Previously neuroendocrine tumors (NETs) were called carcinoid tumors and some clinicians will continue to call them carcinoid tumors. This is a physician query opportunity.
They are not universally consistent in their characteristics. Some neuroendocrine cancer grows quickly while others grow slowly. Most of these tumors develop in the lungs, appendix, small intestine, rectum, testicles, ovaries, and pancreas, but and essentially, can be found anywhere. Some tumors can produce hormones, while others don’t. Symptoms may vary depending on the part of the body affected by the tumor.[i] They are comprised of cells that may produce hormonal syndromes which impact the normal hormonal balance that supports body system functions.
NETs can be malignant or benign. Unfortunately, the clinical documentation we see as coders, does not always clearly specify malignant or benign. So, here’s another physician query opportunity! If the documentation does not specify the NET as malignant or benign, the default is benign. This path to benign is per the indexing of tumor, neuroendocrine: D3A.8-Other benign carcinoid tumors
Often this neuroendocrine tumor is abbreviated in the documentation. Look for NET or other abbreviations such as PNET or PanNET for pancreatic NET, GINET for gastrointestinal NET, and WDNET or PD NET for well-differentiated or poorly-differentiated neuroendocrine tumor.
IMPORTANT: Neuroendocrine tumors have their own set of codes. They are not coded from the neoplasm table codes. I can’t explain the logic for not including them in the table!
These tumors arise from epithelium; thus, malignant tumors in this group are referred to as neuroendocrine carcinomas.[ii] NETs can spread to the bones, brain, lungs, and other locations. The type and location of the cancer influences the treatments. Treatment may include surgery, radiation, targeted therapy, or a combination of these treatment techniques. Finally, many of the tumors in the categories above yield an HCC and some a RxHCC.
If you remember one thing about NETs, it’s to NOT use the neoplasm table. Coders and clinical documentation integrity specialists play a vital role in accurately capture the documentation needed to apply a specific code for NETs and help future clinicians prepare an appropriate care plan for the patient.

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.
Sepsis remains one of the most frequently denied and contested diagnoses, creating costly revenue loss and compliance risks. In this webcast, Angela Comfort, DBA, MBA, RHIA, CDIP, CCS, CCS-P, provides practical, real-world strategies to align documentation with coding guidelines, reconcile Sepsis-2 and Sepsis-3 definitions, and apply compliant queries. You’ll learn how to identify and address documentation gaps, strengthen provider engagement, and defend diagnoses against payer scrutiny—equipping you to protect reimbursement, improve SOI/ROM capture, and reduce audit vulnerability in this high-risk area.
