1What Is the A020 OHIP Code?
A020 is a billing code for complex dermatology assessments within Ontario's OHIP system. This code is applicable when a patient with severe or obscure dermatologic conditions requires an in-depth evaluation by a dermatologist. Typical situations include severe blistering disorders, erythroderma, or widespread drug eruptions where both multiple body regions and systemic effects must be evaluated in a single visit.
The complexity of these conditions necessitates a thorough approach, often involving detailed history taking, comprehensive physical examination, and possibly coordination with other specialists. Missing this code can occur if the full criteria aren't explicitly documented, or if the complexity isn't adequately justified in the patient record.

3Eligibility Requirements
To be eligible for billing under A020, the condition must meet criteria indicating its high complexity. These include:
- Complex systemic disease with skin manifestations, such as sarcoidosis, systemic lupus erythematosus, dermatomyositis, among others.
- Prurigo nodularis.
- Complex systemic drug reactions, such as drug hypersensitivity syndrome or toxic epidermal necrolysis.
- Complex psoriasis or dermatitis, involving more than 30% body surface area, or requiring systemic therapy or prolonged direct patient interaction.
- Complex skin cancer or high risk, including high-risk melanoma, basal cell carcinoma, or patients with extensive actinic keratoses or multiple dysplastic nevi.
Note that a complex dermatology assessment includes all elements of a specific assessment, and the frequency is limited to six times per patient, per physician, within a 12-month period.
4What Your Clinical Note Must Show
Ensure accurate time recording for service validation:
- Record the start and end time of the service in the patient's medical record.
- Exclude time spent on other payable services or non-patient-facing activities.
5Weak vs. Strong Note Examples
The strong note succeeds by explicitly documenting the complexity of the condition and the necessity of systemic management, fulfilling the A020 criteria. The weak note lacks sufficient detail to justify complexity or extensive assessment.
Patient has multiple rashes. Assessed and advised treatment.
Patient presents with severe systemic lupus erythematosus, affecting more than 30% of body surface area. An in-depth assessment was conducted, covering systemic effects and potential treatment with methotrexate. Continued management planned.
- Detailed history including duration of condition and systems involved
- Comprehensive examination findings
- Specific therapeutic plans discussed
