WSIB Form 8S (0407A): Occupational Chest Disease

The WSIB sends out this physician's report when a patient reports a work-related occupational chest illness; you complete it and return it to the WSIB. Conditions adjudicated in its Occupational Disease and Survivor Benefits Program include pneumoconiosis, such as asbestosis, silicosis and talcosis, and respiratory disorders such as asthma, COPD and hypersensitivity pneumonitis. The WSIB supplies the form rather than posting it for download.

Who completes it

The physician completes the whole form. The worker's claim (Form 6) and the employer's report (Form 7) are filed separately, and the WSIB may ask the worker to sign a permission form so it can obtain a specialist's report.

Submitting and payment

How to submit it
Complete the copy the WSIB supplies and return it to the WSIB; if you fax it, the physician fee schedule says not to also send the original.
Who pays
Bill the WSIB directly under physician fee code M656, the code for the physician's report on occupational chest disease.

  • Pneumoconiosis claims (asbestosis, silicosis, and talcosis from talc exposure) and all cancers are also adjudicated in the WSIB's Occupational Disease and Survivor Benefits Program.
  • For permanent impairment from work-related asthma, WSIB policy 16-01-01 says the WSIB itself arranges all pulmonary function and histamine or methacholine challenge tests.
