03.03D Billing Code Alberta: When and How to Use It 2026
Are you leaving money on the table during evening and weekend visits? The 03.03D premium code adds $15.18 to your base visit fee when you see patients between 5 PM and midnight on weekdays or during weekend days—yet many Alberta family physicians fail to claim it consistently. Understanding when and how to properly bill this premium can add thousands of dollars annually to your practice revenue.
Understanding the 03.03D After-Hours Premium
The 03.03D premium is one of Alberta's time-of-day differential codes designed to compensate physicians for providing care during less desirable hours. This code applies specifically to weekday evenings (5:00 PM to midnight) and weekend daytime hours (7:00 AM to 5:00 PM on Saturdays, Sundays, and designated holidays). It's billed in addition to your base assessment code—whether that's a 03.03A comprehensive visit, a 03.01A minor assessment, or any other eligible service code.
Many Alberta GPs underutilize this premium because they're uncertain about the exact time boundaries or worry about audit risk. The reality is that 03.03D is one of the most straightforward premiums to claim when properly documented. If you're seeing patients during walk-in evening clinics, Saturday morning appointments, or Sunday urgent care sessions, you should be claiming this code routinely. The key is ensuring your electronic medical record or clinic scheduling system captures the precise time of service, as this timestamp becomes your primary audit defense.
The financial impact accumulates quickly: a GP seeing just 10 evening or weekend patients per week adds over $7,800 annually in premium revenue. For practices offering extended hours to accommodate working patients, proper use of 03.03D can represent a significant portion of total billings—yet it requires no additional clinical work beyond accurate time documentation.
Billing Codes That Apply
Applies to any eligible assessment or procedure performed during weekday evenings (5:00 PM to 11:59 PM) or weekend/holiday daytime hours (7:00 AM to 4:59 PM). Can be combined with comprehensive visits, minor assessments, procedures, counseling codes, and most service codes except those with built-in after-hours compensation.
Cannot be billed with overnight premium codes (03.03E) or when the base service code already includes time-of-day compensation. One premium per visit encounter regardless of visit complexity.
Chart must include the exact time of service encounter (start time or time patient was seen), clearly showing the visit occurred within eligible hours, either in EMR timestamp, appointment schedule, or physician progress note.
Standard comprehensive assessment typically billed with 03.03D during evening or weekend clinics for patients requiring detailed history, examination, and management planning for new or complex problems.
Standard comprehensive visit rules apply—must meet complexity and time thresholds; maximum one comprehensive visit per patient per day except in specific circumstances.
Detailed history, physical examination findings, assessment/diagnosis, and management plan must be documented to support comprehensive level of service.
Used for simpler, focused assessments during after-hours clinics—common for acute minor complaints like URIs, simple rashes, or medication refills that can appropriately be combined with 03.03D.
Must represent a distinct, billable service; cannot be billed for administrative tasks or non-medical services.
Focused history and examination relevant to presenting complaint, diagnosis, and treatment plan sufficient to justify assessment-level service.
Common Documentation Mistakes That Trigger Claim Denials
The most common error is charts that state 'evening clinic' or 'weekend visit' without a specific timestamp. Alberta Health auditors require precise documentation showing the encounter occurred within eligible hours. Always ensure your EMR captures the exact time of service, or manually document it in your note (e.g., 'Patient seen at 18:30'). Appointment schedules alone may not suffice if there's no correlation to the actual clinical encounter time.
If you start seeing a patient at 4:45 PM and the visit extends past 5:00 PM, you cannot claim 03.03D unless the majority of the encounter or the actual service delivery occurred after 5:00 PM. Document when the clinical assessment actually began. Some GPs incorrectly claim the premium based on when the patient arrived versus when they were actually assessed—this creates audit vulnerability.
Certain service codes (like some on-call or emergency department codes) already incorporate after-hours compensation and cannot be billed with 03.03D. Always verify in the SOMB whether your base code is eligible for premium combination. The most frequent error occurs with hospital-based services where GPs assume clinic rules apply—they often don't.
The 03.03D weekend window closes at 5:00 PM. If you're seeing patients on Sunday evening after 5:00 PM or late Saturday night, you need to use the appropriate overnight premium (03.03E) instead. Many GPs default to 03.03D for all weekend work, but the time boundaries are strictly enforced. Know the exact cutoff times for your premium claims.

Frequently Asked Questions
Can I bill 03.03D for telephone visits conducted during evening hours?
Yes, if the telephone assessment code you're using is eligible for premium combination and the call occurs during eligible hours (weekday 5 PM-midnight or weekend 7 AM-5 PM). However, verify that your telephone visit code doesn't already include time-of-day compensation. Document the exact time the telephone encounter occurred in your chart notes.
What exactly counts as 'weekend' for 03.03D purposes—does it include statutory holidays?
Weekend includes Saturdays, Sundays, and designated Alberta statutory holidays. The eligible time window for these days is 7:00 AM to 4:59 PM. Outside these hours on weekends/holidays, you would use the overnight premium (03.03E) instead. The specific list of recognized statutory holidays is defined in the SOMB preamble.
If I see a patient at 4:50 PM and the visit extends to 5:15 PM, can I claim 03.03D?
This is a gray area that creates audit risk. The safest approach is to bill based on when the clinical encounter actually began. If you started your assessment at 4:50 PM, 03.03D would not apply even if the visit continued past 5:00 PM. However, if the patient was rooming/registration at 4:50 PM and your actual clinical assessment began at 5:05 PM, then 03.03D is appropriate—but your documentation must clearly reflect this timing distinction.
Can I bill both 03.03D and other premiums like the complex modifier on the same visit?
Yes, time-of-day premiums like 03.03D can generally be combined with complexity modifiers and other eligible service premiums, provided each premium's individual eligibility criteria are met and there are no specific co-billing restrictions listed in the SOMB. For example, you could bill 03.03A + 03.03D + a complexity premium if the clinical scenario supports all three, but always verify current combination rules as they can change.
Does my EMR timestamp automatically justify my 03.03D claim during an audit?
EMR timestamps provide strong supporting evidence, but auditors may request additional corroboration such as appointment schedules, clinic sign-in logs, or clinic operating hours documentation. The timestamp should reflect when the clinical service was actually provided, not just when the chart was opened or closed. Best practice is ensuring your EMR automatically captures service time and that this timestamp is visible in printed chart notes for audit purposes.
