| Skin & intradermal testing (95004, 95024) | Percutaneous and intracutaneous tests, reported per individual test | Units set to the number of tests performed, held inside each Turquoise Care plan's annual cap and Medicare MUEs, never billed as one panel |
| Antigen preparation (95165) | Supplying multidose-vial extract | Units billed from the mixing log — one cc per dose, ten doses per vial for Medicare — reconciled line by line |
| Immunotherapy administration (95115, 95117) | The injection itself, single vs. multiple | 95117 billed once for two or more injections, never multiplied; paired to the antigen line only when we prepared it |
| Biologics (omalizumab, mepolizumab, benralizumab) | Buy-and-bill drugs for severe asthma and chronic urticaria | HCPCS unit math validated mg by mg, JW/JZ wastage attested, PA confirmed against the plan's PDL before administration |
| E/M plus procedure (modifier 25) | A separately identifiable visit on a testing or injection day | Modifier 25 appended only when a distinct, documented visit stands on its own — never on a scheduled shot |
