ICD-9 was published in 1979, however is modified every year. Though before ICD-9 there was a ICD-8 published in 1973. However many systems have been developed in the past, ICD started in1948 by WHO. Classification and coding started in England with John Graunt in the 17th century though it was not what ICD-9 is today.
The ICD-9-CM code for a bunion on the right big toe is 727.1. The ICD-9-CM codes for impetigo of the left eyelid are 684 and 373.5.
ICD-9-CM diagnosis code 599.72 is for Microscopic hematuria. (hematuria = blood in the urine)
The 100 ICD-9 codes all refer to Leptospirosis. As far as I can tell there is no 100.3 so I think you might be in error.

Wikipedia, ICD 9 codes online and ICD 9 coding websites all have free ICD 9 codes online. The CDC website also has information regarding ICD 9 codes.
One of the main differences between ICD-9 and ICD-10 is in the number of codes. ICD-9 has approximately 14000 diagnosis codes whereas ICD-10 has 68000. ICD-9 has 4000 procedural codes and ICD-10 has almost 72000. The nomenclature for these codes has also been modified in ICD-10. ICD-9 only had numeric code names, but ICD-10 will have alphanumeric code names. This naming convention will hopefully simplify matters by providing more accurate data for claim processing, clinical documentation, and research. ICD-10, which will be implemented in October will require coders to undergo training to familiarize themselves with the new coding practices. Several institutes, such as CareerStep offer training to students and professional coders who wish to upgrade their skill set to the new ICD-10-CM set of codes.
