Thank you both for your help! I guess I'm still confused why O90.0 wouldn't be appropriate, even if it is after the puerperium period? The guidelines make it seem like it is okay to code Chapter 15 codes after the puerperium period, as long as the condition is related to the pregnancy. The guidelines state the "Postpartum period begins immediately after delivery and continues for six weeks following delivery." It also states the "Peripartum period is defined as the last month of pregnancy to five months postpartum." As I stated before, it does state it is okay to code Chapter 15 codes after both these timeframes, as long as the provider documentation correlates the complication to the pregnancy.
I just feel that O90.0 best describes the condition.
If I did go with a chapter 19 (Injury, Poisoning, and Certain Other Consequences of External Causes) code, do you think S31.105A (Unspecified open wound of abdominal wall, periumbilic region without penetration into peritoneal cavity) or some other option?
Thanks again!
