Confirm site and side of the bleed and pick up the most precise code from I60.XX series.
One important change that ICD-10 has introduced is that it clearly specifies that the codes I60.XX are for subarachnoid hemorrhage in nontraumatic in nature. Once you have confirmed that the bleed was not preceded by trauma, you can easily hit the right code if you look for site of hemorrhage and side of hemorrhage.
Step 1: Determine the Site of the Bleed
Your first guide to the right code for subarachnoid hemorrhage which is not a consequence of trauma is to determine the site the bleed in the cerebral circulation. Your first step is to determine if the site of the bleed was the vertebral artery, basilar artery, anterior or posterior communicating artery, middle cerebral artery, carotid artery, or other intracranial arteries.
“This is much more specific than previously reported under ICD-9,” says Gregory Przybylski, MD, director of neurosurgery at the New Jersey Neuroscience Institute, JFK Medical Center in Edison. “Sometimes, the actual source may not be determinable when more than one aneurysm is present in close proximity to one another but on different vessels. Unspecified diagnostic codes allow for reporting such conditions.”
Step 2: Confirm If the Bleed Was Left or Right Sided
The next important step is to check in the clinical note if the hemorrhage was on the right or the left side of the head.
“You should report the most specific ICD-10 diagnostic code that you can based on the information available to you,” Przybylski says. “Remember that for this first year of ICD-10 implementation, CMS is only requiring ICD-10 family accuracy (first three alphanumeric characters before the decimal).”
Note: If, however, your surgeon does not mention the side of the hemorrhage, you may report the unspecified codes for different sites.
