BOC-CDME common mistakes
BOC-CDME · Understand the traps and how to avoid them.
Coding a claim from the physician's order alone without confirming that the written order, the proof of delivery, and the itemized dispensing record all match on item, quantity, and date.
Candidates treat the order as the single source of truth and assume documentation elsewhere is clerical, so they stop auditing once the order looks complete.
What to do instead
Before finalizing any claim, reconcile four documents line by line: the detailed written order, the delivery receipt (with recipient signature and date), the itemized invoice, and the chart note establishing medical necessity. Flag any mismatch and resolve it before submission.
Submitting claims with a missing or vague detailed written order, such as one that says only 'wheelchair' without specifying the base type, seat width, or accessories.
Candidates underestimate how specific the order must be and assume the supplier's product selection can fill in the gaps.
What to do instead
Build a checklist of required order elements for each equipment category (item description, features, quantity, length of need, treating practitioner signature and date) and verify each element is present and specific before billing.
Confusing rental versus purchase billing rules, such as billing a capped rental item as a lump-sum purchase or continuing rental past the capped period.
Candidates memorize payment amounts without mapping them to the correct payment methodology for each HCPCS code.
What to do instead
Maintain a code-by-code reference table showing payment category (purchase, capped rental, oxygen, etc.), and practice classifying unfamiliar codes by category before calculating any reimbursement.
Selecting a HCPCS code by product marketing name or by what the referral says rather than by the code descriptor and coverage criteria.
Brand familiarity and referral shorthand feel authoritative, so candidates skip the descriptor verification step.
What to do instead
Always read the full HCPCS long descriptor and the applicable local coverage determination before assigning a code; when two codes seem plausible, document the clinical features that justify the chosen one.
Recommending or dispensing an item without verifying that it fits the patient's functional level and the payer's coverage criteria, for example supplying a power mobility device without a mobility evaluation.
Candidates focus on the equipment's features and the patient's stated preference instead of the clinical eligibility pathway.
What to do instead
For each equipment category, write out the eligibility prerequisites (face-to-face exam, mobility evaluation, trial, practitioner attestation) and confirm each is satisfied and documented before the item is ordered.
Treating a beneficiary's verbal assurance of coverage as sufficient and skipping verification of eligibility, deductible status, or prior authorization requirements.
Candidates want to help the patient quickly and view intake paperwork as a formality rather than a financial control.
What to do instead
Adopt a mandatory intake sequence: verify eligibility and benefits, check deductible and coinsurance, confirm prior authorization needs, and obtain a signed advance beneficiary notice where coverage is questionable, all before delivery.
Failing to maintain or reconcile inventory and serial-number records, so equipment cannot be traced to a specific patient or delivery.
Candidates see inventory as a warehouse task unrelated to billing and compliance, so they do not connect serial numbers to claims and proof of delivery.
What to do instead
Practice linking each dispensed device's serial number to the patient record, delivery date, and claim, and review how a missing serial number undermines both an audit and a warranty claim.
Billing for an item before the required documentation exists, or backdating or altering records to make the file look complete.
Candidates feel pressure to meet timely-filing deadlines and see documentation as a downstream step rather than a precondition.
What to do instead
Internalize the rule that the claim follows the documentation, never the reverse; when documentation is incomplete, hold the claim, correct the record prospectively with a dated addendum, and never alter a prior entry.
Offering or accepting improper inducements, such as waiving coinsurance routinely or giving free equipment to referral sources, without recognizing the compliance problem.
Candidates view waivers and gifts as customer service or marketing rather than as potential violations of fraud and abuse rules.
What to do instead
Study the anti-kickback and beneficiary-inducement principles, then apply a routine test to every discount or gift: is it required by a documented financial hardship policy, offered uniformly, and not tied to referrals?
Handling a patient complaint or equipment problem by promising a replacement or refund without documenting the interaction, troubleshooting step, or resolution.
Candidates prioritize the immediate interpersonal fix and treat recordkeeping as optional once the patient seems satisfied.
What to do instead
Use a standard service-recovery format for every patient contact: record the concern, the troubleshooting or education provided, the outcome, and any follow-up date, and confirm the patient's understanding before closing the record.
