Placental disorders

  • O43 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
  • The 2020 edition of ICD-10-CM O43 became effective on October 1, 2019.
  • This is the American ICD-10-CM version of O43 - other international versions of ICD-10 O43 may differ.
Type 2 Excludes
Type 2 Excludes Help
A type 2 excludes note represents "not included here". A type 2 excludes note indicates that the condition excluded is not part of the condition it is excluded from but a patient may have both conditions at the same time. When a type 2 excludes note appears under a code it is acceptable to use both the code (O43) and the excluded code together.
