About the O74 Code Range
Anesthesia during labor or delivery can involve complications affecting the lungs, heart, or central nervous system, meaning the brain and spinal cord.
The subdivisions separate aspiration-related lung inflammation (O74.0) from other lung complications (O74.1). Heart complications have O74.2, and central nervous system complications have O74.3. Other subdivisions identify a toxic reaction to local anesthesia (O74.4), headaches from spinal or epidural anesthesia (O74.5), and other complications of those methods (O74.6). Failed or difficult placement of a breathing tube has O74.7. The remaining subdivisions identify other anesthesia complications (O74.8) or an unspecified complication (O74.9).
