About O09.8
O09.8 is the ICD-10-CM diagnosis code for supervision of other high risk pregnancies. It belongs to category O09 (supervision of high risk pregnancy), block O09 (supervision of high risk 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 3 subcodes must be used instead.
Within O09, choose O09.8 (other high risk pregnancies) only when documentation doesn't support a more specific option: pregnancy with history of infertility (O09.0), pregnancy with history of ectopic pregnancy (O09.1), pregnancy with other poor reproductive or obstetric history (O09.2), pregnancy with insufficient antenatal care (O09.3), pregnancy with grand multiparity (O09.4), elderly primigravida and multigravida (O09.5), young primigravida and multigravida (O09.6), due to social problems (O09.7) and 2 more.
To report this condition, pick the subcode that matches the documentation: O09.81 (technology), O09.82 (pregnancy) and O09.89 (pregnancies).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
