2025 ICD-10-CM code I30.0
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Diseases of the circulatory system - Other forms of heart disease Diseases of the circulatory system (I00-I99) Feed
Acute nonspecific idiopathic pericarditis is an inflammation of the pericardium (the sac surrounding the heart) with an unknown cause.
Modifiers may be applicable depending on the circumstances of service. Consult the most current CPT and HCPCS modifier guidelines.
Medical necessity for diagnosis and treatment is established by the presence of symptoms suggestive of pericarditis, confirmed by diagnostic testing (ECG and echocardiogram).Treatment is medically necessary to alleviate symptoms, prevent complications such as cardiac tamponade, and address potential underlying conditions.
Diagnosis and management of acute nonspecific idiopathic pericarditis typically involves taking a thorough patient history, physical examination, performing diagnostic tests (ECG, echocardiogram), and initiating appropriate treatment strategies.
In simple words: This code means you have an inflammation of the sac around your heart. The cause of the inflammation is unknown.You may have chest pain, fever, or other symptoms.
Acute nonspecific idiopathic pericarditis is characterized by inflammation of the pericardium, the sac-like membrane enclosing the heart.The etiology is unknown, distinguishing it from pericarditis caused by infection, trauma, or autoimmune disorders.Clinical presentation may include chest pain, fever, and pericardial effusion (fluid accumulation around the heart).Diagnosis relies on clinical findings, electrocardiogram (ECG) changes, and echocardiography. Treatment focuses on managing symptoms and underlying causes if identified.
Example 1: A 45-year-old patient presents to the emergency room with sudden onset of sharp chest pain that worsens with deep breaths.ECG reveals diffuse ST-segment elevation. Echocardiogram shows a small pericardial effusion.I30.0 is coded, along with codes for chest pain and pericardial effusion., A 60-year-old patient experiences substernal chest discomfort and low-grade fever for several days.ECG shows electrical alternans.Echocardiogram confirms pericardial effusion. I30.0 is used in conjunction with codes for pericardial effusion and fever., A 28-year-old patient presents with pleuritic chest pain, fever, and tachycardia.ECG shows PR depression. Echocardiogram shows no pericardial effusion but confirms pericardial inflammation. I30.0 is coded along with codes for fever and chest pain. Further investigation may be needed to rule out other causes.
Detailed history of present illness, including onset, character, and location of chest pain;results of physical examination; ECG findings; echocardiogram results (including images and measurements of pericardial effusion);laboratory findings (CBC, inflammatory markers); and any imaging results. Documentation should support the diagnosis of acute pericarditis and rule out other potential causes.
