Triage: Patient responsibility, switch to cash
The plan visit or dollar cap for the benefit period is exhausted. This is a hard cap, not a judgment call, and it is not appealable the way a frequency denial is.
Chiropractic benefits are frequently capped at a fixed number of visits per year. The cap arriving mid care plan is a front desk moment, not a billing one: the patient needs to know before the next visit, not after three more denials.
A plan allows twenty chiropractic visits per year. The patient uses them by August. Visit twenty one denies PR-119, and so do the next four, because nobody was counting. The patient is now surprised by five visits of balance they never agreed to pay, and the front desk conversation that should have happened in August happens in October, angrier.
Eligibility tracks remaining visits so the cap is visible before it hits, and when a 119 lands anyway the worklist routes it to the cash conversion path instead of a rebill loop.
