Extradural and subdural abscess, unspecified

This code signifies an infection characterized by a collection of pus located in the extradural (epidural) or subdural space of the brain or spinal cord, where the specific location (extradural or subdural) is not documented. These are serious intracranial or intraspinal infections that can lead to significant neurological deficits.

Apply this code when documentation clearly indicates an abscess within the extradural or subdural space, but the physician's notes do not specify whether it is extradural or subdural. This code is appropriate when the provider uses the term "extradural and subdural abscess, unspecified" or similar language without further clarification.

• Avoid using this code if the documentation specifies either an extradural (G06.0) or subdural (G06.1) abscess; always code to the highest level of specificity.
• Always review imaging reports (e.g., MRI, CT scans) and operative notes, if available, as they often provide the necessary detail to differentiate between extradural and subdural locations.
• Code any associated bacterial or other infectious agents as additional diagnoses to fully describe the patient's condition.
