Clinical Scenario 1 — ICD-10-CM Coding

ICD-10-CM

Clinical Note (Redacted):
Patient is a 67-year-old Medicare Advantage enrollee presenting with Type 2 diabetes mellitus with diabetic chronic kidney disease, Stage 3. Patient also has documented hypertension and is on insulin therapy. No acute conditions noted today. Routine management visit.

Assign the most accurate ICD-10-CM code set for this encounter. Select ALL applicable codes:

a) E11.65 — Type 2 diabetes mellitus with hyperglycemia b) E11.22 — Type 2 DM with diabetic CKD c) N18.3 — Chronic kidney disease, stage 3 d) I10 — Essential (primary) hypertension e) Z79.4 — Long-term (current) use of insulin f) E11.9 — Type 2 DM without complications

Clinical Scenario 2 — CPT Modifier Usage

CPT Modifiers

Scenario:
A patient presents for an annual wellness visit (AWV). During the same encounter, the physician identifies a new, acute problem — uncontrolled hypertension — and performs a significant, separately identifiable evaluation and management service beyond the scope of the AWV.

Which modifier should be appended to the E&M service code to indicate it is a distinct and separately identifiable service?

a) Modifier 24 — Unrelated E&M during postoperative period b) Modifier 25 — Significant, separately identifiable E&M service on same day c) Modifier 51 — Multiple procedures d) Modifier 59 — Distinct procedural service e) Modifier 33 — Preventive services

Clinical Scenario 3 — HCC Risk Adjustment

HCC / RAF

Clinical Note:
Medicare Advantage beneficiary. Chart review for prospective HCC risk adjustment. Documented conditions this encounter include: Congestive heart failure (CHF), systolic, chronic and atrial fibrillation. Previous year's chart listed HF but type not specified. Coding accuracy for RAF score is critical.

Which ICD-10-CM code best captures the specificity needed for accurate HCC RAF score optimisation?

a) I50.9 — Heart failure, unspecified b) I50.22 — Chronic systolic (congestive) heart failure c) I50.20 — Unspecified systolic (congestive) heart failure d) I50.30 — Unspecified diastolic (congestive) heart failure

Clinical Scenario 4 — NCCI Edit / Bundling

NCCI / Bundling

Denial Scenario:
A claim for an outpatient surgical procedure was denied. The denial EOB reads: "Services denied — NCCI bundling edit applied. Column 2 code is a component of the Column 1 procedure and cannot be billed separately without a valid modifier exception."

Which modifier, if clinically supported and documented, would provide the most appropriate exception to override this NCCI bundle edit?

a) Modifier 25 — Significant separately identifiable E&M b) Modifier 52 — Reduced services c) Modifier 59 — Distinct procedural service (or XS/XT/XE/XU) d) Modifier 76 — Repeat procedure by same physician

Clinical Scenario 5 — Coding Guidelines

ICD-10-CM Guidelines

Scenario:
During a hospital inpatient stay, the attending physician documents "probable pneumonia" as the principal diagnosis in the discharge summary. The patient was treated accordingly throughout the stay.

Per ICD-10-CM Official Guidelines, how should "probable pneumonia" be coded for this inpatient encounter?

a) Code the symptoms and signs that prompted the admission, not the probable diagnosis b) Code the condition as if it were established (probable pneumonia = code pneumonia) c) Code as "unspecified respiratory condition" since diagnosis is uncertain d) Do not code — document a query to the physician first
