A313 – Medical specific assessment
OHIP General Listings Code — CONSULTATIONS AND VISITS · Schedule of Benefits
A medical specific assessment is a service rendered by a specialist in a place other than a patient's home. It requires a full history of the presenting complaint and a detailed examination of the affected part(s), region(s), or system(s) needed to make a diagnosis, and/or exclude disease, and/or assess function. In addition to the common elements, all services described as assessments, or as including assessments (e.g. consultations), include the following specific elements as per : A. A direct physical encounter with the patient including taking a patient history and performing a physical examination. B. Other inquiry (including taking a patient history), carried out to arrive at an opinion as to the nature of the patient's condition, (whether such inquiry takes place before, during or after the encounter during which the physical examination takes place) and/or follow-up care. C. Performing any procedure(s) during the same encounter as the physical examination, unless the procedure(s) is(are) separately listed in the Schedule and an amount is payable for the procedure in conjunction with an assessment. D. Making arrangements for any related assessments, procedures or therapy, and/or interpreting results. E. Making arrangements for follow-up care. F. Discussion with, and providing advice and information, including prescribing therapy to the patient or the patient's representative, whether by telephone or otherwise, on matters related to the service and results. G. When medically indicated, monitoring the condition of the patient and intervening, until the next insured service is provided. H. Providing premises, equipment, supplies, and personnel for the specific elements of the service except for any aspect(s) that is (are) performed in a hospital or nursing home.
When to Use
- Bill A313 for a specialist's initial comprehensive assessment of a new neurological condition, distinct from a general practitioner's assessment (A007).
- Use A313 when a specialist performs a detailed assessment of a specific orthopedic injury, requiring a focused history and physical exam, rather than a general consultation (A310).
- A313 is appropriate for a specialist's assessment of a complex dermatological issue, involving a thorough examination of the affected skin areas and a detailed history of the rash or lesion.
Common Pitfalls
- Billing A313 for a follow-up visit that does not involve a new comprehensive assessment; these should be billed as intermediate (A311) or general assessment (A007) codes depending on the provider.
- Submitting A313 when the service is rendered in a patient's home, which would require different assessment codes or potentially be unbillable.
- Failing to document the specific elements of a detailed history and physical examination of the affected system(s), which is a core requirement for A313.
Billing Tips
- Ensure the patient's medical record clearly delineates the specific complaint, the detailed examination performed, and the specialist's diagnostic reasoning to support the A313 claim.
- When applicable, append the E078 premium for a chronic disease assessment if the specialist is in Physical Medicine, the patient has a documented chronic condition, and the service meets all other E078 criteria.
