New CMS document features gems that fill risk adjustment voids for coding rules.
Coders love rules. In risk adjustment coding, we live by the Official Guidelines for Coding and Reporting, the ICD-10-CM conventions for code lookup, and the AHA Coding Clinic for ICD-10-CM and ICD-10-PCS. Too often, though, we run into situations in which there are no rules, or when guidance is sketchy. Because diagnoses translate into revenue in risk adjustment, employers usually develop and maintain internal coding policies to provide rules where none exist. And they long for official advice from the Centers for Medicare & Medicaid Services (CMS).
Without fanfare, CMS published a 56-page document entitled Contract-Level Risk Adjustment Data Validation Medical Record Reviewer Guidance late last year. Within this painstaking document are some gems that fill risk adjustment voids for coding rules. For example, Review Guidance offers the following advice regarding problem lists within a medical record:
This simple entry packs quite a punch! We have all been taught that problem lists are not acceptable sources for risk adjustment coding, yet CMS instructs auditors to evaluate a diagnosis from a problem list on a case-by-case basis, even if the list is auto-populated within an EMR.
According to the Review Guidance, problem list diagnoses are evaluated based on “chronicity and support in the full medical record, such as history, medications, and final assessment.” By chronicity, CMS is differentiating between chronic, incurable conditions (e.g., diabetes, multiple sclerosis) and acute conditions (e.g., pneumonia, sepsis). CMS also directs auditors to seek out information elsewhere in the record that may validate a problem list diagnosis. This might include a medication (e.g., “metformin” for diabetes) or history of present illness (e.g., “patient’s blood sugars are in control despite cellulitis”).
This new guidance on problem lists has some organizations scratching their heads on whether coders should begin reporting these problem-list diagnoses. That’s an organizational choice, because while revenues may be raised by including these diagnoses, the possibility of negative outcomes during an RADV also rise. Remember, CMS auditors are given discretion on whether to accept these problem list diagnoses. Normally, these would be reported only as last-ditch efforts to validate a reported code in an RADV audit.
The Review Guidance also clarifies how auditors should treat codes substituted for diagnosis narratives in documentation:
Thus, if “E10.65 Diabetes” is documented, the coder abstracts using the narrative (“Diabetes”) rather than from the diagnosis represented by the code (type 1 diabetes with hyperglycemia). Correct reporting for “E10.65 Diabetes” is E11.9, Type 2 diabetes mellitus without complication.
A solid CDI program is a better approach to under-documentation.

Sepsis sequencing continues to challenge even experienced coding and CDI professionals, with evolving guidelines, documentation gaps, and payer scrutiny driving denials and data inconsistencies. In this webcast, Payal Sinha, MBA, RHIA, CCDS, CDIP, CCS, CCS-P, CCDS-O, CRC, CRCR, provides clear guideline-based strategies to accurately code sepsis, severe sepsis, and septic shock, assign POA indicators, clarify the relationship between infection and organ dysfunction, and align documentation across teams. Attendees will gain practical tools to strengthen audit defensibility, improve first-pass accuracy, support appeal success, reduce denials, and ensure accurate quality reporting, empowering organizations to achieve consistent, compliant sepsis coding outcomes.
Expert presenters Kathy Pride, RHIT, CPC, CCS-P, CPMA, and Brandi Russell, RHIA, CCS, COC, CPMA, break down complex fracture care coding rules, walk through correct modifier application (-25, -57, 54, 55), and clarify sequencing for initial and subsequent encounters. Attendees will gain the practical knowledge needed to submit clean claims, ensure compliance, and stay one step ahead of payer audits in 2026.
Accurately determining the principal diagnosis is critical for compliant billing, appropriate reimbursement, and valid quality reporting — yet it remains one of the most subjective and error-prone areas in inpatient coding. In this expert-led session, Cheryl Ericson, RN, MS, CCDS, CDIP, demystifies the complexities of principal diagnosis assignment, bridging the gap between coding rules and clinical reality. Learn how to strengthen your organization’s coding accuracy, reduce denials, and ensure your documentation supports true medical necessity.
Denials continue to delay reimbursement, increase administrative burden, and threaten financial stability across healthcare organizations. This essential webcast tackles the root causes—rising payer scrutiny, fragmented workflows, inconsistent documentation, and underused analytics—and offers proven, data-driven strategies to prevent and overturn denials. Attendees will gain practical tools to strengthen documentation and coding accuracy, engage clinicians effectively, and leverage predictive analytics and AI to identify risks before they impact revenue. Through real-world case examples and actionable guidance, this session empowers coding, CDI, and revenue cycle professionals to shift from reactive appeals to proactive denial prevention and revenue protection.
In this timely session, Stacey Shillito, CDIP, CPMA, CCS, CCS-P, CPEDC, COPC, breaks down the complexities of Medical Decision Making (MDM) documentation so providers can confidently capture the true complexity of their care. Attendees will learn practical, efficient strategies to ensure documentation aligns with current E/M guidelines, supports accurate coding, and reduces audit risk, all without adding to charting time.
