ICD10 collection

This article provides general information about collecting and coding a ICD10 Diagnosis.

Collection Instructions

To find an ICD10 Diagnosis to code, try the following:

search wiki for the dx name
search wiki for a different name for the diagnosis, or an acronym
find a related article and check it's
- alternate diagnosis links
- related articles links
- categories
if you can't find a code on our wiki for the term you are looking for, check one of the following:
- An excellent source is the website https://www.icd10data.com/ICD10CM/Codes
- Wikipedia has ICD-10 codes listed in the upper right hand corner and also in the infobox at the bottom of the page for most diagnoses
When you find what you are looking for, make sure you add the search term that you could not find to the page on our wiki so the next person will find it by that name, and so we can code it consistently and the statistician can use it consistently.

Some diagnoses are coded as several lines of data as combined ICD10 codes.

To enter one line of data,

If not already there, in Patient Viewer, click the ICD10 tab
click the dropdown for type and chose one of the following:
- Admit - Admit Diagnosis
  - primary checkbox is the far left column. You must check ONE only as the Primary Admit Diagnosis, primary being the most responsible reason for admission to your specific unit.
    - If the Primary Admit Diagnosis is not a single ICD10 code but a case of combined ICD10 codes, check ONE which is the main diagnosis in the group.
    - Only ONE checked box must appear for each patient from the LOWEST priority number used.
  - Date of occurrence not allowed
- Acquired - Acquired Diagnosis / Complication
  - Date of occurrence required
- Comorbid - Comorbid Diagnosis
  - Date of occurrence not allowed
if you know the diagnosis name verbatim, you can click into the DX field and start typing; else, use the ICD10 Chooser form

	dx codes in CCMDB.mdb are not found via "?" button if words are in brackets. Could not replicate, contacted Laura for more details.

I noticed when using the search function utilizing the "?" button, if a word is in brackets it will not display. For example, I put in "thyrotoxicosis" and it did not display because that word is in brackets for Thyroid storm. It would be nice if all of the bracketed words could also be searched. When I do the search on the wiki list, the bracketed words are searchable. This only applies to the list in CCMDB. --LKolesar 12:54, 2019 January 24 (CST)
- I just tried to test this. Clicked on the "?" button and searched for "regur" to hopefully get Mitral valve insufficiency (regurgitation). It found it. Same when I searched for thyrotoxicosis, it found Thyroid storm or crisis (severe thyrotoxicosis). So I wonder what you are doing differently... Ttenbergen 13:26, 2019 February 1 (CST)

if you are entering an Acquired Diagnosis / Complication, enter the Dx_Date
- if the date is unavailable, check the Dx Date unknown checkbox.
- you can use the *, +, - buttons to set the date
enter a Dx_Priority
- For Admit, assign a number in order of importance (the lowest being the worst).
- For Acquired, just assign a number for each code with no order of importance.
- For Comorbid, just assign a number for each code with no order of importance.
- Use the same number to group together combined ICD10 codes.
- Use one number order set for each:
  - Admit Dx (1 to n)
  - Acquired Dx (restart at 1 to n)
  - Comorbid (restart at 1 to n)

We will NOT code things as suspected until we have confirmation (however that's done clinically) that it's actually present.
Instead, code the manifestation:
- Which could be a symptom, a sign, a diagnostic test abnormality
- For a tumor which isn't known yet whether it's malignant or not, then you can use (as long as it remains unknown) Neoplasm of uncertain behavior (i.e. not clear if benign or malignant), NOS
  - If you know that there is a tumor in an organ, but don't yet know whether or not it's malignant, then code the clinical manifestation (as above) AND Neoplasm of uncertain behavior (i.e. not clear if benign or malignant), NOS
If the patient dies or otherwise leaves your unit before you figure out the true cause/diagnosis, then don't try to go beyond coding the manifestation(s).
