AAPC-CIC Certified Inpatient Coder - Set 2 - Part 2

Correct Answer: Do not code it unless the provider indicates clinical significance

Section III.B states abnormal findings (laboratory, x-ray, pathologic, and other diagnostic results) are not coded and reported unless the provider indicates their clinical significance. Without that indication, the coder does not report the result. Option a is incorrect because an out-of-range value alone does not make a finding reportable; the guidelines require the provider to indicate its clinical significance first. Option c is incorrect because first-listed diagnosis is an outpatient term used in lieu of principal diagnosis, and it does not make an unaddressed abnormal finding reportable. Option d is incorrect because the uncertain diagnosis guideline covers conditions documented at discharge with terms like probable or suspected, not unaddressed laboratory values.

Correct Answer: A presumed causal relationship between the conditions

The guidelines interpret "with" or "in" as "associated with" or "due to", so the classification presumes a causal relationship between the linked conditions and they are coded as related without explicit provider documentation. Option a is incorrect because provider documentation must link conditions only when the classification does not join them by these terms or when a guideline requires documented linkage. Option b is incorrect because the guidelines read "with" as "associated with" or "due to", so the conditions are coded as related unless documentation clearly states they are unrelated. Option d is incorrect because alphabetical order is a separate point: "with" is sequenced right after the main term or subterm, which describes position and not how the link is interpreted.

Correct Answer: Once for the encounter

Each unique ICD-10-CM diagnosis code may be reported only once for an encounter. This includes two different conditions classified to the same code, and bilateral conditions without distinct laterality codes. Option b is incorrect because the guideline applies to two different conditions classified to the same code, so a separate report for each condition is not permitted. Option c is incorrect because reporting is tied to the encounter, not to the number of days; daily repetition of a unique code is not part of the guideline. Option d is incorrect because a query is used for conflicting documentation and does not create an exception to the limit of one report per unique code.

Correct Answer: Tabular List

The guidelines state that the Alphabetic Index does not always provide the full code. Selection of the full code, including laterality and any applicable 7th character, can only be done in the Tabular List. Option a is incorrect because the record supplies the provider's diagnostic statement and level of specificity, yet the classification's Tabular List is what supplies the characters of the code. Option b is incorrect because the Alphabetic Index does not always provide the full code, so it is the starting point for locating a term, not where selection is finalized. Option d is incorrect because conventions are instructional notations read in both the Index and Tabular List; they guide the coder but are not the place where the full code is selected.

Correct Answer: Not assigned as an additional code

Signs and symptoms that are associated routinely with a disease process are integral to it and should not be assigned as additional codes, unless the classification instructs otherwise. Option a is incorrect because this is the handling for signs and symptoms not associated routinely with the disease process, which the guidelines say should be coded when present. Option c is incorrect because symptom codes stand in for a diagnosis only when no related definitive diagnosis has been established, and here the disease is already coded. Option d is incorrect because the guidelines give no query step for routine findings; they simply direct that such signs and symptoms are left uncoded unless the classification instructs otherwise.

Correct Answer: 7th

ICD-10-CM guidelines state that a code is invalid if it lacks the full number of characters required, including the 7th character, if applicable. Codes are reported at their highest number of characters available. Option b is incorrect because the fifth character is another optional subdividing position that applies only to some categories, whereas the validity rule names the final position that is required only where applicable. Option c is incorrect because the fourth character is one of the subdividing characters that adds detail to a category, but the validity rule singles out a later position. Option d is incorrect because the first three characters form the category heading, and a code stopping there is acceptable when the category is not further subdivided, so it is not the one named.

Correct Answer: Query the provider for clarification

Code assignment for complications of care rests on the provider's documentation of the relationship between the condition and the care or procedure. When that relationship is not clear, the guidelines direct the coder to query the provider. Option a is incorrect because the guidelines state that not all conditions occurring during or following care are complications, so a complication code is not assumed without a documented cause-and-effect relationship. Option b is incorrect because a borderline diagnosis is a documented term coded as confirmed, and it has nothing to do with clarifying a link to care. Option d is incorrect because sign/symptom codes are for encounters where a definitive diagnosis has not been established, which does not resolve an unclear link between a condition and care.

