O26.84Uterine size-date discrepancy complicating pregnancy

O26.84 is the ICD-10-CM diagnosis code for uterine size-date discrepancy complicating pregnancy. It belongs to category O26 (maternal care for other conditions predominantly related to pregnancy), block O20-O29 (other maternal disorders predominantly related to pregnancy) and chapter 15 (pregnancy, childbirth and the puerperium). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

Within O26.8 (other specified pregnancy related conditions), O26.84 is specifically for uterine size-date discrepancy complicating pregnancy. Related codes cover pregnancy related exhaustion and fatigue (O26.81), pregnancy related peripheral neuritis (O26.82), pregnancy related renal disease (O26.83), Spotting complicating pregnancy (O26.85), pruritic urticarial papules and plaques of pregnancy (PUPPP) (O26.86), cervical shortening (O26.87) and other specified pregnancy related conditions (O26.89).

To report this condition, pick the subcode that matches the documentation: O26.841 (trimester), O26.842 (trimester), O26.843 (trimester) and O26.849 (trimester).

Don't report O26.84 together with the conditions in its Excludes1 note: encounter for suspected problem with fetal growth ruled out (Z03.74).

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