Insulin dependent diabetes mellitus (IDDM), also known as type 1 diabetes, usually starts before 15 years of age, but can occur in adults also.
Type I diabetics require the use of insulin to live. The use of insulin is implied in the diagnosis of Type I diabetes itself. Since this is the case, it is not necessary to report a Z code for long-term insulin use because it would be understood that this patient would be using insulin.

ICD-9-CM is the official system of assigning codes to diagnoses and procedures associated with hospital utilization in the United States. The ICD-9 was used to code and classify mortality data from death certificates until 1999, when use of ICD-10 for mortality coding started.
Chapter 16 of ICD-9-CM, Symptoms, Signs, and Ill-defined conditions (codes 780.0 - 799.9) contain many, but not all codes for symptoms.
The conventions for the ICD-9-CM are the general rules for use of the classification independent of the guidelines. These conventions are incorporated within the index and tabular of the ICD -9-CM as instructional notes. The conventions are as follows:
When coding the birth of an infant, assign a code from categories V30-V39, according to the type of birth. A code from this series is assigned as a principal diagnosis, and assigned only once to a newborn at the time of birth.
If a patient is documented as having both MRSA colonization and infection during a hospital admission, code V02.54, Carrier or suspected carrier, Methicillin resistant Staphylococcus aureus, and a code for the MRSA infection may both be assigned.
