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 I77.810 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


Vascular Diseases

The vascular system is the body's network of blood vessels. It includes the arteries, veins and capillaries that carry blood to and from the heart. Problems of the vascular system are common and can be serious. Arteries can become thick and stiff, a problem called atherosclerosis. Blood clots can clog vessels and block blood flow to the heart or brain. Weakened blood vessels can burst, causing bleeding inside the body.

You are more likely to have vascular disease as you get older. Other factors that make vascular disease more likely include

  • Family history of vascular or heart diseases
  • Pregnancy
  • Illness or injury
  • Long periods of sitting or standing still
  • Any condition that affects the heart and blood vessels, such as diabetes or high cholesterol
  • Smoking
  • Obesity

Losing weight, eating healthy foods, being active and not smoking can help vascular disease. Other treatments include medicines and surgery.

  • Aortic arch syndrome (Medical Encyclopedia)
  • Arterial embolism (Medical Encyclopedia)
  • Arteriogram (Medical Encyclopedia)
  • Cerebral angiography (Medical Encyclopedia)
  • Duplex ultrasound (Medical Encyclopedia)
  • Venous insufficiency (Medical Encyclopedia)
  • Venous ulcers -- self-care (Medical Encyclopedia)

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.
