O68 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
Short description: Labor and delivery comp by abnlt of fetal acid-base balance
The 2023 edition of ICD-10-CM O68 became effective on October 1, 2022.
This is the American ICD-10-CM version of O68 - other international versions of ICD-10 O68 may differ.

ICD-10-CM Coding Rules

O68 is applicable to maternity patients aged 12 - 55 years inclusive.
O68 is applicable to female patients.

Applicable To

Fetal acidemia complicating labor and delivery
Fetal acidosis complicating labor and delivery
Fetal alkalosis complicating labor and delivery
Fetal metabolic acidemia complicating labor and delivery

Type 1 Excludes

Type 1 Excludes Help

A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as O68. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

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 (O68) and the excluded code together.

Applicable To
- Depressed fetal heart rate tones complicating labor and delivery
- Fetal bradycardia complicating labor and delivery
- Fetal heart rate decelerations complicating labor and delivery
