Complications & Comorbid Conditions (CC/MCC) Rules for I74.3
When I74.3 is used as a secondary diagnostic code, the patient's visit may be considered to have Complications & Comorbid Conditions (CC) or Major Complications & Comorbid Conditions (MCC).
Exclusions apply. When the primary diagnostic code is is in the exclusion list, the patient visit CC/MCC does not qualify for a CC or MCC.
CC/MCC grouping rules are adjusted each year, so check the rules for the fiscal year of the patient's discharge date.
DRG Mapping Rules for I74.3
Diagnostic codes are the first step in the DRG mapping process.
The patient's primary diagnostic code is the most important. Assuming the patient's primary diagnostic code is I74.3, look in the list below to see which MDC's "Assignment of Diagnosis Codes" is first. That is the MDC that the patient will be grouped into.
From there, check the subsections of the MDC listed. The patient will be mapped into the first subsection for which the treatment performed on the patient meet the listed requirements of that subsection.
DRG grouping rules are adjusted each year, so make sure to check the rules for the fiscal year of the patient's discharge date.
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
