1What Is the C020 OHIP Code?
C020 is an OHIP billing code used by dermatologists for providing complex dermatology assessments for non-emergency hospital in-patients. This service involves a thorough evaluation of patients with severe cutaneous conditions that require ongoing management due to their systemic nature or integration with other significant health issues.
Such assessments are crucial in cases like sarcoidosis with skin manifestations, systemic lupus erythematosus, or complex skin cancers, where the dermatologist's expertise in assessing the whole skin surface and related systemic symptoms is essential. Given the complexity and the specialized care involved, this code is utilized when the needs of the patient extend beyond a routine dermatological exam.
C020 assessments can often be missed when the specific systemic conditions or criteria, such as extensive body surface area involvement, are not adequately documented or communicated. Proper understanding of the eligibility requirements can help ensure that this billing code is correctly applied.

3Eligibility Requirements
To bill C020, the patient must be a non-emergency hospital in-patient requiring complex dermatology assessments due to:
- Complex systemic disease with specific skin manifestations (e.g., sarcoidosis, systemic lupus erythematosus, dermatomyositis).
- Prurigo nodularis.
- Complex systemic drug reactions (e.g., drug hypersensitivity syndrome, toxic epidermal necrolysis).
- "Complex psoriasis" or "complex dermatitis" involving more than 30% of body surface area or requiring systemic therapy.
- Complex skin cancer or high risk of developing skin cancer as specified by high-risk criteria.
The service is subject to a maximum of 6 assessments per patient, per physician, per 12-month period, and must include all elements of a specific assessment.
4What Your Clinical Note Must Show
Record the exact time when the service started and ended
- Document duration of patient interaction

5Weak vs. Strong Note Examples
The strong note clearly articulates the systemic condition, links it explicitly to skin manifestations, and details the management plan, all requirements for billing C020. The weak note lacks specific detail and justification for the complex assessment.
Patient evaluated for skin rash. Temporary treatment plan provided. Follow-up scheduled.
Patient with extensive systemic lupus erythematosus presented with significant skin involvement (>30% body surface area). Detailed examination conducted, confirming erythematous plaques consistent with known disease. Commenced systemic therapy with methotrexate. Immediate follow-up is essential.
- Documented specific systemic condition
- Described detailed skin examination
- Initiated and documented systemic treatment
