    ICD-10-CM Code For Pneumonia Due To Hemophilus Influenzae: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group J14 includes pneumonia caused by the bacterium Hemophilus influenzae, covering pathogen-specific lower respiratory tract infections. These ICD-10-CM diagnosis codes are used to document clinical encounters for confirmed Hemophilus influenzae pneumonia, capturing disease severity, organ involvement, and treatment complexity. Accurate coding within the ICD-10-CM J14 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM J14: Pneumonia Due To Hemophilus Influenzae Overview

    The diagnoses in this group represent pneumonia caused by the bacterium Hemophilus influenzae affecting the lower respiratory tract. They target infectious disease and pulmonary systems and capture clinical details about pathogen-specific lung infection. Accurate coding is important for complete clinical documentation and supports appropriate reimbursement for services related to diagnosis and treatment.

    When to Use

    Use a code from this group when a clinical encounter documents pneumonia with Hemophilus influenzae identified as the causative organism. Codes apply when laboratory, culture, or other clinical evidence attributes the pneumonia to Hemophilus influenzae.

    Typical Clinical Scenarios

    • An adult patient presents to the emergency department with acute onset high fever, productive cough with purulent sputum, pleuritic chest pain, and shortness of breath. Chest radiograph shows a lobar consolidation consistent with community-acquired bacterial pneumonia, and sputum culture grows Haemophilus influenzae; the clinician documents pneumonia due to Haemophilus influenzae, so a code from this group is assigned. Typical codes: J14
    • An elderly nursing home resident with chronic obstructive pulmonary disease develops worsening cough, increased sputum production, hypoxia, and confusion over 48 hours; chest X-ray demonstrates a new infiltrate and blood cultures later identify Haemophilus influenzae as the pathogen. Because the acute infectious process is pneumonia due to Haemophilus influenzae on top of chronic lung disease, a code from this group is used to capture the infectious diagnosis. Typical codes: J14
    • A hospitalized patient recovering from influenza A develops secondary bacterial pneumonia with fever, increased respiratory distress, and new focal consolidation on imaging; bronchoalveolar lavage isolates Haemophilus influenzae as the causative organism, and the medical record specifies pneumonia caused by Haemophilus influenzae. A code from this group is assigned to identify the secondary bacterial pneumonia due to that organism. Typical codes: J14
