Dilated vs Ischemic Cardiomyopathy

Hi! From my understanding, ischemic cm is a type of dilated cardiomyopathy. When I look up dilated CM in the encoder, it asks if the pt also has ischemic cardiomyopathy, and both codes come up (I420, I255). Is this just a encoder issue? The last coding clinic on this issue is from 2013, before ICD 10, but we haven't found a coding clinic to supercede this one. Can anyone speak on if we only code ischemic type or if we also include the dilated CM?

Coding Clinic, Fourth Quarter 2013 Page: 102
New codes contained in this issue effective with discharges October1, 2013. Other coding advice or code assignments contained in this issue effective with discharges October 21, 2013.
 
Question:
 
What is the correct ICD-9-CM code assignment when dilated and ischemic cardiomyopathy are both documented by the provider in the medical record?
 
Answer:
 
Assign code 414.8, Other specified forms of chronic ischemic heart disease, for dilated and ischemic cardiomyopathy. The underlying cause is the ischemic cardiomyopathy.

    Looking in a code book...the entire I42 category has I25.5 as an excludes 2, meaning they can be reported together if both are present and clinically valid.
