Dataset Methodology & CMS Source Information

This analytical profile maps public infrastructure records sourced directly from official **Centers for Medicare & Medicaid Services (CMS)** public data releases. The statistics above track documented pharmaceutical treatment trends assigned to beneficiaries specifically under federal public programs. Evaluating the prescriptive footprints of clinical practitioners like LAM PHUNG MD provides transparency into local medical care patterns within Fullerton, CA.

Key Learning Objectives for this Profile:

  • Prescribing Frequencies: Track and evaluate the volume metrics of specific brand-name and generic medical formulas chosen by this provider over time.
  • Clinical Focus Areas: Identify how the provider distributes therapeutic selections across medical care options to gain insight into their true day-to-day **Ophthalmology** practice concentrations.
  • Program Cost Awareness: Review the calculated total systemic drug costs and raw transactional volumes linked to these orders to better anticipate network insurance coverage structures.
  • Patient-Centered Evaluation: Cross-reference localized regional care comparisons to align practitioner habits directly with your proactive health maintenance goals.

Data Scope Exclusion & Limitations: The data elements presented above explicitly reflect prescription orders processed for Medicare beneficiaries during the year 2023. This informational profile does not aggregate prescription data for individuals utilizing private commercial health plans, state Medicaid coverage, or self-pay options.
