Acute pericarditis (I30)
ICD-10 code for acute pericarditis encompasses several specific conditions involving inflammation of the pericardium, the sac surrounding the heart. These codes are used to classify different types of acute pericarditis, including idiopathic, infective, other specified forms, and unspecified cases.
The main category I30 covers general acute pericarditis, while I30.0 specifies acute nonspecific idiopathic pericarditis, also known as acute idiopathic or idiopathic recurrent pericarditis. The code I30.1 represents infective pericarditis, including bacterial types like pyogenic and pneumococcal pericarditis, viral pericarditis, and other infectious causes. Code I30.8 identifies other forms such as acute fibrinous, serofibrinous, and effusive pericarditis, often involving pericardial effusion or adhesion. Lastly, I30.9 is used for unspecified acute pericarditis cases, covering presentations like acute myopericarditis, pneumopericardium, and acute pleuropericarditis. These distinctions help ensure accurate diagnosis and treatment coding for various acute pericardial diseases.
Instructional Notations
Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- acute mediastinopericarditis
- acute myopericarditis
- acute pericardial effusion
- acute pleuropericarditis
- acute pneumopericarditis
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.
- Dressler's syndrome I24.1
- rheumatic pericarditis acute I01.0
- viral pericarditis due to Coxsackie virus B33.23
Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Pericardium
A conical fibro-serous sac surrounding the HEART and the roots of the great vessels (AORTA; VENAE CAVAE; PULMONARY ARTERY). Pericardium consists of two sacs: the outer fibrous pericardium and the inner serous pericardium. The latter consists of an outer parietal layer facing the fibrous pericardium, and an inner visceral layer (epicardium) resting next to the heart, and a pericardial cavity between these two layers.
Pneumopericardium
Presence of air or gas in the space between the heart and the PERICARDIUM. The degree of respiratory distress depends on the amount of trapped air and circulation blocked in the systemic and pulmonary veins.
