What This Code Means

A secondary form of diabetes with kidney complications other than nephropathy or chronic kidney disease.

Coding Tips

•Use this code for diabetic kidney complications not captured by E13.21 or E13.22
•Document the specific kidney complication in the medical record for clarity

Clinical Significance

E13.29 covers diabetic kidney complications in other specified diabetes that are neither standard nephropathy nor chronic kidney disease. This includes conditions such as renal tubular degeneration, Kimmelstiel-Wilson disease when specifically documented, or other diabetes-related renal pathology that does not fit the more common nephropathy or chronic kidney disease classification.

Documentation Requirements

✓The provider must document the secondary diabetes type, the underlying cause, and the specific kidney complication.
✓The nature of the renal complication should be clearly described to justify why neither E13.21 (nephropathy) nor E13.22 (chronic kidney disease) is appropriate.

Commonly Confused Codes

E13.21 (diabetic nephropathy) for general kidney damage from diabetes E13.22 (diabetic chronic kidney disease) when chronic kidney disease staging is available E11.29 (type 2 diabetes with other kidney complication) when diabetes is type 2.
