Supervision of elderly multigravida, unspecified trimester

This code signifies the medical oversight provided to an expectant mother who is considered elderly (typically 35 years or older at the time of delivery) and has had two or more previous pregnancies. It indicates that the supervision is for a routine, uncomplicated pregnancy in this demographic, without specifying the trimester of gestation.

Apply this code when documentation indicates routine prenatal care for an elderly multigravida where the specific trimester is not recorded or is unknown. This is appropriate for initial encounters or when trimester-specific codes are not yet applicable or available. Supporting documentation would include age, gravidity, and a lack of documented complications.

• Do not use if any pregnancy complications are documented; instead, code the specific complication.
• If the trimester is known, use the more specific O09.51- (first trimester) or O09.53- (third trimester) codes.
• This code should be sequenced as a primary diagnosis when the reason for the encounter is routine supervision of this specific patient demographic.
