Question: I need help locating the iCD-10 codes for use of high-risk medication during pregnancy. What should I report?

Answer: Since the drug monitoring is impacting the pregnancy, you would use a supervision of high risk code for your primary diagnosis and a Z code to indicate which drug (if listed) as your secondary code.
Look to O09.89 (Supervision of other high risk pregnancies) as your primary. Code O35.5XX (Maternal care for [suspected] damage to fetus by drugs) is also an option, but most payers think this means drug addiction.
For the Z code, if no other entry specifically states the medication you are looking for, try the “generic” code of Z79.899 (Other long term [current] drug therapy).
