ICD code for PIH after delivery or post partum

We are having trouble coming up with a diagnosis for pregnancy induced hypertension but for a patient that has already delivered. For example, patient is still in the hospital after delivery and is still being treated for PIH.
ICD 10 has a code for PIH (O-code) but that does not seem to fit as the patient has already delivered, the code asks to specify trimester and weeks.
The I10 code does not seem accurate either as the hypertension is not unspecified (we known it was pregnancy induced).
Has anyone else run across this diagnosis issue and what code do you use?
Thank you!
