Code Classification

  • Congenital malformations, deformations and chromosomal abnormalities
    (Q00-Q99)
    • Congenital malformations of the circulatory system
      (Q20-Q28)
      • Other congenital malformations of circulatory system
        (Q28)

Q28 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of other congenital malformations of circulatory system. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Other congenital malformations of circulatory system

Non-specific codes like Q28 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for other congenital malformations of circulatory system:

  • Use Q28.0 for Arteriovenous malformation of precerebral vessels - BILLABLE CODE

  • Use Q28.1 for Other malformations of precerebral vessels - BILLABLE CODE

  • Use Q28.2 for Arteriovenous malformation of cerebral vessels - BILLABLE CODE

  • Use Q28.3 for Other malformations of cerebral vessels - BILLABLE CODE

  • Use Q28.8 for Other specified congenital malformations of circulatory system - BILLABLE CODE

  • Use Q28.9 for Congenital malformation of circulatory system, unspecified - BILLABLE CODE

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.


Type 1 Excludes

Type 1 Excludes
A 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.
  • congenital aneurysm NOS Q27.8
  • congenital coronary aneurysm Q24.5
  • ruptured cerebral arteriovenous malformation I60.8
  • ruptured malformation of precerebral vessels I72.0

Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
  • congenital peripheral aneurysm Q27.8
  • congenital pulmonary aneurysm Q25.79
  • congenital retinal aneurysm Q14.1
