An inpatient record documents type 2 diabetes mellitus with diabetic chronic kidney disease, and ICD-10-CM provides a combination code that fully captures both. What is the preferred coding approach?
Select an answer to reveal the explanation.
Short Explanation
When the book hands you one combination code that already says “diabetes with diabetic CKD,” do not build a DIY sandwich out of separate pieces. One solid combo beats two half-codes that say the same thing less cleanly.
Full Explanation
ICD-10-CM instructional guidance directs coders to use a combination code when it fully identifies the documented diagnostic statement. For type 2 diabetes with diabetic chronic kidney disease, the appropriate combination code family is preferred over separately coding diabetes and CKD as unrelated conditions when the combination fully captures what is documented. Additional codes may still be needed for stage or other required details when instructional notes call for them.
