Respiratory System Diagnosis Codes

Respiratory codes cover conditions from the common cold to chronic diseases like COPD and asthma. This chapter also includes pneumonia, bronchitis, and influenza codes. Respiratory conditions are among the top reasons for doctor visits and hospitalizations.

About This Chapter

Chapter 10 of the ICD-10-CM classification covers diseases of the respiratory system, spanning codes J00-J99. These codes are used by healthcare providers to document diagnoses in your electronic health record (EHR), on insurance claims, and on medical bills.

Why this matters: If you see a code starting with J on your medical bill or health records, it likely falls in this chapter. Understanding what chapter your code belongs to can help you make sense of your diagnosis and ask better questions at your next appointment.
