Oth mult gest w two or more monochorionic fetuses, unsp tri

This code identifies a pregnancy involving two or more fetuses that share a single chorion, where the specific type of multiple gestation is not otherwise classified. It indicates a monochorionic pregnancy with at least two fetuses, without specifying the trimester.

Apply this code when documentation confirms a monochorionic multiple gestation with two or more fetuses, but the specific type (e.g., monoamniotic, diamniotic) is not detailed, and the trimester is not recorded. This is appropriate for initial encounters or when complete information is unavailable.

• Ensure documentation explicitly states "monochorionic" and "multiple gestation" with at least two fetuses.
• Avoid using this code if a more specific code for the type of monochorionic multiple gestation (e.g., monoamniotic, diamniotic) is available and supported by documentation.
• This code is for the maternal record; codes for the fetal conditions would be reported separately.
