Authorities in the Dominican Republic are investigating a corruption network accused of defrauding the National Health Insurance (Senasa) through irregular medical authorizations and fraudulent maneuvers. Investigations under Operación Cobra and Cobra 2.0 suggest the scheme may have defrauded the state of billions of pesos.

In the Senasa 2.0-A case, the Second Criminal Chamber of the Court of Appeals of the National District upheld pretrial detention for seven defendants: Angeury Guzmán Vásquez, Juan Henry Poueriet, Wander Manuel Díaz Encarnación, Ysabel Heredia Vallejo, Hanna Rashell Rodríguez Almanzar, Laura Altagracia Santana Evangelista, and Juan Gabriel Rodríguez Ravelo. Elsa Evelyn de la Rosa Vásquez remains under house arrest with electronic monitoring after reportedly admitting to the facts attributed to her. This specific investigation targets an alleged fraud exceeding RD$15,000 million involving identity theft and billing for services never performed.

In a related proceeding, Judge Deiby Timoteo Peguero maintained pretrial detention for former Senasa director Santiago Hazim and four other defendants: Gustavo Enrique Messina Cruz, Germán Rafael Robles Quiñones, Francisco Iván Minaya Pérez, and Ramón Alan Spiekler Mateo. As of November 2026, Hazim, who was dismissed by President Luis Abinader in August 2025, has reached 11 months in preventive detention. He remains at the Las Parras penitentiary complex alongside other implicated individuals, including Eduardo Read Estrella, Cinty Acosta Sención, and Ada Ledesma Ubiera. Rafael Luis Martínez Hazim was granted house arrest with a 15 million peso economic guarantee.
