    Please explain the correct coding for this condition with the appropriate code and what is the best justification for your selection.
    the cyst code is 
    N83.291
    Other ovarian cyst, right side


    An antenatal ultrasound was performed for a pregnant woman at 12 weeks of pregnancy. The finding indicates a simple cyst of the right ovary. Given that this is a pregnancy what will be the most correct coding for this diagnosis.

    One coder suggested:
    o26.891 and N83.291
    026.291 =Other specified pregnancy related conditions, first trimester.
    o26 series Maternal care for other conditions predominantly related to pregnancy


    Another coder suggested:
    034.891 and N83.291
    o34.81 = Maternal care for other abnormalities of pelvic organs, first trimester
    o34 series Maternal care for abnormality of pelvic organs + Use additional code for specific condition

    ​I would use the code O99.89 and N83.291.
    O99.89 -  Other specified diseases and conditions complicating pregnancy, childbirth and the puerperium

    The reason is that under the heading for O99.8, the conditions included are D00-D48, H00-H95, M00-N99 and Q00-Q99. I don't think that the simple cyst is a pregnancy related condition nor is it an abnormality of a pelvic organ.

    I hope this helps...

    More than likely, this is an incidental finding on a 12-week ultrasound.  Unless there is documentation that it is affecting the pregnancy, I would not use a O26.- code, "Maternal care for other conditions predominantly related to pregnancy".  I didn't look to see if anything else would be more appropriate.
