X185 – Mammogram - bilateral (signs or symptoms)
OHIP Laboratory Code — DIAGNOSTIC RADIOLOGY · Schedule of Benefits
Bilateral mammogram performed with dedicated equipment. This service is intended for diagnostic purposes for individuals who present with signs or symptoms of breast disease, or for the follow-up of previously established disease. This service has both a technical component (H) and a professional component (P). The professional component fee is paid to the physician. As per the commentary on page of the Schedule, this is for: 'individuals with identified signs or symptoms or follow-up of established disease.'
When to Use
- Use X185 for diagnostic bilateral mammography when a patient presents with specific clinical findings such as a palpable breast lump, focal pain, or nipple discharge.
- Use X185 for the surveillance of patients with a previously confirmed breast malignancy or other established breast pathology requiring interval imaging.
- Use X185 rather than screening codes (e.g., X172) when the examination is triggered by a physician-documented clinical concern rather than routine population-based screening.
Common Pitfalls
- Billing X185 for routine screening mammography is a common audit trigger; ensure the medical record explicitly links the service to a specific sign, symptom, or established disease.
- Failure to document the referring physician's name and the clinical indication for the diagnostic study will lead to claim rejection or recovery during an audit.
- Submitting X185 for unilateral studies is incorrect; ensure the clinical necessity for a bilateral study is justified in the report when only one side is symptomatic.
Billing Tips
- Always ensure the diagnostic report includes the specific clinical indication (e.g., 'palpable mass at 2 o'clock') to satisfy the documentation requirements for diagnostic imaging.
- If the patient is under 16, verify if the clinical scenario meets the criteria for the trauma premium (E420) or age-based premiums to maximize the claim value.
