PRINCIPLE XVIII. SPECIAL DIAGNOSIS
1. Viral (Infectious) Hepatitis.
a. The code numbers in ICD-9-CM for viral hepatitis will be used. However, to
provide greater specificity for DOD use, this category has been expanded by use of
DOD code extenders, which are included in Appendix A of the Triservice Disease and
Procedure Coding Guidelines , dated 1 January 1991.
b. There is no longer a requirement to denote drug use/nonuse when coding
c. Post-transfusion hepatitis will be coded 999.8 and 7.3--1.
d. Post-vaccination hepatitis will be coded 999.9 and 7.3--1.
2. Diabetes Mellitus.
a. Category 25 is used to classify diabetes mellitus. Fourth-digit classifications
are used to identify the presence of coma or systemic manifestations. The fifth-digit
subclassifica-tion will specify the type of diabetes. When the physician does not specify
the type of diabetes, a fifth digit of "" is assigned.
-- Adult onset and NOS (AODM)
Noninsulin Dependent Diabetes (NIDDM)
Maturity Onset Diabetes (MODM)
Type II Diabetes
1 -- Juvenile type (JO DM)
Insulin Dependent Diabetes (IDDM)
Adult Onset with Insulin Dependence
Type I Diabetes
b. To use the fifth digit of "1," insulin dependent must be noted somewhere in the
medical record or as part of the stated final diagnosis. Do not assume a patient has
insulin dependent diabetes simply because the patient is receiving insulin. Sometimes
Type II diabetics require temporary use of insulin when they are hospitalized for surgery
or other illness. Consult the physician for clarification in such cases.
c. System Manifestations.
(1) Categories 25.4-25.8 are used to classify diabetes with systemic
manifestations, which represent a cause and effect relationship with the diabetes.
These codes are presented together as an inseparable pair in the Alphabetic Index.
These paired codes are sequenced so that the underlying cause (diabetes) is always
positioned first and followed by the manifestation code.
