Abnormal echoencephalogram

This code signifies an abnormal finding on an echoencephalogram, a diagnostic ultrasound of the brain. It indicates the presence of structural or functional irregularities detected during the examination, without specifying the underlying cause.

Use this code when the medical record documents an "abnormal echoencephalogram" and no more specific diagnosis is yet established. This is often an initial finding that prompts further investigation. Documentation must clearly state the echoencephalogram was performed and yielded abnormal results.

• This is a "sign and symptom" code; always search for a more definitive diagnosis if available.
• Do not use if a specific diagnosis explaining the abnormal echoencephalogram (e.g., hydrocephalus, intracranial hemorrhage) is documented.
• Sequence this code after any definitive diagnosis if the abnormal echoencephalogram is a manifestation of that condition.
