What are the principal and secondary ICD-10-CM diagnosis codes for a patient with chronic bronchitis due to cigarette smoking?

• A. J41.0, F17.210
• B. I13.0, N18.4
• C. D68.00, G43.611
• D. C61, D63.0

Answer: (A)

In the context of chronic bronchitis due to cigarette smoking, the principal diagnosis code reflects the underlying condition of thoracic involvement, specifically chronic bronchitis. The code J41.0 pertains to "Simple chronic bronchitis," which is appropriate here since the condition has developed as a result of tobacco use.

The secondary diagnosis code F17.210 is used for “Nicotine dependence, cigarettes, uncomplicated.” This suggests that the patient not only has chronic bronchitis but also has a recognized dependence on cigarette smoking, which is relevant for understanding the patient's overall health status and treatment needs.

Choosing this combination of codes effectively captures both the primary lung condition and the risk factor contributing to it, providing a comprehensive picture for documentation and reimbursement purposes.
