How is the sequencing of diabetes coded as a secondary manifestation determined?

The correct choice is based on the coding guidelines provided in the Tabular List of the ICD-10-CM coding system. When it comes to coding diabetes and its secondary manifestations, the Tabular List contains specific instructions that detail how to properly sequence these codes.

In the case of diabetes, it’s essential to first assign the main diagnosis, which typically identifies the underlying cause of the patient's condition. Following this, additional codes that represent secondary manifestations—such as diabetic retinopathy or neuropathy—should be sequenced according to the guidelines found in the Tabular List. This ensures that the primary condition is properly highlighted, while also giving appropriate attention to the complications arising from it.

The coding process must adhere to these official instructions to ensure compliance with coding standards and accurate reimbursement processes. Each manifestation may have a particular coding requirement, typically detailed in the guidelines, which must be followed to provide a clear and accurate representation of the patient's health status.
