LISA MAILLIARD appears in the CMS NPPES registry as a Gerontology Clinical Nurse Specialist provider at 5841 S MARYLAND AVE, CHICAGO, IL, 60637, with a listed phone of (888) 824-0200. NPI 1861514820 was issued on 04/03/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MAILLIARD 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 1,669 prescription claims written by this provider, covering 397 Medicare beneficiaries and totaling roughly $123K in drug spend, split 13% brand-name and 87% generic by claim count, with an opioid prescribing rate of 2.5%. 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. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 97.7188/100 for the 2023 performance year (Quality 75.4375), compared with the national average of 83.1.

Gerontology Clinical Nurse Specialist is a narrow specialty nationwide, with 393 enrolled providers across 47 states and an average of 906 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
