Jessica Chang, MD appears in the CMS NPPES registry as a Ophthalmology Physician provider holding MD credentials at 1450 SAN PABLO ST FL 4, Los Angeles, CA, 90033, with a listed phone of (323) 442-6335. NPI 1245527860 was issued on 07/04/2011. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Chang 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 422 prescription claims written by this provider, covering 161 Medicare beneficiaries and totaling roughly $28K in drug spend, split 25% brand-name and 75% generic by claim count, with an opioid prescribing rate of 5.5%. 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.

Ophthalmology Physician is a mid-sized specialty nationwide, with 22,090 enrolled providers across 56 states and an average of 1,420 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
