About coding Pyelocystitis puerperal
The ICD-10-CM code for Pyelocystitis puerperal is O86.29 (Other urinary tract infection following delivery).
Within O86.2, choose O86.29 (Other urinary tract infection following delivery) only when documentation doesn't support a more specific option: unspecified (O86.20), infection of kidney following delivery (O86.21) and infection of bladder following delivery (O86.22).
Use an additional code (B95-B97), to identify infectious agent.
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
