This patient was admitted when MRI revealed cerebral aneurysm. After admission, a cerebral angiogram was performed and showed nonruptured arteriosclerotic aneurysm of the anterior cerebral artery. An aneurysmectomy by anastomosis was performed using Marlex graft replacement. What codes are assigned?

To determine the appropriate codes for this patient's case, you need to refer to the respective code manuals for ICD-9-CM (International Classification of Diseases, 9th Revision, Clinical Modification) and ICD-10-CM (International Classification of Diseases, 10th Revision, Clinical Modification) as well as ICD-9-CM Procedure and ICD-10-PCS (Procedure Coding System) manuals.

First, let's address the ICD-9-CM Diagnosis Codes with POA Indicator:

1. Cerebral aneurysm: Since the MRI revealed a cerebral aneurysm, you need to find the specific code for cerebral aneurysm in the ICD-9-CM Diagnosis Code manual. It could be located under the section "Other Disorders of Circulatory System" (codes 417-459). You should also note down the Present on Admission (POA) Indicator for this diagnosis.

2. Nonruptured arteriosclerotic aneurysm of the anterior cerebral artery: Similarly, you would need to find the appropriate code for this specific diagnosis in the ICD-9-CM Diagnosis Code manual.

Now, let's move on to the ICD-9-CM Procedure Codes:

3. Aneurysmectomy by anastomosis: You would need to search for the correct code in the ICD-9-CM Procedure Code manual. Look for the section that covers "Operations on the Great and Intracranial Arteries" (codes 39.50-39.51) or relevant procedures related to aneurysmectomy.

For the ICD-10-CM and ICD-10-PCS Codes:

Since ICD-10 code manuals contain more codes than can be included in this response, you would follow a similar process as mentioned above. Refer to the respective code manuals for ICD-10-CM diagnoses and ICD-10-PCS procedures. In the ICD-10-CM code manual, you would locate the appropriate codes for the diagnoses mentioned. For the ICD-10-PCS code, you would find the specific code for the aneurysmectomy procedure.

To accurately assign the codes for this patient's case, it's crucial to access the complete code manuals and ensure you select the specific codes that match the patient's details.
