The split

2 differences on the record. The others match.

What each puts on the record: Coreage Rx

• Pricing is flat-rate: there is no separate monthly membership stacked on top of the medication price.
• Dose increases within the covered range do not change the price, which is unusual in this market.

Where it wins: The advertised price is the billed price — no membership fee arrives in month two. Watch for: The $99 and $149 rates are annual-plan prices. If you want month-to-month, budget $149 and $199 instead, and check the refund terms before prepaying a year.

What each puts on the record: PlexusDx

• No membership or platform fee is charged alongside the medication.
• Publicly names six 503A pharmacy partners: Belmar, Strive, Epiq Scripts, Casa Pharma Rx, The Pharmacy Hub and Foothills.

Where it wins: The most detailed pharmacy disclosure in this comparison — six named 503A partners. Watch for: The advertised "from $129" is the programme floor. Budget $189/month for the compounded injection tier.

The desk’s call

The board says PlexusDx. What the board cannot say is whether the advertised figures you were shown elsewhere match these — check the gap row, because a listing that advertises low and bills high will beat an honest one in any comparison built on advertised prices.
