataract).

Clinical Information
- INTRACRANIAL ARTERIOSCLEROSIS-. vascular diseases characterized by thickening and hardening of the walls of arteries inside the skull. there are three subtypes: 1 atherosclerosis with fatty deposits in the arterial intima; 2 monckeberg's sclerosis with calcium deposits in the media and 3 arteriolosclerosis involving the small caliber arteries. clinical signs include headache; confusion; transient blindness amaurosis fugax; speech impairment; and hemiparesis.
- CORONARY ARTERY DISEASE-. pathological processes of coronary arteries that may derive from a congenital abnormality atherosclerotic or non atherosclerotic cause.
- ATHEROSCLEROSIS-. a thickening and loss of elasticity of the walls of arteries that occurs with formation of atherosclerotic plaques within the arterial intima.
Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code I70.90 is grouped in the following groups for version MS-DRG V39.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2021 through 09/30/2022.
| MS-DRG | MS-DRG Title | MCD | Relative Weight |
|---|---|---|---|
| 299 | PERIPHERAL VASCULAR DISORDERS WITH MCC | 05 | 1.5314 |
| 300 | PERIPHERAL VASCULAR DISORDERS WITH CC | 05 | 1.0422 |
| 301 | PERIPHERAL VASCULAR DISORDERS WITHOUT CC/MCC | 05 | 0.7425 |
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.
Convert I70.90 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code I70.90 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.

Information for Patients
Atherosclerosis
Atherosclerosis is a disease in which plaque builds up inside your arteries. Plaque is a sticky substance made up of fat, cholesterol, calcium, and other substances found in the blood. Over time, plaque hardens and narrows your arteries. That limits the flow of oxygen-rich blood to your body.
Atherosclerosis can lead to serious problems, including
- Coronary artery disease. These arteries supply blood to your heart. When they are blocked, you can suffer angina or a heart attack.
- Carotid artery disease. These arteries supply blood to your brain. When they are blocked you can suffer a stroke.
- Peripheral arterial disease. These arteries are in your arms, legs and pelvis. When they are blocked, you can suffer from numbness, pain and sometimes infections.
Atherosclerosis usually doesn't cause symptoms until it severely narrows or totally blocks an artery. Many people don't know they have it until they have a medical emergency.
A physical exam, imaging, and other diagnostic tests can tell if you have it. Medicines can slow the progress of plaque buildup. Your doctor may also recommend procedures such as angioplasty to open the arteries, or surgery on the coronary or carotid arteries. Lifestyle changes can also help. These include following a healthy diet, getting regular exercise, maintaining a healthy weight, quitting smoking, and managing stress.
