The California Department of Public Health (CDPH) has revised its guidelines on what cases of Parkinson’s disease must be reported to https://hie.cdph.ca.gov by physicians beginning July 1, in response to concerns from the California Medical Association (CMA) and others. Among the changes are limiting reportable ICD-10 codes to patient encounters for diagnosis or treatment of Parkinson’s disease occurring on or after July 1; excluding ancillary encounters (e.g., lab imaging); and extending the reporting compliance date from 90 to 180 days through September 30. The revised Implementation Guide is at www.cdph.ca.gov/parkinsons. For more information, go to http://www.cmanet.org/news/detail/?article=cdph-revises-guidance-on-parkinsons-reporting.
