Pregnancy supervision ICD-10 codes
Start with the primary code, then move to a more specific related code when the documentation supports it.
Z34.90 | Encounter for supervision of normal pregnancy, unspecified, unspecified trimester | ICD-10-CM |
Z34.91 | Encounter for supervision of normal pregnancy, unspecified, first trimester | ICD-10-CM |
Z34.92 | Encounter for supervision of normal pregnancy, unspecified, second trimester | ICD-10-CM |
Z34.93 | Encounter for supervision of normal pregnancy, unspecified, third trimester | ICD-10-CM |
O09.90 | Supervision of high risk pregnancy, unspecified, unspecified trimester | ICD-10-CM |
Z3A.20 | 20 weeks gestation of pregnancy | ICD-10-CM |
Use Z34.- for routine normal pregnancy supervision, with trimester specificity when documented. Use O09.- for high-risk pregnancy supervision. Add the appropriate Z3A.- weeks-of-gestation code when documented and required.
“Routine antenatal visit at 20 weeks gestation. No bleeding, contractions, headache, or visual symptoms. Fundal height appropriate, fetal movements present. Assessment: normal second-trimester pregnancy supervision.”
Paste a note or record audio. Notat’s FactsContext™ engine extracts the raw clinical facts first, then suggests codes from that context so you can inspect the evidence before using anything.

FactsContext extracts clinical facts first: diagnoses, symptoms, negatives, findings, test results, medications, and plan decisions.
The clinician can read and reuse the extracted medical context directly, independent of the generated note.

FAQ
When do I use Z34.92?
Use Z34.92 for routine supervision of a normal pregnancy in the second trimester when no high-risk condition or complication is being coded as the primary reason.
When does pregnancy supervision become high risk?
When the clinician documents high-risk pregnancy supervision or a high-risk condition driving the visit, coding usually moves from Z34.- to O09.- or a complication code.
Can AI capture trimester and gestational age?
Notat extracts gestational age, trimester, risk status, symptoms, and assessment as clinical facts, then suggests the supported pregnancy-supervision codes with evidence.
