1What Is the C053 OHIP Code?
What is C053?
C053 pertains to medical specific assessments performed by public health and preventive medicine specialists in hospital in-patient settings. These assessments are typically focused on issues like exposure to communicable diseases or immunization queries, focusing solely on the problem presented rather than a full systemic review.
This service requires an in-depth review of the patient’s complaint and a targeted examination of the potentially affected areas. Missing the opportunity to correctly bill this code often involves misunderstanding either the specific patient eligibility scenarios or documentation requirements.

4What Your Clinical Note Must Show
Detailed documentation is crucial for compliance and effective billing of C053.
- Record the start and end time of the service, noting these in the patient's permanent medical record.
- Provide a comprehensive account of the patient's presenting complaint and a detailed examination of the relevant parts or systems.
5Weak vs. Strong Note Examples
The strong note succeeds by providing a comprehensive and detailed record of all aspects of the assessment, including specific symptoms, history, examination, and timekeeping, thereby fulfilling OHIP's documentation requirements.
Patient presented with fever. History taken. Examination done. Time recorded on file.
Patient presented with fever and suspected measles exposure. Full history taken including contact tracing, symptoms onset, and previous vaccinations. A detailed examination of lymph nodes and respiratory system was conducted. Assessment started at 10:00 am and ended at 10:45 am.
- Documented contact history and symptom onset
- Vaccination status noted
- Specific systems examined with clear findings
- Start and end times clearly documented in the file
