Z775 – Pharmacological management of P.I.H. and toxemia by I.V therapy
OHIP Psychiatric Code — OBSTETRICS · Schedule of Benefits
The service Z775 is for the pharmacological management of pregnancy-induced hypertension (P.I.H.) and toxemia by intravenous (I.V.) therapy. It is listed under the 'High Risk Pregnancies' subsection of the Obstetrics section.
When to Use
- Use Z775 when initiating intravenous magnesium sulfate for the management of severe pre-eclampsia or eclampsia.
- Use this code for the pharmacological management of pregnancy-induced hypertension requiring continuous intravenous antihypertensive therapy (e.g., labetalol or hydralazine infusions) in an inpatient setting.
Common Pitfalls
- Do not bill Z775 for routine intravenous fluid administration or simple hydration; it is strictly intended for the pharmacological management of PIH/toxemia.
- Avoid billing Z775 in conjunction with standard antenatal care codes, as it is a specific procedural fee for high-risk intervention.
- Ensure the diagnosis code reflects the hypertensive disorder of pregnancy, as billing Z775 without a corresponding PIH or eclampsia diagnosis will trigger an automatic rejection.
Billing Tips
- Z775 is eligible for after-hours premiums (E409, E410) if the initiation of the IV therapy meets the non-elective or emergency criteria specified in the Schedule of Benefits.
- Since Z775 is a procedural code, ensure you are not also billing a concurrent assessment code (like A007) unless a separate, distinct clinical assessment is performed and documented.
