Oth mental disorders comp pregnancy, second trimester

This code signifies the presence of a pre-existing or newly diagnosed mental disorder, other than those specifically categorized elsewhere (e.g., substance-related, mood disorders), that is impacting a pregnancy during the second trimester. This includes conditions like anxiety disorders, personality disorders, or eating disorders when they complicate the gestational period.

Apply this code when a pregnant patient in her second trimester is diagnosed with a mental disorder that is not a mood disorder, substance-related disorder, or postpartum-specific condition, and the clinician explicitly documents its impact on the pregnancy. Documentation should clearly state the type of mental disorder and the trimester.

• Always sequence this code as a secondary diagnosis, following the code for the specific mental disorder (e.g., F41.1 for generalized anxiety disorder).
• Ensure the medical record explicitly states "second trimester" to support the specificity of this code.
• Distinguish from codes for mood disorders (O99.31-) or substance-related disorders (O99.32-) complicating pregnancy.
