A missing listing does not mean out of network. Directories change, and a listing does not cover every office. Call Dr. Ang’s office at (408) 241-3801 to confirm they take your plan. Ask about the office you use, its medical group, referrals and appointments.

Year by year
| 2024 | 194 | 408 | 75 | 0.97 | $123,989 | $45,800 |
| 2023 | 17 | 23 | 77 | 1.06 | $7,497 | $2,547 |
Original Medicare only. A service billed for fewer than 11 people in a year is hidden, so the lines can add up to less than the year's total.
Drugs they prescribed that Part D paid
$96,592
Pharmacies billed $96,592 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
951 generic and fewer than 11 brand-name prescriptions · $96,592 in drug cost · 40 antibiotic prescriptions to 34 people.
Part D prescriptions only. The opioid rate is opioid prescriptions as a share of all this clinician's Part D prescriptions; surgeons and pain specialists run higher than others, so it is shown against the same specialty.
