Code Classification

  • Diseases of the circulatory system
    (I00–I99)
    • Other forms of heart disease
      (I30-I5A)
      • Other diseases of pericardium
        (I31)

I31 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 diseases of pericardium. 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 diseases of pericardium

Non-specific codes like I31 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 diseases of pericardium:

  • Use I31.0 for Chronic adhesive pericarditis - BILLABLE CODE

  • Use I31.1 for Chronic constrictive pericarditis - BILLABLE CODE

  • Use I31.2 for Hemopericardium, not elsewhere classified - BILLABLE CODE

  • I31.3 for Pericardial effusion (noninflammatory) - NON-BILLABLE CODE

  • Use I31.31 for Malignant pericardial effusion in diseases classified elsewhere - BILLABLE CODE

  • Use I31.39 for Other pericardial effusion (noninflammatory) - BILLABLE CODE

  • Use I31.4 for Cardiac tamponade - BILLABLE CODE

  • Use I31.8 for Other specified diseases of pericardium - BILLABLE CODE

  • Use I31.9 for Disease of pericardium, 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.
  • diseases of pericardium specified as rheumatic I09.2
  • postcardiotomy syndrome I97.0
  • traumatic injury to pericardium S26

Patient Education


Pericardial Disorders

The pericardium is a membrane, or sac, that surrounds your heart. It holds the heart in place and helps it work properly. Problems with the pericardium include:

  • Pericarditis - an inflammation of the sac. It can be from a virus or other infection, a heart attack, heart surgery, other medical conditions, injuries, and certain medicines.
  • Pericardial effusion - the buildup of fluid in the sac
  • Cardiac tamponade - a serious problem in which buildup of fluid in the sac causes problems with the function of the heart

Symptoms of pericardial problems include chest pain, rapid heartbeat, and difficulty breathing. Fever is a common symptom of acute pericarditis. Your doctor may use a physical exam, imaging tests, and heart tests to make a diagnosis. Treatment depends on the cause.