Correct Answer: Combination code

A combination code is a single code used to classify two diagnoses, a diagnosis with an associated secondary process (manifestation), or a diagnosis with an associated complication, according to the ICD-10-CM guidelines. Option a is incorrect because guidelines call for a secondary code only when a combination code lacks necessary specificity, so it is an addition and not the single classifying code. Option b is incorrect because an acute code is sequenced first when the same condition is described as both acute and chronic, which involves two codes. Option c is incorrect because a sequela code classifies the residual effect left after the acute phase of an illness or injury has ended, not two diagnoses together.

Correct Answer: The provider's documentation of the relationship between condition and care

Complication code assignment rests on the provider's documentation of the relationship between the condition and the care or procedure, unless the classification instructs otherwise. A cause-and-effect relationship must be documented, and not every postoperative condition qualifies. Option a is incorrect because acute and chronic sequencing governs the order of codes for the same condition, and has no bearing on linking a condition to care. Option c is incorrect because the guideline places the decision on provider documentation, not on the coder's own reading of when the condition occurred relative to care. Option d is incorrect because a combination code classifies two diagnoses or a diagnosis with its manifestation or complication; it does not establish whether care caused the condition.

Correct Answer: A secondary code should be added, if known

A “use additional code” note appears at codes outside etiology/manifestation pairs where a secondary code helps fully describe a condition. The note tells the coder to add that secondary code, if known, following the same sequencing rule as the pair. Option a is incorrect because single-code reporting applies when a combination code fully identifies every documented element, whereas this note calls for adding a second code to describe the condition. Option b is incorrect because this describes a “code, if applicable, any causal condition first” note, which lets the code be principal only when no causal condition is known or applicable. Option c is incorrect because that instruction belongs to a “code first” note, which places the underlying cause ahead of the code carrying the note.

Correct Answer: The appropriate aftercare code

When the purpose of admission is rehabilitation and the condition no longer exists, the appropriate aftercare code is the first-listed or principal diagnosis, unless the service follows an injury. The joint replacement example illustrates this. Option b is incorrect because rehabilitation guidance directs sequencing of a diagnosis code for the condition or its aftercare; a procedure is not the first-listed or principal diagnosis. Option c is incorrect because symptom, sign and ill-defined condition codes are not used as principal diagnosis when a related definitive diagnosis has been established, as here. Option d is incorrect because that code is reserved for rehabilitation following active treatment of an injury, and the stem states that no injury is involved.

Correct Answer: A Chapter 18 symptom code serves as principal diagnosis when a related definitive diagnosis is established.

Section II says Chapter 18 codes for symptoms, signs, and ill-defined conditions are not to be used as principal diagnosis when a related definitive diagnosis has been established. The option states the opposite of that guideline. Option a is incorrect because Section II states this order of authority itself, so the option agrees with the guidelines and cannot be the statement that conflicts with them. Option b is incorrect because it restates the original treatment plan not carried out guideline, so it is a true statement and not the exception the question asks for. Option d is incorrect because Section II directs exactly this for complications of surgery and other medical care, which makes it a consistent statement rather than the odd one out.

Correct Answer: Code both as confirmed; either may be sequenced first

Section II.D states that contrasting or comparative diagnoses documented as "either/or" are coded as if confirmed and sequenced by the circumstances of admission. If no further determination is possible, either diagnosis may be sequenced first. Option a is incorrect because the guideline directs that both contrasting diagnoses be coded as if confirmed, not that one be dropped based on its order in the record. Option b is incorrect because symptom codes are not used as principal diagnosis when a related definitive diagnosis exists, and the guideline treats both diagnoses as confirmed anyway. Option c is incorrect because the guideline already supplies the rule for this situation, allowing either diagnosis to be sequenced first and requiring no further determination.

