J15.0 is the authoritative medical code for Pneumonia due to Klebsiella pneumoniae. This classification is used in medical billing and clinical recording to specify the clinical criteria for pneumonia due to klebsiella pneumoniae (ICD-10-CM J15.0), ensuring healthcare documentation aligns with 2026 federal coding standards.
Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.
Official Registry Overview & Definition
Pneumonia due to Klebsiella pneumoniae is a billable ICD-10-CM diagnosis code J15.0. Includes: bronchopneumonia due to bacteria other than S. pneumoniae and H. influenzae. Excludes1 (not coded here): chlamydial pneumonia J16.0; congenital pneumonia P23.-; Legionnaires' disease A48.1; spirochetal pneumonia A69.8. Excludes2 (not included here): allergic or eosinophilic pneumonia J82; aspiration pneumonia NOS J69.0; meconium pneumonia P24.01; neonatal aspiration pneumonia P24.-; pneumonia due to solids and liquids J69.-; congenital pneumonia P23.9; lipid pneumonia J69.1; rheumatic pneumonia I00; ventilator associated pneumonia J95.851. Code first: , if applicable, associated influenza (J09.X1, J10.0-, J11.0-). Use additional code: code, if applicable, to identify resistance to antimicrobial drugs Z16.-. Code also: , if applicable, any associated condition such as:; abscess J85.1; aspiration pneumonia J69.-.

Frequently Asked Questions (FAQ) & Clinical Guidance
What can't be coded together with J15.0?
Per Excludes1 instructions, J15.0 must not be reported with: chlamydial pneumonia (J16.0); congenital pneumonia (P23.-); Legionnaires' disease (A48.1); spirochetal pneumonia (A69.8).
Can J15.0 be reported alongside related conditions?
Per Excludes2 instructions, J15.0 and the following may both be reported when both are present: allergic or eosinophilic pneumonia (J82); aspiration pneumonia NOS (J69.0); meconium pneumonia (P24.01); neonatal aspiration pneumonia (P24.-).
Does J15.0 need to be sequenced after another code?
Yes. Code first: , if applicable, associated influenza (J09.X1, J10.0-, J11.0-).
Is an additional code needed with J15.0?
Use additional code(s) to specify: code, if applicable, to identify resistance to antimicrobial drugs (Z16.-).
