Filled maps to an HCC · hollow maps to none. Coefficients are Community, Non-Dual, Aged under CMS-HCC V28 PY2027; only the A form risk-adjusts.
— means CMS publishes no code for that behaviour. Different from 0.000, which means a code exists and risk-adjusts at zero.
The column is chosen by the documentation, not by the coder. Behaviour follows the pathology report (Guideline I.C.2). How these figures were derived.
Codes above link to their Tabular List entry. Guideline I.C.2 directs you to confirm every code there before assigning it — the table routes many sites onto shared codes, so the tabular title often names a broader category than the one you looked up.
