About coding staphylococcal pneumonia
The ICD-10-CM code for staphylococcal pneumonia is J15.20 (Pneumonia due to staphylococcus, unspecified). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on J15.20.
Within J15.2, choose J15.20 (unspecified) only when documentation doesn't support a more specific option: aureus (J15.21) and other staphylococcus (J15.29).
Code first: , if applicable, associated influenza (J09.X1, J10.0-, J11.0-).
As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.
