2. 2.4 ICD-9-CM Chapter-Specific Guidelines (continued) Chapter-Specific Guidelines for ICD-9-CM: 1.Infectious and Parasitic Diseases: Guidelines are specific and concern coding of HIV, septicemia, SIRS, sepsis, and MRSA. Guidelines include selection and sequencing instructions specific to these conditions. 2.Neoplasms: Guidelines pertain to general guidelines for reporting neoplasms and sequencing instructions pertaining to history of malignant neoplasm, administration of chemotherapy, radiotherapy, and complications due to the condition or therapy. 3.Endocrine, Nutritional, and Metabolic Diseases and Immunity Disorders: Guidelines for diabetes. Codes in this chapter require fifth digits. There are also multiple-sequencing guidelines, including those on the use of slanted brackets (etiology/manifestation sequencing). 2-17
