In a US practice, a large part of the billing coordinator's day is eligibility and benefits: calling or checking portals to confirm what a plan covers before treatment, then preparing claims with CDT codes and attachments, then working the rejections. In the UK the paperwork is NHS dental claims and plan providers; in Spain, the mutuas and their own authorisation rules. The shape is the same everywhere: structured data scattered across portals, PDFs and phone calls.
Clinic billing automation is useful there, and risky in one specific way. Coding has to reflect what was done and documented. A system that nudges codes towards what pays better is a compliance problem, not an efficiency, so ours checks claims against the notes and flags gaps for a person; it does not optimise reimbursement.
