Final answer:
The proper ICD-10-CM codes for a patient admitted for repair of a recurrent incarcerated ventral hernia and diagnosed with pneumonia, leading to canceled surgery are: K43.9 for the hernia and J18.9 for the unspecified pneumonia.
Step-by-step explanation:
The question asks to identify the correct coding for a patient admitted to the hospital for repair of a recurrent incarcerated ventral hernia but diagnosed with pneumonia after a chest x-ray, leading to a canceled surgery. The patient is placed on antibiotics for the pneumonia. Using the ICD-10-CM (International Classification of Diseases, Tenth Revision, Clinical Modification), the correct codes would be K43.9 for the unspecified ventral hernia without obstruction or gangrene and J18.9 for pneumonia, unspecified organism, since the specific type of bacteria responsible for the pneumonia is not mentioned.
