A missing listing does not mean out of network. Directories change, and a listing does not cover every office. Call Dr. Mason’s office at (650) 498-7200 to confirm they take your plan. Ask about the office you use, its medical group, referrals and appointments.

Original Medicare doctor bills

| Screening papanicolaou smear; obtaining, preparing and conveyance of cervical or vaginal smear to laboratory | 13 | $746 | $57 |
Who their Medicare patients are

The office billed $8,694, Medicare allowed $2,851 and paid $2,448; for 41 services of 6 kinds.
Original Medicare patients only. A risk score of 1.0 is the average Medicare patient; higher means sicker. Any count under 11 is hidden.
Year by year
| 2024 | 26 | 41 | 72 | 0.82 | $8,694 | $2,448 |
| 2023 | 24 | 34 | 75 | 0.93 | $7,373 | $1,986 |
| 2022 | 12 | 13 | 73 | 0.83 | $4,719 | $1,286 |
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
$3,971
Pharmacies billed $3,971 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 0% of their Part D prescriptions (0 of 48) in 2024. Too few prescriptions to compare fairly with other clinicians.
37 generic and 11 brand-name prescriptions · $3,971 in drug cost.
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.
