What information is required to accurately code PVD due to diabetes in ICD-10-CM?

To accurately code for peripheral vascular disease (PVD) due to diabetes in ICD-10-CM, it is crucial to determine whether the patient has gangrene. This information is vital because the presence of gangrene can significantly impact the specific codes used. In ICD-10-CM, there are distinct codes that represent diabetic gangrene as opposed to cases of peripheral vascular disease without gangrene. Accurately identifying gangrene allows coders to assign the correct code, ensuring that the documentation reflects the severity and complexity of the patient's condition. This level of detail is critical for both clinical and reimbursement purposes.

Focusing exclusively on the presence or absence of gangrene provides the most precise information necessary for coding PVD due to diabetes. Other factors like blood sugar levels, the type of diabetes, and the duration of diabetes do not directly influence the specific coding of PVD related to diabetes and do not provide the granularity needed for proper code assignment in this context.
