Q: There’s an assumed cause and effect relationship between diabetes and peripheral artery disease, but what about coronary artery disease? Do we make the link between CAD and diabetes?
A: No. Diabetes has a causal relationship with peripheral vascular disease. There is no assumed relationship between diabetes and CAD and the conditions are coded separately.
Q: Why would you not add a code for
diabetic foot ulcer if the patient has diabetes, arteriosclerotic PVD, and a foot ulcer? Don’t you need that code for specificity?
A: When a patient has a foot ulcer with arteriosclerotic PVD and diabetes, multiple coding conventions apply. Arteriosclerosis is a specific type of angiopathy. ICD-10-CM assumes a cause and effect relationship between diabetes and angiopathy (arteriosclerosis). ICD-10-CM also assumes a link between
arteriosclerosis and the foot ulcer and tabular instructions direct the coder to use an additional code for non-pressure ulcer to describe the site and depth of the ulceration. The combination of these codes provide all the detail to know that the patient has diabetes and an ulcer. The code for diabetic foot ulcer does not provide any additional detail.

Q: I am looking for guidance regarding coding CAD with HTN. I have been linking the 2 diagnoses: I25.10, Atherosclerotic heart disease of native coronary artery without angina pectoris and I11.9, Hypertensive heart disease without heart
failure. Is this the correct way to code or should I use I25.10 & I10?
A: CAD (I25.-) is not listed as one of the linked conditions under category I11 for hypertensive heart disease. An assumed link is only made between hypertension and codes classified to I50.-, I51.4-, I51.7, I51.89, or I51.9. See the includes notes under code I11 and coding guideline I.C.9.a.1. for further clarification.
Q: Does peripheral neuropathy w/DM
code to polyneuropathy?
A: Peripheral neuropathy is damage to the nerves outside of the brain and spinal cord. When multiple peripheral nerves are affected, it is referred to as polyneuropathy. When the provider documents diabetic peripheral neuropathy, assign a code for unspecified diabetic neuropathy (e.g., E11.40, Type 2 diabetes mellitus with diabetic neuropathy, unspecified) unless the documentation indicates that multiple nerves were
affected. If, for example, the provider documented that a type 2 diabetic had peripheral neuropathy in both legs, code E11.42, Type 2 diabetes mellitus with diabetic polyneuropathy, would be assigned.
Advanced Search Help
Advanced search lets you search selected properties of the classification. You could search all properties or a selected subset only
First, you need to provide keywords in the Search Text field then check the properties that you'd like to include in the search.
The system will search for the keywords in the properties that you've checked and rank the results similar to a search engine
The results will be displayed in the Search Results pane. If the search query hits more than 200 results, then only the top 200 will be displayed.
If you provide more than one keyword, the system will search for items that have all the keywords.
Wildcards: You may also use wildcard character * . see examples below.
OR operator : It's possible to have the results that have either one or another keyword. Please see the example 4.
Examples:
1. Search Text: diabetes {finds all that have the word "diabetes" in the searched fields}
2. Search Text: diabet* {finds all that have a word that start with "diabet" }
3. Search Text: diabet* mellitus {finds all that have a word that starts with "diabet" and also contains the word "mellitus"}
4. Search Text: tubercul* (lung OR larynx) { finds all that have a word that starts with "tubercul" and than has either lung OR larynx in it
Search Results
After the search the results are displayed at the lower right area of the screen. Here the porgram lists the titles of the ICD categories in which your search keywords are found.
Clicking on any result will take you to that category
You may close the advanced search window by clicking the X at the top left corner of the window.
The search results pane can be resized by dragging the horizontal line above it
