HCC / Risk Adjustment Coding
HCC Coding and Risk Adjustment Services That Capture Every Diagnosis You’ve Earned
Undercoded Patients Cost You. Accurate HCC Coding Pays You Back.
In risk-based healthcare, your reimbursement is only as accurate as your documentation and coding. MedixCode’s HCC coding and risk adjustment services ensure that every chronic condition, every qualifying diagnosis, and every patient encounter is coded with the specificity and completeness that your RAF scores depend on compliantly, consistently, and at scale.
Why It Matters
Why Risk Adjustment Coding is a Revenue Imperative
The shift toward value-based care has fundamentally changed the economics of healthcare. Under Medicare Advantage and other risk-based payment models, your capitated reimbursement is not fixed, it is calculated. It rises and falls based on how accurately your patient population’s true health burden is reflected in the diagnosis data you submit.
That calculation runs through Hierarchical Condition Categories (HCCs). The Centers for Medicare & Medicaid Services uses HCC coding to establish risk adjustment factors for each patient, which in turn determine the per-member per-month payment your plan or provider organization receives. Patients with multiple chronic conditions, complex comorbidities, and high-acuity diagnoses carry higher RAF scores. Higher RAF scores generate higher capitation payments.

MedixCode closes gap. Our HCC risk adjustment coding services combine certified coding expertise, systematic chart review methodology, and a compliance-first approach to ensure that every valid, documented diagnosis is accurately captured, every qualifying HCC is mapped, and your RAF scores reflect the reality of the patients you serve.
Full-Service HCC Coding
Explore Our Advanced HCC Coding and Risk Adjustment Services
Six specialized workflows that make your risk adjustment program complete — from prospective chart review through RADV audit defense.
01
Prospective HCC Coding and Chart Review
MedixCode’s prospective coding team reviews member records in advance of scheduled encounters, identifies previously mapped HCCs that require annual recapture, and surfaces undiagnosed or undercoded conditions supported by the clinical evidence in the record.
In addition, we prepare structured summaries that give providers the clinical context they need to address and document those conditions during the visit. The result is a more complete encounter and a RAF score that accurately reflects the patient’s documented health status.

02
Retrospective HCC Coding and Gap Closure
MedixCode conducts systematic retrospective chart reviews across your Medicare Advantage population, prioritizing members with known chronic conditions, high utilization patterns, and coding gaps identified through prospective analysis.
Furthermore, we capture diagnosis codes supported by the clinical documentation and submit them through the appropriate risk adjustment data submission pathways, helping recover RAF score value that would otherwise be permanently lost.

03
RAF Score Analysis and Optimization
Understanding where your RAF scores stand and why, is the starting point for any meaningful risk adjustment strategy. MedixCode provides detailed RAF score analysis that benchmarks your current member-level risk scores against expected values based on demographic profiles and known clinical conditions, identifies systematic coding gaps by provider, site of care, and condition category, and quantifies the revenue impact of those gaps in terms of annual capitation.
04
Medicare Advantage Risk Adjustment Coding
We manage the full coding workflow for Medicare Advantage risk adjustment, from chart review and diagnosis capture through quality review, submission file preparation, and ongoing performance monitoring. Our team tracks CMS model updates and adjusts coding and submission strategies accordingly, ensuring your risk adjustment program remains optimized through every model year.
05
HCC Coding for Value-Based Care Contracts
Risk adjustment is not exclusive to Medicare Advantage. Commercial risk-based contracts, ACO participation, and Medicaid managed care arrangements increasingly incorporate risk adjustment mechanisms that reward accurate diagnosis capture and penalize coding gaps.
MedixCode supports HCC coding programs across a range of value-based care arrangements, tailoring the coding methodology to the specific model in use, CMS-HCC, HHS-HCC for commercial plans, or proprietary payer models.

06
RADV Audit Preparation and Defense
MedixCode provides RADV audit preparation services that review your highest-RAF members and highest-risk HCC categories for documentation adequacy before CMS initiates an audit.
We identify diagnoses that may not survive medical record review, work with your clinical documentation team to strengthen supporting records where clinically appropriate, and prepare your organization to respond to audit requests with confidence and completeness.

Common Coding Gaps
The Most Common HCC Coding Gaps, and What They Cost
Most risk adjustment programs have the same categories of coding gaps. Recognizing them is the first step to addressing them.
01
Chronic conditions not recaptured annually.
A diagnosis of COPD that was coded in 2023 but not in 2024 does not contribute to the 2024 RAF score. Systematic annual recapture is the operational backbone of a functioning risk adjustment program.
02
Specificity gaps in ICD-10-CM coding.
Diabetes coded as E11.9 (type 2 diabetes without complications) does not map to the same HCC as diabetes with chronic kidney disease (E11.65) or diabetic neuropathy (E11.40). Coding at the unspecified level when the record supports more specificity is both a revenue loss and a documentation inaccuracy.
03
Comorbidities present but not coded.
Patients with complex chronic conditions frequently have secondary diagnoses that are documented in the clinical record but not assigned as coded diagnoses. Each uncoded instance is lost RAF value.
04
Inconsistent coding across care settings.
A diagnosis captured by a specialist may not be reflected in the primary care record. A hospital discharge code may not be carried forward into the outpatient chart. Without a coordinated coding program that spans care settings, these gaps accumulate.
Compliance First
Compliance is Not a Constraint. It is the Foundation
MedixCode operates from a compliance-first framework. Every diagnosis we capture must be documented in the medical record, coded in accordance with ICD-10-CM Official Guidelines, and submitted through the appropriate data pathways.
We do not infer diagnoses.
We do not code from problem lists that are not reflected in the clinical narrative.
We do not submit diagnoses that a provider has not assessed and documented in the current period.
Our internal quality review process validates every coded diagnosis against the source documentation before submission.
We maintain coding audit trails, document our review methodology, and provide clients with the transparency they need to defend their risk adjustment submissions under regulatory review.

FAQs
Frequently Asked Questions
Common HCC and risk adjustment coding questions we hear from health plans and provider organizations.
What is an HCC and how does it affect Medicare Advantage reimbursement?
A Hierarchical Condition Category is a diagnosis group used by CMS to quantify the expected healthcare cost burden of a Medicare Advantage enrollee.
How often do HCC diagnoses need to be coded for risk adjustment?
CMS requires that HCC-qualifying diagnoses be present in the risk adjustment data submission for the current payment year. Annual recapture of chronic conditions is one of the most impactful elements of a well-functioning risk adjustment program.
What is the difference between prospective and retrospective HCC coding?
Prospective coding occurs before or during the care encounter, identifying conditions that need to be addressed and documented in the current visit. Retrospective coding reviews completed encounters for diagnoses that were present in the clinical record but not captured.
How does MedixCode ensure its HCC coding is compliant?
Every diagnosis captured by MedixCode must be documented in the medical record, coded in accordance with ICD-10-CM Official Coding Guidelines, and reviewed by our internal quality team before submission.
Can MedixCode help us prepare for a RADV audit?
Yes. MedixCode provides dedicated RADV audit preparation services that review your highest-risk submissions for documentation adequacy and prepare your organization to respond to CMS record requests with confidence.
