Multiple Endocrine Neoplasia (MEN)

Why This Topic Matters

MEN syndromes are rare and can involve multiple endocrine glands, so accurate classification affects diagnosis reporting and linkage to associated conditions. This update is important for anyone coding endocrine disorders under ICD-9-CM during the transition to the new MEN-specific code family.

Article Sections

1. Background and rationale for the coding change

   Introduces the MEN topic and explains why the earlier classification did not fully capture these syndromes. It also identifies the timing of the update.

2. Overview of MEN syndromes

   Describes MEN as a group of rare inherited endocrine syndromes and notes the general forms recognized in the article. Broad clinical features and terminology are summarized.

3. MEN type I

   Summarizes the first MEN subtype and the major endocrine systems involved. Associated findings mentioned in the article are included at a high level.

4. MEN type IIA

   Summarizes the second MEN subtype and its broad clinical associations. The section focuses on the syndrome presentation rather than coding specifics.

5. MEN type IIB

   Summarizes the third MEN subtype and the general associated abnormalities noted in the article. It provides a broad overview of the syndrome features.

6. Coding guidance and code structure update

   Explains the revised diagnosis category structure and notes that related conditions may need to be reported separately. It also points readers to family history and genetic susceptibility information elsewhere in the issue.

7. Clinical example

   Presents an example case involving MEN and an associated malignant condition to illustrate the topic of coding for related diagnoses.
