Same with me, many but not all left sided diagnoses (by code number, often ending in 2) state bilateral. Many other errors in ICD10 descriptions, such as left or right shoulder pain only being available as "radiating to" shoulder, etc, etc, etc. Also lack of many, if not most, standard short or long descriptions for ICD 10 codes. I, also, am still using version 8.2.4 (scared off by problems with restoring 9+ versions to another computer, as in event of hardware failure).
