House Bill No. by Representative Melerine enacts R.S. 23:1172.3, which establishes new regulations regarding the recovery of past payments of workers' compensation premiums. The bill prohibits insurers from recovering past due payments related to employee misclassification claims unless they provide written notice to the insured within ninety days of completing a payroll audit. Additionally, if an insurer conducts a payroll audit, they are barred from collecting additional premiums from the insured. The bill also stipulates that insurers cannot modify or complete a payroll audit more than three years after the policy period ends, with certain exceptions for misrepresentation, noncompliance, disputes, fraud investigations, and court determinations.

Furthermore, the bill clarifies that insurers are not required to return premiums to the insured if they receive relevant information after the audit is completed, and it specifies that the provisions do not apply to self-insurance funds. This legislation aims to enhance transparency and fairness in the workers' compensation system by ensuring timely communication and limiting the timeframe for premium adjustments.
