Valid for Submission
I30.9 is a billable diagnosis code used to specify a medical diagnosis of acute pericarditis, unspecified. The code I30.9 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 I30.9 might also be used to specify conditions or terms like acute bloody pericarditis, acute mediastinitis, acute mediastinopericarditis, acute myopericarditis, acute pericardial effusion , acute pericarditis, etc.
Unspecified diagnosis codes like I30.9 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.

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.
