# Practice model: hybrid and membership

> Mixing insurance, cash-pay, and membership revenue in one practice, what works, and the compliance seams between the models.

Most real practices are hybrids: in-network for some payers, cash for
everything else, maybe a membership plan for the uninsured. Hybrids capture
more revenue but inherit the compliance surface of *every* model they touch,
plus a few seams unique to mixing them.

## The seams to watch

**You can't bill a patient cash for a covered service under a contract that
forbids it.** Participation agreements typically require you to bill the payer
for covered services and limit what you can collect from members. Cash pricing
applies to non-covered services, out-of-network patients, or patients who sign
the payer's version of an advance notice (Medicare's ABN being the canonical
one). **Your cash price also talks to your fee schedule**, payers may audit
against "usual and customary," and a cash price below a contracted rate
invites repricing arguments. **Membership plans for insured patients** must be
built from things insurance doesn't cover, or they collide with both the
payer contract and state prepaid-plan rules (see
[cash-pay model](/concepts/practice-models-cash-pay)).

## Operationally

Run one ledger with clear revenue classes (insurance, patient
responsibility, cash service, membership), settle card revenue and payer EFTs
into identifiable accounts
([account structure](/concepts/practice-banking-structure)), and reconcile the
two streams separately, insurance by
[ERA](/concepts/era-vs-eob), cash by processor settlement report.
