Cal. Civ. Code § 460.040
Mandatory Reporting
Operative Text
(A) Physicians, other health care providers, and state and private laboratories shall report to the
Director all cases known by them of childhood lead poisoning of Massachusetts residents within three
working days of identification, unless previously reported. Should a child suffer multiple episodes of
lead poisoning, each episode must be reported.
(B) Laboratories and health care provider practices that analyze blood specimens drawn pursuant to
105 CMR 460.050 for lead or lead and erythrocyte protoporphyrin shall report all results to the State
Program in a secure electronic format approved by the Director. Such reports shall be made within
one week of the analysis. The Director may temporarily waive the electronic reporting requirement for
laboratories or health care provider practices that report only a small volume of results.Under 105 Mass. Code Regs. 460.040, Massachusetts law requires physicians, other health care providers, and laboratories to report every confirmed case of childhood lead poisoning to the state Director within three working days of identification. If a child experiences more than one episode of lead poisoning, each episode must be reported separately. Laboratories and health care practices that test blood specimens for lead must also submit all results electronically to the State Program within one week of analysis, though the Director may grant a temporary waiver of the electronic format requirement for low-volume reporters.
Plain English — not legal advice.
While 105 Mass. Code Regs. 460.040 places reporting duties on health care providers and laboratories rather than property owners directly, landlords should understand that this mandatory reporting system means lead poisoning cases involving children in their units are likely to come to the attention of state authorities quickly. Compliant property operators generally maintain lead-safe conditions and keep required lead inspection and remediation records current so they are prepared to respond if a case is reported. Familiarity with this reporting framework helps property managers understand how state oversight of childhood lead exposure is triggered.

Section 105 Mass. Code Regs. 460.040 establishes that if a child is diagnosed with lead poisoning, the diagnosing physician or laboratory is legally required to report that finding to the state Director within three working days. Tenants whose children have been tested for lead can expect that results are transmitted to the Massachusetts State Program, which may prompt follow-up inspections or remediation requirements at their residence. Tenant-rights organizations and local health departments can help tenants understand what state actions may follow a reported case and what housing protections may be available to them.
