A Bronx nursing home allegedly paid a hospital social worker to steer elderly patients its way, The Post has learned.

Ex-Kingsbridge Care Center CEO Helen Sieger gave New York Presbyterian’s Frank Rivera nearly $20,000, Attorney General Andrew Cuomo said.

Sieger, 55, allegedly paid $300 per referral and a $1,000 bonus for every 10, and improperly billed Medicaid $1.25 million. She and Kingsbridge are charged with grand larceny.
