I10 is a valid ICD-10-CM diagnosis code meaning 'Essential (primary) hypertension'.
These diag codes should never be used at the same time as I10 because these conditions cannot occur together:
These conditions are is not covered by I10:
A patient may have both conditions at the same time, but both conditions must be coded separately.
I10 is not a CC or MCC.
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 I10, 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.
