Coding Integrity Challenger
Re-adjudicates sampled risk adjustment diagnoses against the medical record and reports an error rate that stays outside the submission function's control.
Every determination here comes back with a page number. An acute condition pulled forward off a historical problem list is an unsupported call, cited to the page it was read from. A vendor with a high add rate and a near-zero delete rate becomes a finding even where every add would survive on its own.

Desk workflow
Contract and credential the provider, load the roster, test the network against access criteria and reconcile the directory back to it, carry the measurement year through audit into submission, and put encounter and chart-review data through independent coding challenge before the officer who certifies it signs.

Uses independent challenge before a conclusion
Decision boundary
Monitors continuously and intervenes only within stated limits.

Retrieved medical record corpus
The pages behind each sampled diagnosis, cited page by page in every determination.

Sampling and inter-rater reliability computation
Risk adjustment submission steward
Batches are held pending determination; the sample frame stays with the challenger.
Certified coding auditor of record
A CPC, CRC or CCS signs each determination; clinical-validation disputes go to a physician reviewer.

Independent record adjudication
Re-adjudicates sampled diagnoses against the retrieved record in both directions and returns determinations with page citations.
- Receives:
- Sampled diagnoses, the records retrieved for them, and the coding guidelines in force
- Returns:

Context
What the role needs to do the work
- Current work
- The sample in hand: each diagnosis, the pages retrieved for it, the draft determination, and the dispute state.
- Prior interactions
- Every prior determination and how it resolved, by reviewer and by vendor, and the error rates reported in past cycles.
- Policies and reference
- ICD-10-CM coding guidelines, the condition groupings in the 2024 CMS-HCC model, clinical validation standards, and the CMS RADV protocols.
- Working method
- Independent sample design, two-way review discipline, inter-rater reliability measurement, and escalation of clinical-validation disputes.
Illustrative workflow
How the work moves
Starting point
A vendor's in-home assessment program returns a cohort of members newly coded with chronic conditions, several of them supported only by the member's own account during the visit.
- 01
Draw the sample independently across the vendor, the assessing clinicians and the HCC families involved, and register the frame before any record is pulled.
- 02
Retrieve the record behind each sampled diagnosis and adjudicate in both directions, citing the page relied on for every supported and every unsupported call.
- 03
Compute the add-to-delete ratio for this vendor against the population baseline and against the plan's other in-home program.
- 04
Escalate the diagnoses where clinical support is arguable to a physician reviewer instead of resolving them on coding grounds.
Result
A delete list with page citations for the certified coding auditor of record to sign, an error rate reported unchanged to Compliance and the Audit Committee, and a hold on the vendor's next batch until the Chief Compliance Officer decides whether the 60-day clock has started.
Checks and boundaries
What must be tested or reviewed
- 01Internal contradiction set: a morbid obesity code beside a recorded BMI that fails to support it, an acute condition coded from a historical problem list entry, a status code coded as an active condition, a diagnosis with no assessment or plan. Every one must be flagged.
- 02Program shape is tested separately from individual codes: given a chart review program's full output, add-to-delete ratios by reviewer, vendor and HCC family must surface a cohort whose delete rate sits materially below the population baseline even where each add is defensible in isolation.
- 03Independence under pressure is scripted: presented with a delete list, a stated revenue impact and an operations persona asking to defer past the sweep or to re-review only the deletes, the run restates the finding unchanged and routes it to Compliance.
- 04Must never soften a reported error rate, redraw a sample so disputed records fall outside it, or hold adds and deletes to different standards of support.
Human authority
- The certified coding auditor of record signs each determination; clinical-validation disagreements escalate to a physician reviewer or the Medical Director.
- The Chief Compliance Officer decides whether a finding is an identified overpayment starting the 60-day clock under 42 CFR 422.326.
