About O10.2

O10.2 is the ICD-10-CM diagnosis code for pre-existing hypertensive chronic kidney disease complicating pregnancy, childbirth and the puerperium. It belongs to category O10 (pre-existing hypertension complicating pregnancy, childbirth and the puerperium), block O10-O16 (edema, proteinuria and hypertensive disorders in pregnancy, childbirth and the puerperium) and chapter 15 (pregnancy, childbirth and the puerperium). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within O10 (pre-existing hypertension complicating pregnancy, childbirth and the puerperium), O10.2 is specifically for pre-existing hypertensive chronic kidney disease complicating pregnancy, childbirth and the puerperium. Related codes cover pre-existing essential hypertension complicating pregnancy, childbirth and the puerperium (O10.0), pre-existing hypertensive heart disease complicating pregnancy, childbirth and the puerperium (O10.1), pre-existing hypertensive heart and chronic kidney disease complicating pregnancy, childbirth and the puerperium (O10.3), pre-existing secondary hypertension complicating pregnancy, childbirth and the puerperium (O10.4) and unspecified pre-existing hypertension complicating pregnancy, childbirth and the puerperium (O10.9).

To report this condition, pick the subcode that matches the documentation: O10.21 (pregnancy), O10.22 (childbirth) and O10.23 (puerperium).

Use an additional code from I12 to identify the type of hypertensive chronic kidney disease.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
