How a presumption works

Normally an injured worker has to prove the injury came from work. Under a §3212-series presumption, if you're in a covered job and the condition develops or shows up while you're in service, the law presumes it arose out of your employment. The employer can "controvert" it with other evidence, but unless it does, the Workers' Compensation Appeals Board must find in your favor (that is the wording of Labor Code §3212). For heart trouble, hernia and pneumonia under §3212, the law adds that the condition can never be blamed on a disease that existed before it developed or showed up.

The insurer also has less time to decide. For injuries under §§3212 to 3212.85 and §§3212.9 to 3213.2, a claim not denied within 75 days of filing the claim form is presumed compensable, instead of the usual 90 (Labor Code §5402).

The main presumptions

• Hernia, heart trouble and pneumonia, §3212: members of sheriff's offices, the CHP, district attorney inspectors and investigators, city, county and district police and fire departments, active CAL FIRE firefighters, county forestry and fire units, and Fish and Wildlife wardens, excluding those whose main duties are clerical.
• Heart trouble and pneumonia, §3212.5: full-time salaried city police, CHP members, sheriffs and deputies, and DA inspectors and investigators.
• Cancer, including leukemia, Labor Code §3212.1: active firefighters of public fire departments (city, county, district, UC and CSU, CAL FIRE, county forestry and others listed), certain peace officers primarily in active law enforcement, and Cal OES fire and rescue coordinators. You must show you were exposed in service to a known carcinogen, as defined by the International Agency for Research on Cancer or the DIR director. The employer can rebut the presumption only with evidence that the cancer's primary site is established and the carcinogen you were exposed to is not reasonably linked to it. For injuries on or after January 1, 2026, the section also covers certain firefighters at Department of Defense and NASA installations and at FAA-regulated commercial airports.
• Post-traumatic stress disorder, Labor Code §3212.15: covered firefighters and peace officers for injuries on or after January 1, 2020, with PTSD diagnosed under the current DSM. It requires at least six months of service (not necessarily continuous) unless the PTSD was caused by a sudden and extraordinary employment condition. As currently written, the section stays in effect until January 1, 2029.
• Tuberculosis, Labor Code §3212.6: police, sheriffs, CHP, DA investigators, prison and jail guards and correctional officers, and paid firefighters.
• Blood-borne infectious disease and MRSA skin infection, Labor Code §3212.8: sheriff's office, police and fire department members, peace officers, and CAL FIRE and county firefighters, excluding clerical staff.
• Meningitis, Labor Code §3212.9: police, sheriffs, CHP, county probation officers, DA investigators and full-time firefighters.
• Corrections peace officers, Labor Code §3212.10: heart trouble, pneumonia, tuberculosis and meningitis for state corrections peace officers with custodial or supervisory duties over inmates or parolees, and certain local corrections officers.
• Lower back impairment, Labor Code §3213.2: police, sheriff's, CHP and UC peace officers who have worked at least five years full time and were required to wear a duty belt.
• Others: skin cancer for public lifeguards (Labor Code §3212.11), Lyme disease for certain peace officers and California Conservation Corps workers (Labor Code §3212.12), illness from exposure to a biochemical substance for peace officers and firefighters (Labor Code §3212.85), and heart-trouble presumptions for some other state classifications (§§3212.2, 3212.3, 3212.4 and 3212.7).

Each section has its own list of covered classifications and conditions. Whether you're covered depends on your exact job and agency, so read the section itself or ask DWC Information & Assistance.

Coverage after you retire or leave

Most of these presumptions extend past your last day of work: three calendar months for each full year of covered service, counted from the last date you actually worked in that capacity. The cap is 60 months for most of them (§§3212, 3212.5, 3212.6, 3212.9, 3212.10, 3212.15, 3213.2 and others) and 120 months for cancer under §3212.1. For example, a firefighter with 20 full years of service has 60 months (20 × 3) for cancer. A firefighter with 30 years has 90 months for cancer, but only 60 months for heart trouble. The blood-borne disease presumption in §3212.8 has its own, shorter extension rules, so check the section.

Benefits and pay

An accepted presumption claim gets the full range of benefits: medical treatment, disability pay, and death benefits for dependents. Many local public-safety officers receive their full salary instead of temporary disability for up to one year (Labor Code §4850). If a covered worker dies from a presumed condition, see death benefits.

When the employer fights the presumption

• Cancer: disputes focus on exposure (which carcinogens, how often) and whether the cancer type is linked to them. Keep records of fires, hazmat calls and exposure reports.
• Heart and lung: the employer may point to smoking, weight or family history. Under §3212, heart trouble that develops in service can't be attributed to a disease that existed before.
• PTSD: the six-month service rule and the diagnosis itself are the usual issues. For other psychiatric claims, see psychiatric injury claims.
• Disputes are usually resolved with a QME or AME report and, if needed, at the WCAB.

Deadlines still apply

A presumption doesn't extend the time to file. Report the condition, file a DWC-1, and keep the one-year limit in mind (see one-year deadline). For occupational diseases, the clock usually starts when you first had disability and knew or should have known it was work-related (Labor Code §5412).
