Tabular List of Diseases and Injuries
The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.
Code First
Code FirstCertain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
- underlying disease
Type 1 Excludes
Type 1 ExcludesA type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- syphilitic aneurysm A52.01
Code Edits
The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10-CM Code Edits are applicable to this code:
- Manifestation diagnoses - Manifestation codes describe the manifestation of an underlying disease, not the disease itself, and therefore should not be used as a principal diagnosis.
Convert I79.0 to ICD-9-CM
- ICD-9-CM Code: 441.9 - Aortic aneurysm NOS
Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.
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.
