RAF attribution: where the lift actually comes from.

The four buckets behind a +0.14 lift.

Most CFOs see a single RAF lift number on a quarterly scorecard and cannot trace it. The number is real. The question is what produced it, and which of the underlying mechanisms is still under-exploited. On an engaged Medicare Advantage book, the typical +0.14 RAF lift decomposes into four distinct buckets, each with its own queue, its own training, and its own ceiling.

Suspect-driven coding contributes about +0.041. This is the work of a pre-encounter queue that surfaces likely HCCs from prior claims, labs, medications, and last year's documented conditions, then routes them to the provider as in-encounter prompts. Recapture of chronic conditions contributes about +0.058 and is consistently the largest line item, because chronic conditions like CKD, diabetes with manifestations, and heart failure do not get re-coded by default every calendar year. Gap closure on documented but never billed conditions adds about +0.024. Net new diagnoses surfaced during pre-encounter prep or the Annual Wellness Visit add the remaining +0.017.

The reason recapture wins is mechanical. Suspect lists and gap dashboards both rely on someone surfacing the right items at the right time. The AWV is the only encounter type that forces a structured chronic-condition review on every patient, every year. It surfaces recapture without requiring a separate operational layer.

V28 recalibration: who moved, who didn't.

V28 is phased in across three payment years on a one-third, two-thirds, full schedule. Payment year 2026 is the first year of full V28 weighting. Practices that rebuilt PMPM models against the 2025 blend are still under-modeling their downside if their panel skews toward the categories CMS cut hardest.

The top movers, by weight delta from V24 to V28 at full phase-in: CKD stage 3 dropped roughly 33 percent. Vascular disease without complications dropped roughly 49 percent. Major depression dropped roughly 24 percent. Diabetes without complications dropped roughly 26 percent. Diabetes with manifestations held flat, which makes specificity the difference between holding revenue and losing it. Heart failure categories shifted modestly upward, around 8 percent net.

Practice impact is non-uniform. A primary care group heavy in long-standing diabetics and stage 3 CKD will see a steeper RAF compression than a multi-specialty group with a strong cardiology presence. The cure is documentation specificity at the chart level, paired with a V28 crosswalk audit of the most-used ICD-10 codes against their new category mapping. The audit is two days of work and surfaces six-figure annual revenue movement on a typical engaged book.

AWV completion is the operational lift.

The Annual Wellness Visit is the highest-leverage operational change a Medicare Advantage practice can make. In our engaged book, practices completing AWVs on 88 percent or more of their MA panel show a +0.18 RAF lift on average. Practices below 50 percent completion sit at +0.08. The gap, roughly +0.10 RAF, is worth about $400 to $500 per member per year on a typical CMS benchmark.

The mechanism is structural. The AWV is the only encounter that forces a full chronic-condition review, a Health Risk Assessment, a cognitive screen, a fall-risk assessment, and a care-plan refresh in one billable visit. It surfaces recapture and gap closures in the same hour. Schedulers calling MA patients for an AWV first, then layering on the problem-focused visit if needed, hit completion targets far faster than practices that wait for the patient to ask.
