About the O89 Code Range

After childbirth, anesthesia can have complications involving the lungs, heart, brain and spinal cord, or the anesthesia process itself. The puerperium is the period after childbirth.

O89.0 groups lung complications. It separates lung inflammation from breathing something in (O89.01) from other lung complications (O89.09). Separate subdivisions identify heart complications (O89.1) and brain or spinal cord complications (O89.2).

The remaining subdivisions distinguish toxic reactions to local anesthesia, headaches and other complications from spinal or epidural anesthesia, and failed or difficult intubation. They also include other and unspecified anesthesia complications.
