California CDPH 110b TB Confidential Morbidity Report

California providers use CDPH 110b only for reporting tuberculosis to the local health department, within one working day. The 1-page fillable form records TB status (active confirmed or suspected, infected with no disease, or converter), site, skin test and IGRA results, imaging, bacteriology, rapid drug resistance, NAAT results and current treatment. Other reportable diseases use CDPH 110a.

Who completes it

The reporting health care provider or facility completes the whole form, including patient demographics, occupational or exposure setting, onset and diagnosis dates, and the reporting provider and laboratory.

Submitting and payment

Who pays
There is no fee to file, and the form has no billing section.

Good to know

  • The form defines a converter as a TST increase of more than 10 mm in induration within less than 2 years.
  • Mark bacteriology positive if any initial smear or culture specimen was positive; pathology suggesting TB has its own checkbox.
  • Treatment status options include untreated, will treat, unable to contact patient, patient refused treatment, or referred elsewhere.
  • The CDPH 8620 RVCT tuberculosis form is completed by the health department, not the reporting provider.
