P23.9
ICD-10-CMThis code represents an inflammatory condition of the lung tissue present at birth, where the specific causative agent or type of pneumonia is not documented. It indicates an infection acquired in utero or during the birthing process, affecting the neonate's respiratory system.
Use this code when the medical record clearly states "congenital pneumonia" but lacks further specificity regarding the type (e.g., bacterial, viral, aspiration) or the organism involved. This code is appropriate when the physician's documentation confirms the pneumonia was present at birth or developed shortly thereafter due to perinatal factors.
