A missing listing does not mean out of network. Directories change, and a listing does not cover every office. Call Dr. Cohn’s office at (415) 600-1020 to confirm they take your plan. Ask about the office you use, its medical group, referrals and appointments.

Drugs they prescribed that Part D paid

$86,441

Pharmacies billed $86,441 in 2024.

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

Opioids were 36% of their Part D prescriptions (201 of 554) in 2024. At or below the middle of the specialty; the typical hospice and palliative care clinician is at 43%. Long-acting opioids: 48% of their opioid prescriptions.

500 generic and 54 brand-name prescriptions · $86,441 in drug cost · 22 antibiotic prescriptions to 14 people · 30 antipsychotic prescriptions to people over 65.

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.
