Frequently Asked Questions
What is the difference between BOC COF and ABC CO?
BOC COF (Certified Orthotic Fitter) fits OFF-THE-SHELF and custom-fitted orthoses but does NOT custom-fabricate. ABC CO (Certified Orthotist) is a higher-credential clinician who assesses patients and designs CUSTOM-FABRICATED orthoses (lamination, vacuum forming, modified positives). Both can bill Medicare for fittings; only the CO can bill for custom-fab L-codes.
What is included in a Standard Written Order (SWO)?
Since 2020, Medicare requires a Standard Written Order (SWO) replacing legacy DWO/CMN forms. SWO must include: patient name; date of order; description of items ordered; quantity; ordering practitioner name + NPI; ordering practitioner signature + date. Face-to-face encounter required within 6 months for many DMEPOS items. Detailed medical record support remains essential.
What is an ABN and when is it issued?
ABN = Advance Beneficiary Notice of Noncoverage (Form CMS-R-131). Given to a Medicare beneficiary BEFORE providing an item that may not be covered (frequency limit, not medically necessary, exceeds Medicare coverage). The ABN allows the supplier to bill the patient if Medicare denies. Modifier GA appended to the claim indicates ABN is on file. Without ABN + GA, supplier bears the cost.
How should I study for BOC COF?
Plan 40-80 hours over 6-10 weeks. Focus weighted study on Fitting/Dispensing (30%) and Assessment (20%) — together half the exam. Master the major OTS orthoses (cervical, knee, lumbar, walker boot, wrist), HCPCS L-codes commonly fit, Medicare documentation requirements (SWO, ABN), and BOC scope. Hands-on fitting practice in a DME setting reinforces written content.
