RENA SOMMER, RN appears in the CMS NPPES registry as a Maternal Newborn Registered Nurse provider holding RN credentials at 2008 S WASHINGTON AVE, PARK RIDGE, IL, 60068, with a listed phone of (773) 512-6046. NPI 1740012913 was issued on 08/16/2024. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what SOMMER most recently submitted to CMS rather than a vetted directory listing, which is why patients should always confirm the practice is still at this location before scheduling.

Medicare Part D prescribing data is not currently published for this NPI, which typically means the provider either wrote fewer than 11 Part D claims in the most recent reporting year, does not participate in Medicare, or practices in a specialty that rarely prescribes outpatient drugs. Absence of prescribing data is not a quality signal — many Maternal Newborn Registered Nurse providers operate outside Part D entirely.

Maternal Newborn Registered Nurse is a narrow specialty nationwide, with 811 enrolled providers across 50 states and an average of 290 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline. Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. Inclusion here does not imply a recommendation, and absence of complaints or sanctions on this page does not mean none exist — always verify credentials through the NPPES NPI Registry, your state medical board, and the ABMS or AOA before making healthcare decisions.
