I'm stuck on this and I can't find a definitive answer anywhere. A routine prenatal encounter requires a Z34 code unless a code from chapter 15 is used. If a code from chapter 15 is used does it automatically make it a high risk pregnancy?
For example if a O21.9 dx is coded then what is the first listed diagnosis? You can't use a z34 code but do you then use an O09.90-O09.93 dx?
See my screenshots below. The first is the coding guidelines and the second is just a list from the medicare medical necessity document that one of these codes is required for certain labs. So if you can't use a Z34 code. How do you get the lab covered? Use an O09 code?
