A missing listing does not mean out of network. Directories change, and a listing does not cover every office. Call Dr. Johnson’s office at (650) 691-6174 to confirm they take your plan. Ask about the office you use, its medical group, referrals and appointments.

Original Medicare doctor bills

$33,978

This is what Medicare paid the clinician — not Medicare Advantage, and not the pharmacy.

Who their Medicare patients are

The office billed $117,746, Medicare allowed $44,764 and paid $33,978; for 902 services of 14 kinds; $1,333 of it was for drugs given in the office and $32,645 for care.

Original Medicare patients only. A risk score of 1.0 is the average Medicare patient; higher means sicker. Any count under 11 is hidden.

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.

Medicaid work

$0 in 2022

Medicaid paid $0 for 27 billed services this clinician did in 2022, up to 14 people in a month for one service.

Medicaid and CHIP claims where this clinician did the service, fee-for-service and managed care together. Any month with fewer than 11 patients is hidden, so small Medicaid practices undercount.

Drugs they prescribed that Part D paid

$243,049

Pharmacies billed $243,049 in 2024.

This is pharmacy cost, not the office bill, and not what patients paid.

Opioids were 3% of their Part D prescriptions (14 of 566) in 2024. At or below the middle of the specialty; the typical rheumatology clinician is at 3%.

517 generic and 49 brand-name prescriptions · $243,049 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.