Correct Answer: Any one of the diagnoses may be sequenced first

Section II.C of the Official Guidelines states that when two or more diagnoses equally meet the criteria for principal diagnosis and no other guideline or convention gives sequencing direction, any one of them may be sequenced first. Option a is incorrect because contrasting or comparative diagnoses documented as either/or are coded as if confirmed, so none is excluded from sequencing under the guidelines. Option c is incorrect because the guidelines base sequencing on the circumstances of admission, diagnostic workup and therapy provided, and set no rule favoring the condition treated last. Option d is incorrect because symptom, sign and ill-defined condition codes from Chapter 18 are not used as principal diagnosis when a related definitive diagnosis is established, so they gain no priority.

Correct Answer: Do not report it unless hospital policy requires

Section III.A states that resolved conditions from previous admissions with no bearing on the current stay are not reported. They are coded only if hospital policy requires it, consistent with the UHDDS exclusion of earlier-episode diagnoses. Option b is incorrect because a query applies to abnormal findings that the provider has not addressed, not to a diagnosis already listed that is unrelated to the current stay. Option c is incorrect because uncertain diagnosis guidance covers conditions qualified with terms like probable or suspected at discharge, which does not describe a resolved earlier condition. Option d is incorrect because principal diagnosis is the condition chiefly responsible for the admission, and a resolved condition with no bearing on the stay does not meet that definition.

Correct Answer: First-listed diagnosis

The outpatient guidelines state that the term first-listed diagnosis is used in lieu of principal diagnosis, because the UHDDS definition of principal diagnosis does not apply to hospital-based outpatient services and provider-based office visits. Option a is incorrect because the outpatient guidelines do not name it as the substitute for principal diagnosis; the term they give for that purpose is first-listed diagnosis. Option b is incorrect because it is a UHDDS inpatient term for conditions that coexist, develop later, or affect treatment or length of stay, not the outpatient counterpart. Option d is incorrect because outpatient encounters and visits are not admissions, and the guidelines do not use this phrase to replace principal diagnosis in that setting.

Correct Answer: Code

Under the Format and Structure convention, the final level of subdivision is a code. Codes that have applicable 7th characters are still referred to as codes, not subcategories, and are invalid without the 7th character. Option b is incorrect because the placeholder is the character X, used to fill empty positions so a code is valid; it is a character, not a classification level. Option c is incorrect because the guidelines expressly state that entries with applicable 7th characters are still referred to as codes, not subcategories, which are only 4 or 5 characters. Option d is incorrect because every category is exactly 3 characters, so an entry carrying a 7th character cannot sit at that first level of the hierarchy.

Correct Answer: FL 66

FL 66 is the Diagnosis and Procedure Code Qualifier, also called the ICD Version Indicator. It is a required field that denotes the version of the International Classification of Diseases reported on the claim. Option a is incorrect because it holds the principal diagnosis code with its POA indicator, so it reports the diagnosis itself and not the ICD edition. Option b is incorrect because it is the first of the other diagnosis fields, each pairing an additional diagnosis with a POA indicator rather than a version qualifier. Option c is incorrect because it carries the admitting diagnosis code, which describes the condition at admission and does not denote the ICD version.

Correct Answer: admitting diagnosis

For inpatient hospital claims subject to QIO review, the admitting diagnosis is required in FL 69. It is defined as the condition identified by the physician at the time of admission requiring hospitalization. Option a is incorrect because such codes cover conditions that coexist or develop subsequently during treatment, so they do not describe the condition identified at admission. Option b is incorrect because it is a situational element tied to outpatient bill types and specific admission priority codes, not to inpatient QIO review claims. Option d is incorrect because it is the condition established after study to be chiefly responsible for the admission, entered in FL 67 rather than FL 69.

Correct Answer: When the order for inpatient admission occurs

Present on admission means present at the time the order for inpatient admission occurs. Conditions arising during outpatient encounters such as emergency department, observation, or outpatient surgery are therefore considered present on admission. Option a is incorrect because conditions that develop during an outpatient encounter, including emergency department care, are still counted as present on admission, so arrival is not the defining moment. Option c is incorrect because code assignment follows the coding guidelines and comes first; the POA indicator is then applied to conditions already coded, so it does not set the timing. Option d is incorrect because the guidelines set no required timeframe for documentation, and a diagnosis made days after admission does not mean the condition was absent at admission.
