What This Code Means

A pregnant woman has a disease or medical condition (other than those with specific codes) that is complicating her pregnancy during the first trimester.

Coding Tips

• •This is a catch-all code for conditions not specifically classified elsewhere; always attempt to use a more specific code if available
• •Document the specific disease or condition clearly in the medical record to justify use of this code rather than a more specific diagnosis code
