We used existing guidelines and best practices of diagnosis coding to 
develop a dedicated Medicare Risk Adjustment webpage to assist our 
providers in accurately coding and documenting diagnoses for our Medicare 
Advantage members.
Risk adjustment
Risk adjustment is a process of collecting all diagnosis codes from patient 
charts and using the documented illnesses, comorbidities, and complications to 
determine a risk score. Risk scores are used to illustrate a need for higher 
reimbursement rates for patients who have more serious health conditions to 
manage.
Clinical documentation improvement
Clinical documentation improvement is a process used to improve 
documentation so that a patient’s clinical status is accurately 
represented in coded data.

Independence Blue Cross coding and documentation 
education materials are based on current guidelines, are to be used for 
reference only, and are not intended to replace the authoritative guidance of 
the ICD-10-CM Official Guidelines for Coding and Reporting as approved by the 
American Hospital Association (AHA), the American Health Information Management 
Association (AHIMA), Centers for Medicare & Medicaid Services (CMS), and 
the National Center for Health Statistics (NCHS). Clinical and coding decisions 
are to be made based on the following: 
1. The independent judgment of the treating physician or qualified health care 
practitioner.
2. The best interests of the patient.
3. The clinical documentation as contained in the medical record.
