Required - Assessment using WHODAS 2.0 (effective October 23, 2015)

  • Use the 12-item WHODAS 2.0 at baseline and every 30 days to track and document the worker’s functional status.
  • The 36-item WHODAS 2.0 is also acceptable. (Due to scoring differentials, the provider must consistently use the same WHODAS 2.0 instrument.)
  • Score using the 0–4 method, described in the scoring templates on the WHODAS website. 
  • Include the WHODAS 2.0 results in required reports or comprehensive chart notes. Explain what the numerical results mean (submit a copy of the completed and scored form).
    • For the initial WHODAS 2.0, indicate the domain(s) impacted by the mental health condition and how treatment will be directed to improve these areas.
    • For subsequent WHODAS 2.0 results, describe the trend in the scores as they relate to the injured worker’s progress in attaining the identified goals.
