I71.8 is a billable ICD-10 code used to specify a medical diagnosis of aortic aneurysm of unspecified site, ruptured. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.

Unspecified diagnosis codes like I71.8 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.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

Rupture of aorta
Ruptured aortic aneurysm

Clinical Information

Ruptured Aortic Aneurysm-. a ruptured aneurysm located in the wall of the aorta.

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to this diagnosis code:

Inclusion Terms

Rupture of aorta NOS

Index to Diseases and Injuries References

The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for this diagnosis code are found in the injuries and diseases index:

- Aneurysm (anastomotic) (artery) (cirsoid) (diffuse) (false) (fusiform) (multiple) (saccular) - I72.9
- - aorta, aortic (nonsyphilitic) - I71.9
  - - arteriosclerotic - I71.9
    - - ruptured - I71.8
  - - descending - I71.9
    - - ruptured - I71.8
  - - ruptured - I71.8
- - cylindroid (aorta) - I71.9
  - - ruptured - I71.8

- Rupture, ruptured
- - aorta, aortic - I71.8
  - - descending - I71.8

Diagnostic Related Groups - MS-DRG Mapping

The is diagnosis code is grouped in the following groups for version MS-DRG V40.0 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 10/01/2022 through 09/30/2023.

MS-DRG	MS-DRG Title	MCD	Relative Weight
299	PERIPHERAL VASCULAR DISORDERS WITH MCC	05	1.538
300	PERIPHERAL VASCULAR DISORDERS WITH CC	05	1.0311
301	PERIPHERAL VASCULAR DISORDERS WITHOUT CC/MCC	05	0.7162

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.

Patient Education

Aortic Aneurysm

An aneurysm is a bulge or "ballooning" in the wall of an artery. Arteries are blood vessels that carry oxygen-rich blood from the heart to other parts of the body. If an aneurysm grows large, it can burst and cause dangerous bleeding or even death.

Most aneurysms are in the aorta, the main artery that runs from the heart through the chest and abdomen.

There are two types of aortic aneurysm:

Thoracic aortic aneurysms (TAA) - these occur in the part of the aorta running through the chest
Abdominal aortic aneurysms (AAA) - these occur in the part of the aorta running through the abdomen

Most aneurysms are found during tests done for other reasons. Some people are at high risk for aneurysms. It is important for them to get screening, because aneurysms can develop and become large before causing any symptoms. Screening is recommended for people between the ages of 65 and 75 if they have a family history, or if they are men who have smoked. Doctors use imaging tests to find aneurysms. Medicines and surgery are the two main treatments.
