03.03A vs 03.03C
— When to Bill a Complex vs Standard Office Visit (Alberta 2026)
Every time you bill 03.03A for a multi-problem patient visit that truly warranted 03.03C, you're leaving $35.70 on the table. With the 2026 SOMB fee schedule, the gap between a standard office visit at $37.15 and a complex visit at $72.85 represents nearly double the revenue—yet many Alberta family physicians consistently underbill because they're unsure when complexity is truly justified. Understanding the precise eligibility criteria and documentation requirements for 03.03A versus 03.03C is critical to protecting your practice revenue while staying audit-compliant.
When Does a Visit Qualify as Complex? The 03.03A vs 03.03C Decision
The fundamental distinction between 03.03A and 03.03C isn't just about time—it's about clinical complexity and decision-making burden. Code 03.03A at $37.15 is designed for focused, single-problem encounters with established patients where the clinical decision is straightforward and typically completed in under 15 minutes. Think: a medication refill with stable vitals, a single uncomplicated skin complaint, or a routine follow-up for one controlled condition.
Code 03.03C at $72.85 applies when you're managing a complex multi-problem encounter OR a single but highly complex problem requiring extended assessment, typically 20+ minutes. This includes new patients to your practice, established patients presenting with new complex issues, or visits where multiple interrelated problems demand integrated decision-making. A patient presenting with uncontrolled diabetes, new chest pain requiring cardiac workup, AND medication reconciliation after a hospital discharge is a clear 03.03C scenario—not three separate 03.03A visits compressed into one appointment.
The critical audit-protection principle: document what made the visit complex. Alberta Health reviews patterns, and physicians who bill 03.03C for every encounter will face scrutiny. Your chart must reflect either multiple distinct problems addressed with separate assessment and management plans, or a single problem requiring extended time with documented rationale (differential diagnosis considered, multiple treatment options discussed, coordination with specialists, etc.). When complexity is genuine and documented, 03.03C is not just justified—it's the accurate representation of the cognitive work you performed.

Common Documentation Mistakes That Trigger Claim Denials
Your chart says 'Multiple issues discussed' but only documents one problem in detail. Auditors will downcode to 03.03A and recover the $35.70 difference. Correct approach: List each problem as a separate numbered or bulleted item with individual assessment and plan (e.g., '1. Hypertension: BP 156/94, increased ramipril to 10mg. 2. Type 2 DM: A1C 8.2%, referred to dietitian. 3. Insomnia: trial zopiclone 5mg PRN').
Chart states 'Patient has hypertension and COPD' in the problem list but only addresses an acute URI during the visit. The chronic diseases weren't managed, so 03.05W doesn't apply. Correct approach: Only bill 03.05W when you document a specific action for the chronic condition—medication adjustment, symptom review with clinical decision, lab interpretation, patient education with counseling note, or care plan modification.
Chart says 'Visit took 25 minutes' but describes a single straightforward problem. Time is an indicator, not the sole criterion—clinical complexity must be evident. Correct approach: Document why the time was needed (extensive patient education required, multiple treatment options discussed with shared decision-making, detailed medication reconciliation post-discharge, coordination with three specialists, etc.).
Chart says 'Screened for depression' but doesn't name the tool or record the score. Alberta Health will deny the $50.28 premium. Correct approach: Document 'PHQ-9 administered: score 16/27 (moderately severe depression). Discussed results with patient, started sertraline 50mg daily, safety plan reviewed, follow-up in 2 weeks.' Tool name, numerical score, and management plan are all mandatory.
New patients often require more time for history-taking, but if the clinical problem is simple and decision-making straightforward, 03.03A may be appropriate. Billing 03.03C automatically for all new patients creates an audit-triggering pattern. Correct approach: Bill based on complexity, not patient status. A new patient with a single minor complaint and straightforward plan is 03.03A; a new patient with multiple chronic conditions requiring comprehensive assessment and coordinated care plan is 03.03C.
