Four HCCs drew the government’s attention in the Monogram Health settlement

The Department of Justice (DOJ) on Aug. 24 announced Monogram Health Professional Services will pay $2.4 million to resolve False Claims Act allegations involving diagnosis codes submitted for Medicare Advantage (MA) beneficiaries. The settlement resolves allegations only, with no determination of liability.

Monogram, based in Tennessee, sends clinicians into members’ homes to manage complex chronic conditions, including kidney disease. The company worked under risk-based contracts with MA plans, including Cigna and Humana, according to Healthcare Dive. About $1.4 million of the settlement is restitution. The alleged conduct ran from January 2021 through December 2023.

Set the dollar figure aside. Next to the $581 million valuation across the Kaiser-related resolutions, $2.4 million barely registers. The useful part of this case sits in the detail: the government named the exact hierarchical condition categories (HCCs) at issue, and the case started with a physician working inside the program.

The four categories at issue

HCC 21, protein-calorie malnutrition. Federal auditors have circled malnutrition coding for years. A 2020 HHS Office of Inspector General (OIG) report found hospitals overbilled Medicare about $1 billion by incorrectly assigning severe malnutrition codes to inpatient claims. The category carries real weight in the risk model and often rests on thin documentation.

HCC 55, substance use disorder. This category also appeared in the Complete Health settlement DOJ announced three weeks earlier, on Aug. 3, alongside HCC 59. Two provider-side coding settlements in one month, both touching the same behavioral health territory.

HCC 48, coagulation defects and other specified hematological disorders. A category frequently captured from a single lab value or a historical mention, with little in the record showing the condition under management.

HCC 88, angina pectoris. A symptom-level cardiac code with a documentation trail thinner than the coronary disease diagnoses around it.

DOJ said the codes at issue were unsupported by the medical records and did not require or affect patient care. Read that phrase closely, because it doubles as a review standard. Does the record show the condition being managed after the diagnosis was captured?

The case came from inside the program

Dr. Ajay Gupta, a physician formerly employed by Monogram, filed the qui tam suit in 2022 in the U.S. District Court for the Central District of California. His share of the recovery comes to about $380,000.

Pair that with the Complete Health case, where a former associate director of risk adjustment at a health plan filed the underlying suit. Neither case surfaced through a RADV audit or a federal data-mining project. Both started with a clinician or a risk adjustment professional who noticed a pattern at work.

What this means for health plans

Plans answer to CMS for every diagnosis submitted, including diagnoses captured by delegated partners at a member’s kitchen table. In-home assessment programs exist to find undocumented conditions, so a high yield of new diagnoses per visit is the design working as intended. The oversight question is narrower: does the plan see enough of the vendor’s output to recognize an outlier?

The financial backdrop keeps federal attention on the answer. MedPAC estimated Medicare will pay MA plans $76 billion more in 2026 than the same beneficiaries would cost in fee-for-service, with coding intensity driving a large share of the gap.

Most plans already audit vendor coding in some form, so the build ahead is a refinement rather than a rebuild. Prevalence comparisons by vendor, by provider group, and by HCC. A documented look at the categories the government keeps naming. A record of what the organization did once a pattern appeared. The conduct alleged here spanned three years before it reached a courtroom, which means plans strengthening oversight now are writing the record a future reviewer reads.

Questions to consider

  • Do your analytics compare HCC prevalence by vendor and by provider group, or only at the plan level?
  • How often do the four categories named in this case appear in your in-home assessment data, and how does the rate compare with your provider network?
  • When a diagnosis arrives from a home visit and no treatment claim follows, does anything in your workflow flag it?
  • Do your delegated and risk-sharing contracts spell out audit rights over coding decisions and the documentation behind them?
  • Where would a clinician inside one of your vendor programs take a coding concern, and who would act on it?

RISE takes on RADV defense, documentation integrity, and vendor oversight at the 27th Risk Adjustment Forum, October 27-29, in Orlando, including a live audit simulation and sessions on revenue integrity and AI governance in coding operations. Sooner, risk adjustment litigation trends and OIG oversight priorities are on the agenda at RISE West 2026, September 2-4, in San Diego.
