About J14
J14 is the ICD-10-CM diagnosis code for pneumonia due to Hemophilus influenzae. It belongs to block J09-J18 (influenza and pneumonia) and chapter 10 (diseases of the respiratory system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Don't report J14 together with the conditions in its Excludes1 note: congenital pneumonia due to H. influenzae (P23.6).
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.
In MS-DRG v44.0, it is part of the grouping logic for DRG 193 (Simple Pneumonia and Pleurisy with MCC, relative weight 1.2825), DRG 194 (Simple Pneumonia and Pleurisy with CC, relative weight 0.7888), DRG 195 (Simple Pneumonia and Pleurisy without CC/MCC, relative weight 0.6063), DRG 791 (Prematurity with Major Problems, relative weight 4.1075), DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), DRG 974 (HIV with Major Related Condition with MCC, relative weight 3.0506) and 2 more, in MDC 04 (Diseases and Disorders of the Respiratory System), MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period) and MDC 25 (Human Immunodeficiency Virus Infections), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 482.2 (pneumonia due to Hemophilus influenzae [H. influenzae]).
