QUESTION 1.
A risk adjustment coder reviews a Medicare Advantage patient record
containing documentation of diabetes mellitus with chronic kidney disease. The
provider documents diabetes and CKD but does not specify the relationship
,between the two conditions. Based on ICD-10-CM coding guidelines, what is
the most appropriate coding approach?
A. Assign a diabetes-with-CKD combination code because all CKD in a
diabetic patient is automatically linked.
B. Assign only the CKD code because diabetes cannot be coded without
explicit linkage.
C. Assign separate diabetes and CKD codes because the relationship must
always be separately documented.
D. Assign a diabetes-with-CKD combination code because ICD-10-CM
presumes a causal relationship between diabetes and CKD unless
documentation states otherwise.
🔴 Correct Answer: D. Assign a diabetes-with-CKD combination code
because ICD-10-CM presumes a causal relationship between diabetes and
CKD unless documentation states otherwise.
🔵 Explanation: ICD-10-CM assumes a causal relationship between diabetes
and certain associated conditions, including chronic kidney disease, unless the
provider clearly documents that the conditions are unrelated. The coder must
assign the appropriate diabetes combination code and an additional code to
identify the stage of CKD. Option A is incomplete because it does not mention
the additional CKD stage code requirement. Options B and C incorrectly apply
stricter documentation rules than ICD-10-CM requires.
QUESTION 2.
A risk adjustment auditor identifies that a provider documented "history of
congestive heart failure" during an annual wellness visit. The condition is not
assessed, treated, monitored, or linked to current clinical management. How
should the coder handle this documentation for risk adjustment purposes?
A. Code congestive heart failure because any mention of the condition impacts
risk scoring.
B. Do not code congestive heart failure because historical conditions without
current evaluation generally do not support active risk adjustment coding.
C. Assign the highest severity heart failure code based on the patient's previous
diagnosis.
, D. Query the provider requesting confirmation that the patient still has heart
failure.
🔴 Correct Answer: B. Do not code congestive heart failure because
historical conditions without current evaluation generally do not support
active risk adjustment coding.
🔵 Explanation: Risk adjustment coding requires that conditions reported for
the current encounter be supported by documentation showing evaluation,
assessment, monitoring, or treatment. A historical mention alone does not
establish a reportable active condition. Option A incorrectly assumes every
mention qualifies. Option C assigns unsupported severity, and Option D is
unnecessary unless there is conflicting or incomplete current documentation
requiring clarification.
QUESTION 3.
A coder reviews a complex patient encounter where the provider documents
hypertension, diabetes, and chronic kidney disease stage 4. The record contains
no statement regarding whether the CKD is related to diabetes. Which coding
principle should guide the coder's decision?
A. Assign diabetes with CKD because ICD-10-CM presumes the relationship
between diabetes and CKD.
B. Assign only hypertension and CKD because diabetes cannot be linked
without explicit wording.
C. Assign diabetes, CKD stage 4, and hypertensive chronic kidney disease
codes when documentation supports hypertension and CKD coexistence.
D. Assign CKD only because risk adjustment rules prohibit combination
coding.
🔴 Correct Answer: C. Assign diabetes, CKD stage 4, and hypertensive
chronic kidney disease codes when documentation supports hypertension
and CKD coexistence.
🔵 Explanation: ICD-10-CM presumes relationships between hypertension and
CKD as well as diabetes and CKD unless documentation states otherwise. Both
combination code categories may apply when the clinical documentation
supports the conditions. The CKD stage must also be coded separately. Options
, B and D incorrectly ignore established coding conventions, while Option A fails
to capture the hypertensive CKD relationship.
QUESTION 4.
During a risk adjustment review, a provider documents "COPD exacerbation"
and "acute respiratory failure" in the assessment. The coder verifies that the
clinical indicators support both conditions. Which action best represents
accurate risk adjustment coding practice?
A. Code only COPD because acute respiratory failure is a symptom of COPD.
B. Code both conditions because both diagnoses were documented, evaluated,
and clinically supported.
C. Code acute respiratory failure only because it represents the higher severity
condition.
D. Exclude acute respiratory failure because it requires inpatient documentation
only.
🔴 Correct Answer: B. Code both conditions because both diagnoses were
documented, evaluated, and clinically supported.
🔵 Explanation: When multiple conditions are documented, evaluated, and
clinically supported, each reportable condition should be coded according to
ICD-10-CM guidelines. Acute respiratory failure may represent a significant
severity condition separate from COPD exacerbation. Option A incorrectly
treats a major diagnosis as merely a symptom. Options C and D improperly
eliminate a supported diagnosis.
QUESTION 5.
A physician documents "diabetic neuropathy" in the assessment section but
does not specify the type of neuropathy. Which coding approach is most
appropriate?
A. Assign an unspecified diabetic neuropathy code when the documentation
supports the condition but lacks further specificity.
B. Assign diabetic peripheral angiopathy because neuropathy and vascular
disease are equivalent.
C. Assign diabetes without complication because the neuropathy type is
unclear.
