What does the indication "Requires two codes" imply?

The indication "Requires two codes" means that it is necessary to report both a primary diagnosis and a related condition or complication to provide a complete clinical picture. Typically, in these scenarios, the rationale is to report the underlying disease or condition first. This approach ensures that the primary reason for the patient's encounter or treatment is clearly documented, followed by any additional codes that elaborate on the diagnosis.

When reporting codes in this manner, it is essential to follow the sequencing guidelines provided in the coding manuals, as it represents an accurate reflection of the patient's clinical situation. Thus, the correct interpretation of "Requires two codes" underscores the importance of establishing the hierarchy of conditions, often emphasizing the need to report the underlying disease first to give context to the patient's health status.
