2025 ICD-10-CM code J84
(Active) Effective Date: N/A Diseases of the respiratory system - Other interstitial pulmonary diseases 10 Feed
Other interstitial pulmonary diseases
Medical necessity for services related to J84 is established by documenting the signs, symptoms, and diagnostic findings consistent with interstitial lung disease. The documentation should support the need for diagnostic testing and treatment to manage the patient's condition and prevent further decline in respiratory function.
Pulmonologists are primarily responsible for diagnosing and managing patients with interstitial lung diseases. This often involves reviewing medical history, performing physical exams, ordering imaging studies (like chest X-rays and CT scans), and conducting pulmonary function tests.
In simple words: This code refers to a group of lung conditions affecting the delicate tissue between the air sacs (alveoli) of the lungs, called the interstitium, excluding those caused by drugs, external agents, or interstitial emphysema.
Other interstitial pulmonary diseases. Excludes1: drug-induced interstitial lung disorders (J70.2-J70.4) and interstitial emphysema (J98.2). Excludes2: lung diseases due to external agents (J60-J70).
Example 1: A patient presents with progressive shortness of breath and a dry cough. After ruling out other causes, the physician suspects an interstitial lung disease and uses J84 as a preliminary diagnosis before further investigation., A patient with a confirmed diagnosis of nonspecific interstitial pneumonia (NSIP), which is not otherwise specified in the ICD-10-CM, is coded as J84.17., A patient with a history of exposure to asbestos develops pulmonary fibrosis. If the fibrosis is not specifically identified as asbestosis, J84.1, Other interstitial pulmonary diseases with fibrosis, may be used as a more general code.
Documentation should clearly specify the type of interstitial lung disease suspected or diagnosed. If known, the underlying cause, location of the disease, and associated symptoms should be documented.Any diagnostic tests performed and their results, including imaging and pulmonary function tests, should also be included.
** Additional codes may be necessary to identify exposure to tobacco smoke (Z77.22, P96.81, Z87.891, Z57.31), tobacco dependence (F17.-), or tobacco use (Z72.0).J84 excludes certain conditions originating in the perinatal period (P04-P96), infectious and parasitic diseases (A00-B99), complications of pregnancy (O00-O9A), congenital malformations (Q00-Q99), endocrine/nutritional/metabolic diseases (E00-E88), injuries/poisoning (S00-T88), neoplasms (C00-D49), smoke inhalation (T59.81-), and other symptoms/signs (R00-R94).
