SARA ERGER, APRN appears in the CMS NPPES registry as a Primary Care Nurse Practitioner provider holding APRN credentials at 851 S WILLOW AVE STE 112, COOKEVILLE, TN, 38501, with a listed phone of (615) 941-8501. NPI 1821534314 was issued on 01/09/2017. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ERGER 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 records for calendar year 2023 show 2,539 prescription claims written by this provider, covering 454 Medicare beneficiaries and totaling roughly $171K in drug spend, split 6% brand-name and 94% generic by claim count, with an opioid prescribing rate of 52.9%. These figures capture only Medicare Part D — commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy.

Primary Care Nurse Practitioner is a mid-sized specialty nationwide, with 10,138 enrolled providers across 54 states and an average of 1,363 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
