1What Is the W255 OHIP Code?
Definition and Clinical Context
The W255 billing code is designated for limited endocrinology consultations in non-emergency, long-term care settings such as nursing homes or chronic care hospitals in Ontario. This type of consultation typically involves addressing a single focused clinical question related to an endocrinological condition, such as interpreting an abnormal thyroid test or simplifying an insulin regimen for a frail resident.
Why W255 is Often Missed
Due to its specificity, the W255 code may be overlooked by practitioners who might default to more general consultation codes. Understanding the clinical context and eligibility requirements is essential to ensure accurate billing and maximize consultative services offered to long-term care patients.

3Eligibility Requirements
Eligibility Requirements
According to the OHIP Schedule of Benefits, the W255 code is applicable for non-emergency long-term care in-patient services, including chronic care hospitals, convalescent hospitals, nursing homes, and homes for the aged. Note that patients in designated palliative care beds are excluded. An eligible consultation must be preceded by a written request from a referring physician, nurse practitioner, or dental surgeon related to an insured dental procedure in a hospital. The limited consultation must meet the requirements outlined in the General Preamble (GP16, GP17, GP19).
4What Your Clinical Note Must Show
Ensure the following documentation is included in the patient's medical record:
- A written referral request from a qualifying referring provider (physician, nurse practitioner, or dental surgeon).
- Detailed notes on the focused clinical question addressed during the consultation.
- Explanation of the consultation's limited scope in comparison to a full consultation.
- Patient history relevant to the endocrinology issue at hand.
5Weak vs. Strong Note Examples
The strong note succeeds by clearly documenting the focused issue discussed and actions taken, showcasing thorough patient evaluation and appropriate adjustments. The weak note lacks detailed justification and specificity.
Consulted on thyroid levels. Adjusted medication.
Reviewed insulin regimen briefly.
Limited endocrinology consultation per W255 request: Reviewed patient's recent abnormal thyroid test results due to ongoing fatigue and weight changes.
Decided to adjust TSH suppression therapy. Explained to LTC staff the rationale behind modifying the insulin regimen based on the resident's declining mobility and recent hypoglycemic episodes.
- Referral from Dr. Smith, noted problems with recent lab results.
- Focused assessment: TSH level 0.01, patient exhibits fatigue and weight change.
- Consultation details: Adjusted levothyroxine dosage, established follow-up with attending nurse.
