What do HCC coders focus on?

What do HCC coders focus on?

• A. Diagnoses that are never risk-adjusting
• B. Diagnoses that are risk-adjusting, chronic or acute based on severity and cost
• C. Diagnoses only for rare diseases
• D. Diagnoses that must be documented in every quarterly report

Answer: (B)

The main concept here is how HCC coding ties diagnoses to risk adjustment. In this system, each diagnosed condition can map to an HCC that adds to a patient’s risk score, so coders focus on diagnoses that actually drive cost and resource use. These are typically chronic conditions or acute conditions that are severe enough to influence future care and expenses. The coder’s job is to verify that documentation supports these conditions and assign the correct ICD-10-CM codes that map to HCCs. Severity matters—conditions with greater severity or ongoing management often have a larger or different HCC and thus a bigger impact on the risk score. The model also uses a hierarchy so related diagnoses aren’t double-counted; only the most impactful code in a category is counted toward the risk adjustment. So, diagnoses that don’t affect risk scores or lack proper documentation aren’t the focus. It’s the risk-adjusting diagnoses—often chronic diseases or severe acute conditions—that HCC coders target.
