The following non-standard ICD10 Diagnoses we customized/added have been added to encode specific diagnostic details that ICD10 doesn't account for. Pages would generally be added to this page using Template:ICD10 nonstandard code.

Our tracking of this list is not complete. Any codes that have a collection start date after the start of ICD10 collection may not have been annotated for this and should be reviewed for this when relevant.

ICD10-CA specific Codes

In general here we're using the ICD10#ICD-10-CA (Canadian) version but in some cases we have borrowed codes that are from the US customization.


ICD10 CM specific Codes

These are codes that follow the American ICD10 CM listing and are different from the WHO listing.


Codes our program added

  • U00-U49 - Provisional codes for temporary assignment by World Health Organization of new diseases of uncertain etiology
  • U50-U99 - Provisional codes for research and temporary assignment in Canada

List of our Custom Codes

Total List of codes in the contingency range

These should all be already addressed above, think of this as a contingency check in case we forgot to specifically address one.


Effect on other systems that use ranges of codes in definitions

APACHE Acute Dxs in ICD10 codes, APACHE Comorbidities in ICD10 codes, Charlson Comorbidities in ICD10 codes and ICD10 blocks rely on ranges of codes. Some of the diagnoses listed above might be coded instead of other diagnoses that would have been in the relevant ranges, and therefore prevent inclusion in one of these schemes.

The instructions for Adding a new ICD10 code include directions to consider these implications.
