Humana is distinctive for its Medicare Advantage concentration: MA is the core of its business rather than an adjacent line. It also operates CenterWell, a care delivery arm. For most practices, engaging with Humana means engaging with Medicare Advantage operations. Treat this page as orientation; payer’s change their habits often and without notice.

Who they are

Plan types on the card

Humana Gold Plus (HMO), Humana Choice (PPO), and other Medicare Advantage products; dual eligible special needs plans; Medicaid in some states; and a smaller commercial book.

Enrollment and credentialing

Start at provider.humana.com. Many transactions run through Availity. Credentialing generally pulls from CAQH.

EDI, ERA, and EFT

Standard three-part enrollment.

Appeals

Medicare Advantage appeals follow the federal MA appeals track, not a commercial process. The levels, deadlines, and independent review mechanisms differ from commercial appeals, and MA plans are not bound by Medicare fee-for-service’s 12-month timely filing limit. Their filing limits are contractual and frequently much shorter. See Medicare Advantage.

Quirks worth knowing

  • Prior authorization requirements are extensive on MA products: this is one of the more auth-heavy payers
  • Risk adjustment and documentation matter more here than with most commercial payers, given the MA model
  • CenterWell operates as a care delivery competitor in some markets
