OPC Orthotics Written common mistakes
OPC Orthotics Written · Understand the traps and how to avoid them.
Writing a treatment plan that lists a device (e.g., 'AFO for drop foot') without first documenting the assessment findings, functional deficits, and goals that justify it.
Candidates treat the plan as a product recommendation and skip the clinical reasoning chain, because the device is the most salient part of the case.
What to do instead
Before naming any device, write one sentence each for: assessment findings, functional limitation, measurable goal, and then the device/design that addresses it. If a sentence is missing, the plan is incomplete.
Recording range of motion, strength, or sensation as 'WNL' or 'decreased' instead of specific measured values with the method used.
Time pressure and habit from clinical shorthand lead to vague documentation that cannot support later justification or follow-up comparison.
What to do instead
For every measurement, record the value, units, side, and method (e.g., 'left ankle dorsiflexion 0 degrees with knee extended, measured goniometer, supine'). Replace any 'WNL' with the actual finding.
Failing to verify and document the specific payer requirements (prior authorization, documentation elements, covered codes) before finalizing the treatment plan.
Candidates focus on the clinical case and assume reimbursement is someone else's job, or they conflate Medicare and private-payer rules.
What to do instead
Add a plan step that names the payer, the authorization status, and the documentation elements required. If unknown, state it as an action item rather than omitting it.
Drafting a plan with no measurable, time-bound functional goals, using only impairment-level language like 'improve gait'.
Impairment language feels clinical and safe, but candidates have not practiced converting findings into activity-level, measurable outcomes.
What to do instead
Write each goal as activity + measurable criterion + timeframe (e.g., 'walk 150 m without resting in 6 weeks'). Reject any goal that cannot be scored pass/fail.
Skipping or superficially documenting the follow-up assessment, recording only 'patient doing well' without objective comparison to baseline.
Follow-up is seen as a formality, and candidates do not rehearse re-measurement of the same variables used at baseline.
What to do instead
At follow-up, re-measure the exact baseline variables and state change explicitly (better/same/worse with numbers), plus device fit, skin integrity, and adherence.
Making a device modification or adjustment without documenting the rationale, the change made, and the patient's response.
Adjustments feel routine and are done quickly in clinic, so the reasoning and outcome go unrecorded.
What to do instead
For every adjustment, record: problem observed, change made, and immediate patient response. Treat it as a mini clinical note, not a work order.
Answering ethics items by choosing the option that protects the practitioner or the business rather than applying the specific Canon of Ethical Conduct implicated.
Candidates reason from general 'be professional' instinct instead of identifying which canon (e.g., competence, integrity, confidentiality, conflict of interest) governs the scenario.
What to do instead
Name the canon first, then select the action that satisfies it. If two options both seem ethical, choose the one with the greater transparency and disclosure obligation.
Treating a conflict-of-interest or gift/ referral scenario as harmless because no explicit payment changed hands.
Candidates underestimate indirect inducements and assume ethics only concerns overt fraud.
What to do instead
Apply the disclosure test: if the relationship would need to be disclosed to the patient or payer to be acceptable, it likely must be avoided or disclosed in writing.
Designing the orthosis from a single assessment finding (e.g., one muscle grade) without integrating tone, sensation, skin condition, body habitus, and patient goals.
Candidates anchor on the most dramatic finding and stop gathering data, a classic premature-closure error.
What to do instead
Use a fixed checklist (ROM, strength, tone, sensation, skin, vascular, cognition, goals, environment) and confirm each item is addressed before selecting a design.
Omitting patient education, expected wear schedule, skin-check instructions, and warning signs from the implementation or follow-up plan.
Candidates equate implementation with fabrication and delivery, and forget that adherence and safety depend on documented instruction.
What to do instead
Include an explicit education section: wear schedule, donning/doffing, skin checks, warning signs, and when to call. Document that the patient/caregiver demonstrated understanding.
