O29.0Pulmonary complications of anesthesia during pregnancy

O29.0 is the ICD-10-CM diagnosis code for pulmonary complications of anesthesia during pregnancy. It belongs to category O29 (complications of anesthesia during pregnancy), block O20-O29 (other maternal disorders predominantly related to pregnancy) and chapter 15 (pregnancy, childbirth and the puerperium). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within O29 (complications of anesthesia during pregnancy), O29.0 is specifically for pulmonary complications of anesthesia during pregnancy. Related codes cover cardiac complications of anesthesia during pregnancy (O29.1), central nervous system complications of anesthesia during pregnancy (O29.2), toxic reaction to local anesthesia during pregnancy (O29.3), spinal and epidural anesthesia induced headache during pregnancy (O29.4), other complications of spinal and epidural anesthesia during pregnancy (O29.5), failed or difficult intubation for anesthesia during pregnancy (O29.6), other complications of anesthesia during pregnancy (O29.8) and unspecified complication of anesthesia during pregnancy (O29.9).

To report this condition, pick the subcode that matches the documentation: O29.01 (pregnancy), O29.02 (pregnancy) and O29.09 (pregnancy).

Use an additional code, if necessary, to identify the complication.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
