Valid for Submission
I31.8 is a billable diagnosis code used to specify a medical diagnosis of other specified diseases of pericardium. The code I31.8 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code I31.8 might also be used to specify conditions or terms like abnormal communication between pericardial sac and pleura, abnormal pericardiopleural communication, acquired pericardial cyst, cyst of mediastinum, deposition of fat on visceral pericardium , fistula of pericardium, etc.
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 the code I31.8:
Inclusion TermsInclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Epicardial plaques
- Focal pericardial adhesions
Index to Diseases and Injuries
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 the code I31.8 are found in the index:
- - Cyst (colloid) (mucous) (simple) (retention)
- - Diverticulum, diverticula (multiple) - K57.90
- - Pericarditis (with decompensation) (with effusion) - I31.9
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Abnormal communication between pericardial sac and pleura
- Abnormal pericardiopleural communication
- Acquired pericardial cyst
- Cyst of mediastinum
- Deposition of fat on visceral pericardium
- Fistula of pericardium
- Milk spots of pericardium
- Pericardial cyst
- Pericardial cyst along left cardiophrenic angle
- Pericarditis caused by deposits of cholesterol
- Pericarditis secondary to benign primary tumor
- Pericarditis secondary to malignant primary tumor
- Pericarditis secondary to neoplasia
- Pericarditis secondary to primary tumor
- Pericarditis secondary to tumor metastatic to pericardium
Diagnostic Related Groups - MS-DRG Mapping
|MS-DRG||MS-DRG Title||MCD||Relative Weight|
|314||OTHER CIRCULATORY SYSTEM DIAGNOSES WITH MCC||05||2.0834|
|315||OTHER CIRCULATORY SYSTEM DIAGNOSES WITH CC||05||0.9752|
|316||OTHER CIRCULATORY SYSTEM DIAGNOSES WITHOUT CC/MCC||05||0.7495|
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.
Convert I31.8 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code I31.8 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
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.
