B550
B550 – B550
OHIP Paediatrics Code · Schedule of Benefits
When to Use
- Use B550 for the initial assessment and management of a patient presenting with symptoms suggestive of a stroke, even if the diagnosis is later ruled out.
- B550 is appropriate for the first encounter with a patient experiencing a transient ischemic attack (TIA) and requires urgent neurological assessment.
- Bill B550 when a patient presents to the emergency department with sudden onset neurological deficits requiring immediate evaluation, regardless of the final disposition.
Common Pitfalls
- Billing B550 for follow-up visits or routine neurological assessments that do not meet the criteria for an acute stroke or TIA evaluation.
- Submitting B550 when the patient's presentation is clearly attributable to a non-vascular cause, such as a migraine or seizure disorder, without suspicion of stroke.
- Failing to differentiate B550 from other emergency visit codes (e.g., A007) when the primary complaint is not stroke-related, even if neurological symptoms are present.
Billing Tips
- Ensure the patient's chart clearly documents the acute onset of neurological symptoms and the rationale for suspecting a stroke or TIA at the time of the encounter.
- Confirm that the assessment and management provided are consistent with the urgency required for a potential stroke or TIA, justifying the use of B550.
