What This Code Means

The placenta separates prematurely from the uterine wall during the first trimester of pregnancy without specification of the type of separation.

Coding Tips

  • •First trimester placental abruption is uncommon; verify documentation supports this timing
  • •If the type of abruption is documented, use a more specific code from the O45.0-O45.8 range
