Supervision of pregnancy w grand multiparity, unsp trimester

This code signifies the medical oversight of a pregnancy in a patient who has previously had five or more viable pregnancies (grand multipara). It indicates that the specific trimester of the current pregnancy is not documented or otherwise unspecified. This supervision is provided due to the inherent risks associated with grand multiparity.

Use this code when a grand multiparous patient is receiving routine or specialized antenatal care, and the medical record does not specify the trimester. Documentation should clearly indicate the patient's grand multiparous status (e.g., "G6P5" or "gravida 6, para 5") and the ongoing supervision of the pregnancy.

• This code is for supervision only; do not use it for complications arising from grand multiparity.
• Always attempt to identify and code the specific trimester if documented, using O09.41-, O09.42-, or O09.43-.
• Sequence this code as a secondary diagnosis when a more specific reason for the encounter (e.g., routine prenatal visit, management of a specific complication) is the primary diagnosis.
