AAPC-CDEO Certified Documentation Expert Outpatient - Set 3 - Part 1

Correct Answer: Section IV

Section IV of the guidelines is for outpatient coding and reporting. Because all sections must be reviewed to understand the rules needed to code properly, Section IV is read together with the other three sections. Option a is incorrect because covers the structure and conventions of the classification, general guidelines and chapter-specific guidelines that apply across settings, not outpatient reporting specifically. Option c is incorrect because holds the guidelines for selecting a principal diagnosis in non-outpatient settings, so it does not address outpatient services. Option d is incorrect because deals with reporting additional diagnoses in non-outpatient settings, which places it outside outpatient coding.

Correct Answer: The X must be used where a placeholder exists

ICD-10-CM uses the placeholder character X at certain codes to allow for future expansion. Where a placeholder exists, the X must be entered for the code to be considered valid, so leaving the position empty makes the code invalid. Option b is incorrect because the guidelines state the reverse: for reporting purposes only codes are permissible, and categories or subcategories are not, so this would make the claim worse. Option c is incorrect because an applicable 7th character is required, and a code that has one is considered invalid without it, so it cannot be treated as optional. Option d is incorrect because precedence runs the other way, since the conventions and instructions of the classification outrank the guidelines, and this does not address the empty position.

Correct Answer: As either "and" or "or"

The ICD-10-CM guideline on "And" says the word is interpreted as either "and" or "or" in a title. Tuberculosis of bones, of joints, or of both therefore classifies to the same subcategory. Option a is incorrect because the guidelines do not restrict the word to a joint meaning; the example of tuberculosis of bones, joints, or both shows single conditions fit the title. Option b is incorrect because that phrase is the meaning of an Excludes1 note, which marks codes that are independent of each other, and it has no link to "and". Option d is incorrect because that interpretation belongs to the words "with" and "in", which presume a causal relationship between linked conditions, not to "and" in a title.

Correct Answer: "Associated with" or "due to"

The guidelines state that "with" or "in" means "associated with" or "due to." The classification therefore presumes a causal relationship between the linked conditions, even without explicit provider documentation of the link. Option a is incorrect because that phrase describes codes for details lacking a specific code, a different convention that has nothing to do with linking two conditions. Option b is incorrect because that is the interpretation given to the word "and" in a title, not to "with" or "in". Option c is incorrect because that wording defines an Excludes1 note, which marks codes as independent of each other rather than presuming a relationship between conditions.

Correct Answer: The highest level of specificity

The outpatient guidelines direct the coder to code to the highest level of specificity when supported by the medical record documentation. Documentation determines how detailed the assigned code can be. Option b is incorrect because a default code is the condition most commonly associated with a main term or the unspecified code, used when no further detail is documented. Option c is incorrect because this phrase governs uncertain diagnoses, directing the coder to report symptoms or signs instead of terms like probable or suspected, not the detail level of a code. Option d is incorrect because the Alphabetic Index does not always provide the full code, so stopping there can miss laterality or a 7th character found only in the Tabular List.

Correct Answer: Code both, sequencing the acute code first

When the same condition is described as both acute (subacute) and chronic, and separate subentries exist in the Alphabetic Index at the same indentation level, both are coded and the acute (subacute) code is sequenced first. Option a is incorrect because the guideline places the acute (subacute) code ahead of the chronic code, so reversing the order contradicts the sequencing instruction. Option b is incorrect because when both subentries exist at the same indentation level, the guideline directs that both be coded, not that one be dropped. Option c is incorrect because a combination code classifies two diagnoses or a diagnosis with a manifestation or complication, which is a different situation from one condition described as acute and chronic.

Correct Answer: Documentation clearly states the conditions are unrelated

The "with" convention presumes a causal relationship between linked conditions, so they are coded as related unless the documentation clearly states they are unrelated, or another guideline requires documented linkage. Option a is incorrect because a "code also" note only says two codes may be needed to describe a condition and gives no sequencing direction or unrelatedness rule. Option b is incorrect because bracketed codes mark the etiology/manifestation convention, where the bracketed code is sequenced second; this does not make the conditions unrelated. Option d is incorrect because the classification presumes a causal relationship and codes the conditions as related even when the provider has not explicitly linked them in the documentation.

