Verifying the person but not the company
A valid individual licence does not authorise freelance home visits; the visit must run through a licensed home healthcare provider. Skipping this check is how people end up with undocumented treatment that insurers will not touch and regulators cannot trace. Ask for both licences, every time.
Buying a large package at the first session
Prepaying twenty sessions before anyone has properly assessed you inverts the clinical logic: the treatment plan should determine the session count, not the sales target. Reasonable packages exist, but commit only after the assessment, and prefer arrangements where payment and scheduling are tracked rather than handed over in cash.
Sorting insurance paperwork after treatment instead of before
Insurers reject physiotherapy claims for missing referrals and absent pre-approvals more than for any clinical reason. Reconstructing a referral chain months later, for treatment already delivered, rarely succeeds. Get the referral, the pre-approval reference and properly coded invoices as you go, and keep them together.
