OHIP After-Hours Premium (Q012 & Q016): How to Avoid an AD9 Rejection

The after-hours premium is one of the easiest ways to increase your billing for evening and weekend care: a straight 30% bonus on top of eligible fee codes. It's also one of the easiest premiums to get rejected, because it doesn't apply to every code you might expect.

If you've ever submitted Q012 or Q016 and had it bounce back with AD9: not allowed alone, this is why.

What Q012 and Q016 actually pay

Q012 is the FHO after-hours bonus (30% of the eligible fee), payable for rostered patients seen on weekday evenings after 5 p.m. or on weekends and statutory holidays. Q016 works the same way for the equivalent FHG/comprehensive care model context. Both are out-of-basket premiums, but they only attach to a specific list of underlying codes.

Codes that DO qualify for the after-hours premium

Based on the current billing matrix, the after-hours premium can be added to:

  • Assessments: A001, A003, A004, A007, A008, A888, Q888
  • Periodic health exams: K017, K130, K131, K132, K133
  • Chronic disease management: K030, Q050
  • Mental health: K005, K013/K033

This is the part that surprises people: yes, mental health codes like K005 and educational counselling (K013/K033) are eligible for the after-hours bonus. Many physicians assume they aren't and leave money on the table.

Codes that do NOT qualify (and will trigger AD9)

This is the more important list, because billing the premium against any of these is what causes the rejection:

  • Virtual/limited care: A101 (video), A102 (phone), A905 (limited consultation)
  • E-consults: K738, K739
  • Periodic health: A002 (18-month well-baby visit)
  • Chronic disease: K029, K032, K037, K022, K023, G271
  • Mental health: K002, K003, K008, K028, A680/K680, K623
  • Pregnancy: P003, P004, P005, P008, A920
  • Tests, vaccines, and procedures as a category

If you bill Q012 against any code in this list, expect an AD9: not allowed alone rejection on your Claims Error Report. The underlying service is fine; it's the premium attached to it that gets kicked back.

How to avoid the rejection

  1. Check the underlying code before adding Q012/Q016. Not the visit type, the specific fee code. A007 qualifies; A101 (its virtual-care cousin) does not.
  2. Don't assume mental health codes are excluded. K005 and K013/K033 qualify; K002, K003, K008, and K623 don't. It's easy to lump all "K-codes" together (don't!).
  3. Remember the timing rule. The premium only applies for services after 5 p.m. on weekdays or any time on weekends and statutory holidays (Family Day, Good Friday, Victoria Day, Canada Day, Civic Holiday, Labour Day, Thanksgiving, New Year's, and Dec. 25–31 inclusive). A qualifying code billed at 3 p.m. still won't earn the premium.
  4. Roster status matters. Q012 requires the patient to be rostered to your FHO. Non-rostered after-hours visits don't qualify for this specific premium.

Related rejection to watch for: Q014/Q015 newborn premiums

A closely related trap: the Q014/Q015 newborn episodic premiums can only be billed alongside a valid A007 assessment, on the same service date, for a patient under age 1. Bill it with any other assessment code, or on a different date than the A007, and it will reject with AD9: not allowed alone or A2A: outside of age limit. Same failure pattern, different code.

The fix is catching it before submission, not after

AD9 rejections aren't usually a documentation problem; they're a pairing problem. The visit was legitimate; the premium was just attached to a code that was never eligible for it. That's exactly the kind of error that's invisible until the Claims Error Report shows up weeks later.

Quip checks premium eligibility automatically, so Q012 and Q016 only ever attach to codes that actually qualify. No manual list-checking required.