Real Example: Maximum Revenue Scenario
58-year-old established patient presents for multiple issues: uncontrolled Type 2 diabetes (recent A1C 8.9%), worsening shortness of breath related to known COPD, and low mood affecting medication adherence. Visit involves medication adjustments for diabetes and COPD, spirometry requisition, PHQ-9 screening (score 12/27), counseling on medication adherence and lifestyle, and coordination with respirology for COPD optimization. Total visit time 28 minutes.
Frequently Asked Questions
Can I bill 03.03C for a visit that involves three problems if each problem is relatively simple on its own?
Yes, if managing the three problems together required integrated clinical decision-making and extended time (typically 20+ minutes). The complexity can arise from the interaction between problems (e.g., choosing antihypertensives that won't worsen diabetes or COPD) or from the cumulative cognitive load of addressing multiple issues in one encounter. Document all three problems separately with individual assessments and plans, and note if there was clinical complexity in coordinating care. If each problem was truly independent and straightforward, and total time was under 15 minutes, 03.03A may be more appropriate—but this scenario is rare when genuinely managing three distinct issues.
If I bill 03.03C at $72.85, how many times can I add 03.05W for chronic disease management?
You can add 03.05W up to three times per encounter (once for each distinct chronic condition actively managed), regardless of whether the base code is 03.03A or 03.03C. Each 03.05W adds $27.39, so managing three chronic conditions with a 03.03C visit could total $72.85 + $27.39 + $27.39 + $27.39 = $155.02. The key requirement: each chronic condition must be explicitly named in your chart with a documented management decision (medication change, lab ordered, symptom assessment with plan adjustment, etc.)—simply listing the condition in the problem list without active management during that visit doesn't qualify for 03.05W.
What's the biggest red flag that triggers an audit for 03.03C billing?
Billing 03.03C for 90-100% of your patient encounters, regardless of acuity or patient type, will trigger pattern-based audit review by Alberta Health. Auditors expect a realistic mix reflecting your actual practice: some visits are straightforward and warrant 03.03A, while truly complex encounters justify 03.03C. A typical family practice might bill 03.03C for 40-60% of visits, but this varies by practice demographics and complexity. The safeguard: ensure every 03.03C claim is supported by chart documentation showing either multiple problems listed with separate management plans, or extended time with documented rationale for complexity (differential diagnosis explored, multiple treatment options discussed, care coordination required, etc.).
Can I bill 03.03A for a quick visit and still add 03.05W if I managed a chronic condition?
Yes, absolutely. Code 03.05W at $27.39 is an add-on premium that works with either 03.03A or 03.03C. For example, a 10-minute focused visit for a medication refill where you also reviewed recent lab results and adjusted the patient's diabetes medication would be billed as 03.03A ($37.15) + 03.05W ($27.39) = $64.54. The requirement is that the chronic condition was specifically discussed and actively managed during the visit—documentation must show the condition name and a management action. You cannot add 03.05W if the chronic disease was only mentioned in passing without any clinical decision or management intervention during that encounter.
How do I document a 03.03C visit to defend against potential audit years later?
Your chart must answer the question 'Why was this visit complex?' Use structured documentation: (1) List each problem as a separate numbered item (e.g., '1. Uncontrolled HTN, 2. New-onset chest pain, 3. Medication reconciliation post-discharge'); (2) For each problem, document your assessment and specific management plan including medications prescribed/adjusted, investigations ordered, referrals made, and patient education provided; (3) If extended time was a factor, note why (e.g., 'Extensive counseling on cardiovascular risk reduction, discussed pros/cons of three medication options, coordinated care with cardiology'); (4) Include follow-up timeline. Generic statements like 'Multiple issues discussed, plan reviewed' are insufficient. Detailed, problem-oriented documentation showing the clinical complexity and cognitive work you performed is your audit defense for the $72.85 fee.
