A missing listing does not mean out of network. Directories change, and a listing does not cover every office. Call Dr. Howlett’s office at (415) 476-1000 to confirm they take your plan. Ask about the office you use, its medical group, referrals and appointments.

Scores the office’s reporting and systems. It is not a grade for how the doctor treats you.

Original Medicare doctor bills

$18,727

Medicare paid this office $18,727 for 106 people.

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

Short return visit (20+ min)24$1,726$52

Times billed to Original Medicare each year. A blank year means fewer than 11 people had it, or none: Medicare does not publish smaller counts. Medicare Advantage patients are not included.

Who their Medicare patients are

106 Original Medicare patients in 2024. Average age 71 · Women 77% · Also on Medicaid 80% · Health risk score 1.82. Above the middle of the specialty; the typical internal medicine clinician is at 1.76.

Conditions among them: High blood pressure 75% · Diabetes 42% · Chronic kidney disease 29% · Depression 23% · Coronary heart disease 21% · Heart failure 21% · COPD 12% · Stroke 12% · Cancer 11% · Atrial fibrillation 11%.

The office billed $182,271, Medicare allowed $26,863 and paid $18,727; for 259 services of 12 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.

Medicaid work

$3,675 in 2024

Medicaid paid $3,675 for 2,398 billed services this clinician did in 2024, up to 84 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

$1,301,542

Pharmacies billed $1,301,542 in 2024.

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

Opioids were 6% of their Part D prescriptions (56 of 986) in 2024. Above the middle of the specialty; the typical internal medicine clinician is at 1%.

750 generic and 236 brand-name prescriptions · $1,301,542 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.
