AAPC-CDEO Certified Documentation Expert Outpatient - Set 2 - Part 3

Correct Answer: Information is insufficient for a more specific code

Codes titled "unspecified" are used when the information in the medical record is insufficient to assign a more specific code. "Other" codes, by contrast, apply when the record gives detail but no specific code exists. Option b is incorrect because NEC in an Index line points to an "other" code in the Tabular List, representing a specific entity without its own code. Option c is incorrect because that describes an "other" or "other specified" code, which covers documented detail for which the classification has no specific code. Option d is incorrect because unrelated conditions bear on the "with" presumption and Excludes1 exceptions, not on the choice between specific and unspecified codes.

Correct Answer: Default code

A code listed next to a main term in the Alphabetic Index is a default code. It represents the condition most commonly associated with the main term, or the unspecified code, and is assigned when documentation adds no detail. Option a is incorrect because it is an instruction that two codes may be required to describe a condition, and it gives no sequencing direction. Option c is incorrect because NEC marks an Alphabetic Index line that points to an "other specified" code for a condition with no specific code. Option d is incorrect because inclusion terms are lists of conditions placed under a code in the Tabular List, not a code printed beside a main term in the Index.

Correct Answer: Code assignment depends on the clinical criteria the provider used to establish the diagnosis.

Code assignment rests on the provider's diagnostic statement that the condition exists. It is not based on the clinical criteria the provider used to establish the diagnosis, so the statement about depending on those criteria is the incorrect one. Option b is incorrect because a default code is listed next to the main term in the Alphabetic Index and is assigned when a condition appears with no added detail. Option c is incorrect because the guidelines assign the resolution of conflicting medical record documentation to the provider, so the coder queries instead of choosing between the entries. Option d is incorrect because this is the guideline itself: the provider's diagnostic statement that the condition exists is enough, so the coder needs nothing further to assign the code.

Correct Answer: Report the symptom code from the symptoms chapter

Official guidelines state that codes describing symptoms and signs, as opposed to diagnoses, are acceptable for reporting when a related definitive diagnosis has not been established (confirmed) by the provider. Option a is incorrect because the guidelines accept symptom and sign codes when a diagnosis is not established; they do not permit assigning an unconfirmed condition as if it were definitive. Option b is incorrect because codes for diagnoses, symptoms, conditions, problems or complaints must be used to identify the reason for the encounter, so reporting cannot be left empty. Option c is incorrect because a disease code implies a confirmed diagnosis, which the provider has not established, whereas the guidelines point to symptom and sign codes in this situation.

Correct Answer: Symptom code is not used as principal diagnosis

Codes for symptoms, signs, and ill-defined conditions from Chapter 18 are not to be used as principal diagnosis when a related definitive diagnosis has been established. The definitive diagnosis is selected instead. Option a is incorrect because the guidelines direct that Chapter 18 codes for symptoms and signs are not used as principal diagnosis once a related definitive diagnosis exists. Option b is incorrect because a single condition is selected as principal diagnosis, defined as the condition chiefly responsible for occasioning the admission after study. Option d is incorrect because free choice of sequencing applies to interrelated or equally qualifying conditions, not to a sign alongside its established definitive diagnosis.

Correct Answer: Additional clinically significant conditions that affect patient care

The guidelines interpret "other diagnoses" as additional clinically significant conditions that affect patient care by requiring clinical evaluation, therapeutic treatment, diagnostic procedures, extended length of stay, or increased nursing care and/or monitoring. Option a is incorrect because diagnoses relating to an earlier episode with no bearing on the current stay are excluded from reporting as other diagnoses. Option c is incorrect because the guidelines do not define other diagnoses by symptom status; they use clinical significance, such as requiring evaluation, treatment, or monitoring. Option d is incorrect because this wording is the UHDDS definition of principal diagnosis, which is the condition established after study, not the definition of other diagnoses.

Correct Answer: inpatient

The guidelines state that coding rules for inconclusive diagnoses (probable, suspected, rule out) were developed for inpatient reporting and do not apply to outpatients, so uncertain terms are handled differently by setting. Option a is incorrect because this setting is named alongside office visits as covered by the outpatient guidelines, which exclude the inconclusive-diagnosis rule rather than originate it. Option b is incorrect because same day surgery is an outpatient situation in which the reason for surgery is the first-listed diagnosis, not a setting that the uncertain-diagnosis rule was built for. Option d is incorrect because office visits fall under the outpatient guidelines, where uncertain terms are not coded as if established, so they are not the setting these rules were written for.

Correct Answer: Encounter for pre-procedural examinations

For patients receiving preoperative evaluations only, the outpatient guidelines sequence first the code from the encounter for pre-procedural examinations subcategory. The reason for surgery and any related findings are then reported as additional diagnoses. Option a is incorrect because this applies to routine general medical examinations where an abnormal finding results, which is a different encounter type from a preoperative evaluation only. Option b is incorrect because findings are coded in addition to the examination code, so they follow it rather than lead the claim. Option c is incorrect because the guidelines direct that this condition be assigned as an additional diagnosis after the pre-procedural examination code, not sequenced first.

Correct Answer: To assign the POA indicator to diagnoses already coded

The POA guidelines supplement the official guidelines by explaining how to apply the POA indicator to the final set of diagnosis and external cause of injury codes already assigned for institutional claims. Option b is incorrect because deciding whether a condition is coded falls to Sections I, II, and III of the official guidelines, and the POA guidelines apply only afterward. Option c is incorrect because the appendix works as a supplement and is expressly not intended to replace any guideline in the main body of the official guidelines. Option d is incorrect because the provider's clinical judgment about whether a condition was present on admission stays in place, and the POA guidelines do not stand in for it.

Correct Answer: Query the provider

The Excludes1 exception applies when two conditions are unrelated. If it is not clear whether the two conditions involving an Excludes1 note are related, the guidelines direct the coder to query the provider. Option a is incorrect because choosing one code is the rule for related conditions under an Excludes1 note, and here the relationship is unknown, so the guidelines call for clarification. Option b is incorrect because unspecified codes are tied to missing laterality or detail, and this situation calls for clarification rather than a default choice. Option c is incorrect because reporting both codes applies when the conditions are clearly unrelated, as with the teeth grinding and psychogenic dysmenorrhea example, not when the relationship is unclear.
