* Product-associated amounts are non-additive because one payment record may name more than one product.

These products were named on specific Open Payments records. A named product does not show that the payment influenced treatment or prescribing.

Public prescribing for products named in payments

Open Payments product	Payment year	Part D brand	Part D year	Claims	Match method	Source
CREON creon	2025	Creon	2024	883	exact normalized	Medicare Part D
LINZESS linzess	2025	Linzess	2024	342	exact normalized	Medicare Part D

The presence of the same drug in both datasets does not show that a payment caused or influenced a prescription.

Analysis 2 · Same-company prescribing overlap

Drugs reported in other payments from the same company that also appear in Medicare Part D

This analysis is independent from products named on this doctor’s individual payment records. A row appears only when the exact Open Payments reporting entity paid this doctor, that same reporting entity reported the drug or biological on at least 10 loaded General Payment records involving at least 2 distinct recipient NPIs, and this doctor has the same non-generic brand in public Part D data. This does not mean the company owns or manufactures the drug.

Paying company	Payment year	Drug reported by same entity	Open Payments evidence	Part D	Claims	Beneficiaries
ABBVIE INC. Exact reporting entity; no affiliate inference	2025	CREON open payments reported associated product	CMS Open Payments — General Payments 91561 supporting records · 20616 recipient NPIs · example record 1201352608	Creon · 2024 Exact normalized brand match · 1 Part D row	883	251

These facts do not show that a payment was for the drug, that the company owns or manufactures the drug, or that a payment caused or influenced prescribing.

Questions to ask

Questions you could discuss with your doctor

What role, if any, does Creon play in your treatment recommendations for me?
How do you evaluate evidence when you have a financial relationship with ABBVIE INC.?
Are there reasonable alternatives I should understand when we discuss treatment options?
How should I interpret the industry-payment records shown here in the context of my care?

These are general questions generated from reviewed templates. They are not personalized medical advice.

Sources and limitations

How to read this page

Payment and Medicare prescribing data can cover different years; every comparison shows both years explicitly.
Part D does not represent a doctor’s entire practice; it excludes many patients and is subject to CMS public-release thresholds.
Company–drug relationships must have an auditable source, a precise relationship type, and a valid evidence period. Unresolved mappings are not published.
Generic drug claims are not attributed to a specific manufacturer without manufacturer-level evidence.
When a source extract is incomplete, missing rows are never treated as proof of no payments or no prescriptions.
