Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $2,613 of the $2,867 with a category attached, or 91.1%. Vifor Pharma, Inc. accounts for 91.1% of it on its own, with 7 other manufacturers making up the rest. 2025 is the largest year on record at $2,648, more than ten times the $19 reported in 2021. Among nurse practitioner clinicians in SD with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 13 payments — averaging $220.52 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$2,867 in reported general payments places this provider in the 90th percentile of 504 nurse practitioner providers in South Dakota.
Medicare billing
What this is not: this is the amount Original Medicare Part B allowed for services this provider billed in 2024. It is not their income. It excludes Medicare Advantage — now more than half of all Medicare enrollment — along with Medicaid and all commercial insurance, and it is gross practice revenue before staff, rent, supplies and malpractice premiums. CMS also suppresses any figure covering ten or fewer patients, so low-volume providers appear smaller than they are.

| Drug | Claims | Cost to plans & patients |

| Ipratropium Bromide | 39 | $822 |
| Levocetirizine Dihydrochloride | 28 | $487 |
| Montelukast Sodium | 65 | $312 |
| Methylprednisolone | 24 | $181 |
