Information for Medical Professionals

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 - Adult. Age range is 15–124 years inclusive (e.g., senile delirium, mature cataract).

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). The diagnosis code I70.8 is grouped in the following groups for version MS-DRG V36.0 applicable from 10/01/2018 through 09/30/2019.

  • 299 - PERIPHERAL VASCULAR DISORDERS WITH MCC
  • 300 - PERIPHERAL VASCULAR DISORDERS WITH CC
  • 301 - PERIPHERAL VASCULAR DISORDERS WITHOUT CC/MCC

Information for Patients


Atherosclerosis

Also called: Arteriosclerosis

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.

ICD-10 Footnotes

General Equivalence Map Definitions
The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

  • Approximate Flag - The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
  • No Map Flag - The no map flag indicates that a code in the source system is not linked to any code in the target system.
  • Combination Flag - The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.
