Maternal care for oth abnlt of pelvic organs, third tri

This code signifies antenatal care provided to a pregnant patient in her third trimester due to an identified abnormality of her pelvic organs (e.g., uterine fibroids, ovarian cysts, or pelvic masses) that is not specifically classified elsewhere. These abnormalities are pre-existing or develop during pregnancy and require ongoing monitoring or management.

Apply this code when documentation indicates maternal care for a pelvic organ abnormality during the third trimester of pregnancy. This includes conditions like symptomatic uterine leiomyomas, adnexal masses, or other structural anomalies of the pelvic organs that are not causing obstructed labor or other specified complications. Documentation should clearly state the trimester and the specific pelvic organ abnormality.

• Ensure the documentation specifies the third trimester; otherwise, a different trimester-specific code should be used.
• Do not use this code if the pelvic abnormality is explicitly causing obstructed labor (e.g., O65.5).
• Always sequence this code as a secondary diagnosis following the primary code for the pregnancy (Z3A.xx).
