NHA CMAA common mistakes
NHA CMAA · Understand the traps and how to avoid them.
Treats copayment, coinsurance, and deductible as if they were the same thing when calculating what a patient owes at check-in - for example, collecting a flat $25 'copay' from a patient whose plan actually applies 20% coinsurance after a deductible.
The three terms are usually memorized as one-word definitions instead of as a decision sequence, so under time pressure the candidate grabs whichever cost-sharing word appears in the question stem first.
What to do instead
Build a one-page comparison chart keyed to the question each term answers. Copay: 'Is there a fixed dollar amount printed on the card?' Coinsurance: 'What percentage of the allowed amount does the patient pay after the deductible is satisfied?' Deductible: 'How much must the patient pay before the plan begins paying?' Then work three numeric scenarios until the sequence (allowed amount, then deductible, then coinsurance, then copay) is automatic.
Selects the first procedure code whose short description looks similar to the service performed and submits the claim without confirming medical necessity, the full code descriptor, or whether a modifier is required.
Candidates treat coding as a lookup exercise rather than a rule-application exercise, and they have not internalized that the full descriptor, includes/excludes notes, and payer rules all constrain the choice.
What to do instead
Practice a repeatable four-step routine on every coding item: identify the key terms in the encounter description, read the complete descriptor rather than the short name, check the includes/excludes language, and confirm medical necessity in the documentation before the code is assigned. Remember that a modifier explains a circumstance; it does not create justification for a service that the record does not support.
Mixes up the claim form, the explanation of benefits, and the remittance advice, or reads the wrong line of the EOB when asked to identify the patient's financial responsibility.
The documents overlap in content and vocabulary, and candidates memorize them as a list of names rather than by direction of flow and purpose.
What to do instead
Anchor each document to sender and receiver. The claim travels from provider to payer. The explanation of benefits travels from payer to patient and explains what was paid, adjusted, and left as patient responsibility. The remittance advice travels from payer to provider with the payment. Then practice reading an EOB row by row, matching each column to allowed amount, paid amount, adjustment, and patient responsibility.
Describes open scheduling when the scenario clearly describes wave scheduling, or labels a grouped same-type appointment block as 'modified wave' when it is clustering.
The scheduling models sound interchangeable and candidates memorize the labels without attaching each one to its defining structural feature.
What to do instead
Learn each model by its distinctive pattern. Open hours: patients arrive any time within a window, first come first served. Wave: several patients are booked for the same start time and seen in sequence. Modified wave: patients are staggered at short intervals on top of a wave. Cluster: appointments of the same type are grouped together. Advanced: bookings are made well into the future. When reading a scenario, identify the pattern first and only then choose the label.
Matches a patient to a record using name alone - especially a common name - without a second identifier, and continues the transaction even when the date of birth or record number does not match.
Name matching feels intuitive and fast, and candidates underestimate how often the exam tests wrong-patient scenarios as a safety issue rather than a clerical one.
What to do instead
Commit to the two-identifier habit in every practice scenario: full name plus date of birth, or full name plus medical record number. If either identifier conflicts, stop, do not merge or overwrite anything, and escalate to the person responsible for record reconciliation. Treat every 'two patients with the same name' stem as a signal that the answer involves verification, not speed.
Files or retrieves records by first name, or reads a terminal-digit number from left to right, so that a chart is shelved in the wrong position within the practice's numbering system.
Candidates carry over everyday alphabetical habits and have not practiced reading numeric filing systems from the direction the system specifies.
What to do instead
Learn the three systems separately and state the rule aloud before answering. Straight numeric: read the whole number from left to right. Terminal digit: read the last two digits as the primary unit, the middle two as the secondary unit, and the first digits as the tertiary unit. Alphabetic: last name, then first name, then middle initial. Practice sorting a short list of ten numbers under each system until the direction becomes habitual.
Offers a clinical opinion or suggested treatment over the telephone when a patient describes symptoms, because it feels efficient and reassuring.
Candidates blur the administrative assistant's role with the provider's scope of practice and want to resolve the caller's problem rather than route it.
What to do instead
Memorize the escalation script: acknowledge the concern, document the reported symptoms in the patient's own words, and route to the provider or the practice's triage protocol. Never interpret symptoms, recommend medication, or confirm a diagnosis. When a caller pushes, restate the boundary and offer a concrete next step such as a same-day appointment or a provider callback time.
Interrupts a patient who speaks slowly or with limited English proficiency, finishes the patient's sentences, or accepts a family member as the interpreter because it seems faster.
Time pressure and discomfort with silence push candidates toward filling pauses, and relatives feel like a convenient solution in the moment.
What to do instead
Practice active listening deliberately: let the patient finish, use a brief facilitative phrase instead of a guess, and paraphrase back what was understood. For limited English proficiency, use a qualified medical interpreter, speak directly to the patient rather than to the interpreter, and confirm comprehension with teach-back. Keep the same standard for hearing impairment and cognitive differences.
Releases protected health information to a caller who claims to be a family member, or faxes a record to a number taken over the phone, without confirming authorization.
The minimum necessary and authorization rules get memorized as slogans rather than as a checklist, and the desire to be helpful overrides the verification step in the moment.
What to do instead
Apply the release-of-information sequence on every scenario: verify the requester's identity, confirm the legal authority (patient-signed authorization, personal representative documentation such as power of attorney or guardianship, or a permitted exception), check that the authorization contains all required elements including the specific recipient and expiration, disclose only the minimum necessary, and log the disclosure. When authority is unclear, the correct answer is to decline politely and explain how to obtain authorization.
Writes personal opinion, blame, or speculation in the patient record, back-dates an entry, or alters a previous note after the fact to make the schedule look better.
Candidates fear being blamed for a delay or an error and do not understand that the record is a legal document in which objectivity and audit trail matter more than appearance.
What to do instead
Write only objective, factual, time-stamped entries, and quote the patient when recording statements. If an entry is late, label it as a late entry with the actual date and time of writing. If an error must be corrected, draw a single line through the incorrect text, write 'error,' and add initials and date so the original remains legible. Never erase, overwrite, or destroy any part of the record.
