ICD-10 Code A34 – Obstetrical Tetanus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A34 – Obstetrical tetanus
What it is
A34 identifies tetanus occurring in relation to pregnancy, childbirth, or the postpartum period. Use it when documentation specifically states obstetrical tetanus.
Clinical signs
Clinical features vary; refer to documentation. Tetanus commonly involves muscle rigidity, painful spasms, and difficulty opening the mouth, but the obstetrical context must be clearly stated.
When to use this code
Use A34 when the record links tetanus to an obstetrical setting, such as during pregnancy, delivery, or after childbirth. It supports coding when the provider documents obstetrical tetanus explicitly. If the note only says tetanus without an obstetric link, check documentation.
Do not use for
Do not use this code for neonatal tetanus or tetanus unrelated to pregnancy or childbirth. If the chart does not identify an obstetrical context, this code is not supported.
Coding tip
Confirm the obstetrical association in the provider’s diagnosis statement before assigning A34.
