To avoid reporting J18.9 perhaps a query is in order for pneumonia specificity ?
PEPPER (PEPPER is an electronic report that provides provider-specific Medicare data statistics for discharges/services vulnerable to improper payments) data allows clinical documentation integrity (CDI) departments to compare the volume of cases involving simple pneumonia to those involving respiratory infections.
In addition to comorbidities, the causative organism or etiology affects the severity of pneumonia.
With an inability to accurately identify the causative organism, providers often classify pneumonia as community-acquired pneumonia (CAP) or hospital/healthcare-associated pneumonia (HAP/HCAP).
HAP is defined by the American Thoracic Society as a lung infection that begins in a non-intubated patient within 48 hours of admission, but it has more commonly been used interchangeably with HCAP to describe pneumonia associated with organisms that result from exposure to healthcare (e.g., nursing homes, dialysis, etc.) These are broad terms that allow the provider to differentiate a simple pneumonia, CAP, from a complex pneumonia (HAP/HCAP, e.g., one associated with a more virulent pathogen), but ICD-10-CM does not index using these terms, so they both default to J18.9, pneumonia, unspecified organism.
The Merck Manual, states the most common pathogens associated with CAP are streptococcus pneumoniae, haemophilus influenzae, atypical bacteria (i.e., chlamydia pneumoniae, mycoplasma pneumoniae, legionella species), and viruses.
Updated guidelines have clinically eliminated HCAP as a pneumonia classification tool, instead focusing on the severity of pneumonia.
Some CDI departments only query for pneumonia specificity if HAP/HCAP is documented, since it can result in a DRG shift, but not when CAP is documented.
It is essential to achieve complete and accurate documentation, code assignment, and reporting of diagnoses and procedures.
