Changes to the ICD-10-CM Official Guidelines for Coding and Reporting

Why This Topic Matters

Guideline updates can affect diagnosis sequencing, reporting practices, and documentation review workflows. Staying aware of these changes helps coding and compliance staff interpret the current ICD-10-CM framework accurately and recognize when full guideline review is needed.

Article Sections

1. C. Chapter Specific Coding Guidelines

   Overview of selected chapter-specific updates within the ICD-10-CM guidelines. The section organizes changes by chapter and clinical topic.

2. Chapter 1: Certain Infectious and Parasitic Diseases (A00-B99), U09.9

   Updates related to infectious disease guidance within Chapter 1. The section includes discussion of sepsis-related coding topics and a referenced diagnosis code.

3. d. Sepsis, Severe Sepsis, and Septic Shock Infectious resistant to antibiotics

   Focused guidance within the sepsis subsection. This portion addresses postprocedural infection scenarios and related sequencing considerations at a high level.

4. 5) Sepsis due to a postprocedural infection

   A narrower update within the sepsis guidance hierarchy. The section addresses coding considerations tied to sepsis after procedures and related documentation needs.

5. (b) Sepsis due a postprocedural infection

   Specific guidance under the postprocedural sepsis topic. The section discusses how the guideline addresses infection source reporting, additional organism identification, and related severity considerations.

6. Chapter 4: Endocrine, Nutritional, and Metabolic Diseases (E00-E89)

   Updates within the endocrine and metabolic chapter. The material focuses on secondary diabetes mellitus and a postsurgical condition tied to pancreatic removal.

7. a. Diabetes mellitus

8. 6) Secondary diabetes mellitus

   Guidance addressing secondary diabetes coding within the diabetes section. The update centers on causes and related code assignment structure.

9. (b) Assigning and sequencing secondary diabetes codes and its causes

   Subsection covering how secondary diabetes and its underlying causes are discussed in the guideline update. The text focuses on a postsurgical diabetes scenario.

10. (i) Secondary diabetes mellitus due to pancreatectomy

    Specific topic related to diabetes occurring after pancreatic surgery. The section addresses a postsurgical endocrine condition and associated additional coding context.

11. Chapter 21: Factors influencing health status and contact with health services (Z00-Z99)

    Updates involving Z codes and factors influencing health status. The section includes aftercare-related guidance and therapy-visit exceptions.

12. c. Categories of Z codes

    General Z code category guidance within Chapter 21. The section frames the aftercare material and its exceptions.

13. 7) Aftercare

    Guidance on aftercare visit coding in the context of healing, recovery, and long-term consequences. The section also notes exceptions related to certain therapy encounters.