Correct Answer: The condition for which the rehabilitation is being performed

When the purpose of the admission is rehabilitation, the guidelines direct that the condition for which the service is being performed is sequenced first. Aftercare applies only if that condition is no longer present. Option b is incorrect because conditions from previous admissions with no bearing on the current stay are not reported, so they cannot be sequenced first. Option c is incorrect because symptom and sign codes are not used as principal diagnosis when a related definitive diagnosis has been established, as it has here. Option d is incorrect because aftercare is reported first only when the condition being treated by rehabilitation is no longer present, and here the deficit remains.

Correct Answer: Section I conventions, general and chapter-specific guidelines

Section IV states that the Section I conventions, general coding guidelines and chapter-specific guidelines should also be applied for outpatient services and office visits, because they apply to all health care settings unless otherwise indicated. Option a is incorrect because the guidance states these were developed for inpatient reporting and do not apply to outpatients, so uncertain terms are handled differently there. Option c is incorrect because these guidelines rest on the UHDDS definitions of other diagnoses, which apply to inpatient and other non-outpatient settings, not to outpatient encounters. Option d is incorrect because principal diagnosis selection belongs to inpatient reporting, and the UHDDS definition of principal diagnosis does not apply to hospital-based outpatient services or provider-based office visits.

Correct Answer: medical condition

Under the outpatient guidelines for an observation stay, when a patient is admitted for observation for a medical condition, a code for that medical condition is assigned as the first-listed diagnosis. Option a is incorrect because a postoperative diagnosis applies to ambulatory surgery when it differs from the preoperative one, which is a separate rule from observation for a medical condition. Option b is incorrect because the guideline names the condition that prompted the admission as first-listed, not the service of observation, which is not itself the reason for the encounter. Option c is incorrect because outpatient guidance directs assignment of a code for the medical condition itself, and signs and symptoms are reported only when no diagnosis has been established by the provider.

Correct Answer: First-listed, using the code with abnormal findings

Under Section IV.P, a general medical examination that produces an abnormal finding, such as a newly identified condition, takes the examination code with abnormal finding as the first-listed diagnosis, followed by a secondary code for the finding. Option a is incorrect because the guidelines direct that the examination code with abnormal finding be first-listed, while the finding itself becomes the secondary code. Option b is incorrect because an abnormal finding does not remove the examination code; the guidelines still assign it and add a secondary code for the finding. Option d is incorrect because the without-abnormal-findings subcategory applies when the examination finds nothing new, but here a newly identified condition makes the abnormal-findings code the correct choice.

Correct Answer: Leave the indicator unreported

Codes and categories on the CDC exempt list describe circumstances of the encounter or factors influencing health status that are not a current disease or injury, or are always present on admission. Such codes are unreported or not used for POA. Option a is incorrect because W is used when the provider cannot clinically determine whether a condition was present on admission, which does not describe an exempt code. Option b is incorrect because U signals that documentation is insufficient to determine presence on admission, which is a documentation problem and not a feature of exempt codes. Option c is incorrect because Y means the condition was present at the time of inpatient admission, and it is reserved for reportable codes, not exempt ones.

Correct Answer: Ordering medically unnecessary diagnostic testing to reach a more specific code

The guidelines call it inappropriate to conduct medically unnecessary diagnostic testing in order to determine a more specific code. Unclear documentation is handled by querying the provider or by reporting sign/symptom or unspecified codes. Option a is incorrect because the guidelines call unspecified codes acceptable when not enough is known about a condition, for example pneumonia determined without its specific type. Option c is incorrect because the guidelines direct the coder to ask the provider for clarification when documentation does not make the relationship between the condition and the care or procedure clear. Option d is incorrect because coders are encouraged to query whenever documentation regarding a borderline condition is unclear, so this action is supported rather than excluded.

