Attached are the ICD-10-CM diagnostic codes for ACS conditions.
Where only two digits are listed, all diagnoses at the 3rd, 4th,
and 5th digit should be included (e.g., asthma is listed as J45,
but you should include J45.20, J45.21, J45.22…J45.991,
J45.998). Where only three digits are listed, all diagnoses at the
4th, and 5th digit should also be included etc., etc.
All diagnoses refer to principal diagnosis, unless otherwise
specified (e.g., dehydration, iron deficiency, nutritional
deficiency, etc.). Where exclusions of surgical patients are
specified (e.g., hypertension), search all procedure fields for
excluded procedures.
Please do not hesitate to contact us if you have any questions.
