2025 ICD-10-CM code I30.8

Other forms of acute pericarditis.

Follow all current ICD-10-CM coding guidelines published by CMS for proper selection and documentation of this code.Ensure that the code reflects the clinical documentation accurately.

Modifiers may apply depending on the circumstances of the encounter.Consult the appropriate modifier guidelines.For example, a modifier may be used to indicate a bilateral condition or a significant complication.

Medical necessity for coding I30.8 is established by the presence of clinical findings consistent with acute pericarditis, supported by objective diagnostic testing. The severity of symptoms and potential complications justify the diagnosis and subsequent treatment.

The clinical responsibility for this code falls upon the physician diagnosing and managing the patient's acute pericarditis. This includes obtaining a thorough history, performing a physical examination, ordering relevant diagnostic tests (such as electrocardiogram (ECG), echocardiogram, and chest X-ray), and determining the appropriate treatment plan which may involve medication, pericardiocentesis, or other interventions depending on the severity and cause.

IMPORTANT:Consider I30.9 (Acute pericarditis, unspecified) if the specific type of acute pericarditis is unknown or cannot be determined.Also review codes for specific causes of pericarditis (viral, bacterial, etc.) if known.

In simple words: This code describes an inflammation of the sac around the heart (pericardium) that doesn't fall into other specific types of heart inflammation.It can cause chest pain and fever.

This code classifies acute pericarditis that doesn't fit into other specified categories of acute pericarditis.Acute pericarditis is inflammation of the pericardium, the sac surrounding the heart. This inflammation can cause chest pain, fever, and other symptoms.The "other forms" designation encompasses various etiologies and presentations not explicitly detailed elsewhere in the ICD-10-CM classification.

Example 1: A 60-year-old male presents to the emergency room with acute onset of severe chest pain radiating to the back. ECG reveals diffuse ST-segment elevations.Echocardiogram confirms a large pericardial effusion.The diagnosis of acute pericarditis is made, but the underlying cause remains undetermined after extensive testing.I30.8 is coded., A 35-year-old female experiences sudden onset of sharp chest pain worsened by deep breaths.Physical exam reveals a pericardial friction rub.ECG demonstrates diffuse ST-segment elevation and PR-segment depression. After additional testing, the etiology remains unclear. I30.8 is the appropriate code., A 72-year-old male with a history of myocardial infarction presents with worsening chest pain, fever, and shortness of breath.ECG and echocardiogram show signs of pericarditis. Further investigation reveals no specific infectious or non-infectious cause; I30.8 is selected.

Detailed history and physical examination, including description of the chest pain (location, radiation, character, timing, aggravating/relieving factors).ECG findings, echocardiographic findings (pericardial effusion, wall motion abnormalities), results of any other relevant diagnostic tests (chest X-ray, blood tests including inflammatory markers).Treatment plan and response to treatment.

** Always ensure that the underlying etiology of the acute pericarditis is investigated and documented if possible.If a specific cause is identified (e.g., viral, bacterial, idiopathic), that specific etiology should be coded in addition to I30.8.
