What ICD-10-CM code is reported for spontaneous pneumothorax?

The appropriate ICD-10-CM code for spontaneous pneumothorax is J93.83. This code specifically refers to a spontaneous pneumothorax, which occurs without any obvious cause or underlying lung disease, often referred to as a primary spontaneous pneumothorax.

In the context of coding, it is essential to differentiate between various types of pneumothorax. The other codes listed pertain to different classifications. For example, J90.00 relates to unspecified pleural effusion, while J93.81 refers to tension pneumothorax, which is a different clinical situation involving trapped air causing increased pressure. J94.9 is a general code for other specified diseases of the pleura but does not specify pneumothorax. Understanding these distinctions helps ensure accurate and precise coding for patient diagnoses.