Correct Answer: The identity of the care giver

OIG guidance states that a properly documented medical record may validate the site of the service, the appropriateness of the services, the accuracy of the billing, and the identity of the care giver (service provider). Option a is incorrect because a fee schedule belongs to payer reimbursement rules; the record is described as validating the service and billing accuracy, not the schedule used. Option b is incorrect because denial rate is a quality-improvement comparison the practice makes against other practices in its specialty, not something the medical record itself validates. Option c is incorrect because eligibility is not among the items OIG guidance lists for validation by the record; the list names site, appropriateness, billing accuracy and care giver identity.

Correct Answer: I and III

Documentation serves patient care and verifies bill accuracy (I). Sufficient documentation is a condition of a valid claim, since records must verify the services performed and the level of care billed (III). Statements II and IV contradict Medicare guidance. Option b is incorrect because statement II is contradicted by Medicare guidance: when the record supports a higher or lower level code, contractors adjust the code and the payment instead of denying the claim. Option c is incorrect because it pairs two inaccurate statements, since level discrepancies lead to code adjustment and insufficiently documented paid claims may be considered overpayments. Option d is incorrect because statement III is sound, but IV fails because payment on claims already paid may be considered an overpayment and be recovered partially or fully.

Correct Answer: Considered not done

Any entry in the EHR is a legal document, and in court it is generally viewed that "If it wasn't documented, it wasn't done." A service with no record entry is therefore regarded as not performed. Option a is incorrect because the guidance requires documentation to be completed accurately and timely after the task, so after-the-fact statements do not replace a missing entry. Option b is incorrect because payment is not the test; the legal view ties the service to what was documented in the record, not to claim outcome. Option d is incorrect because an order supports appropriateness of a service but does not itself show the service occurred; the record must verify what was actually provided.

Correct Answer: Assessment, clinical impression, or diagnosis

OIG guidance says documentation of each patient encounter includes the reason for the encounter, history, examination findings, prior diagnostic test results, assessment, clinical impression, or diagnosis, plan of care, and date and legible identity of the observer. The assessment is the missing piece. Option b is incorrect because a plan of care appears in the note as described, which means the auditor has found that element and nothing is missing there. Option c is incorrect because the scenario states the note already records why the patient came in, so this element is present and cannot be the gap. Option d is incorrect because examination findings are recorded in the note according to the scenario, so the missing item lies elsewhere in the list of required encounter elements.

Correct Answer: Patient's progress, response to treatment and diagnosis revision

OIG guidance lists, as an internal documentation guideline, that the patient's progress, response to and any changes in treatment, and any revision in diagnosis is documented. The entry described matches this element. Option a is incorrect because this element identifies who made the entry and when, which supports the identity of the care giver, not the clinical course of the patient. Option b is incorrect because this element records why the patient presented for the visit, so it describes the start of the encounter rather than later improvement or a changed diagnosis. Option d is incorrect because the guidance treats this as a separate element, explaining why diagnostic or other ancillary services were ordered, and the entry described does not address any order.

Correct Answer: Treatment Administration Record

In many facilities, treatments such as wound care are documented on a Treatment Administration Record. A dressing change is a treatment, so the nurse charts it there, apart from medication records, orders and test results. Option a is incorrect because this section holds results from blood work and other lab tests, so a dressing change entry has no place there. Option c is incorrect because this section lists the prescriptions or medical orders a nurse must implement or communicate; it is not where the completed treatment itself gets documented. Option d is incorrect because this record is where nurses chart medications given, and it links provider medication orders with pharmacists, so it does not hold wound care treatments.

Correct Answer: Narrative note

A narrative note, also called a summary note, is a type of progress note that chronicles assessment findings and nursing activities for the client throughout the entire shift or visit. Option a is incorrect because it organizes entries under set headings (Subjective, Objective, Assessment, Plan, Intervention, Evaluation) and does not give a free summary of the entire shift or visit. Option b is incorrect because it records the client's departure, such as time, transportation, condition, education and follow-up, and is not a running account of the whole visit. Option d is incorrect because this safety tool is completed for an unexpected occurrence such as a fall or near miss, and it stays outside the medical record.
