Not easy to use, missing codes, missing ADHD

This is not user friendly, missing codes such as 314.02, missing abbreviations such as ADHD, you have to spell out attention etc. I bought this app accidentally and currently it's inferior compared to free app I downloaded called quick icd10.

Developer Response ,

Thanks for taking the time to review our app. After investigating, we found 314.02 was not a valid code, the code that you wanted was 314.01 according to the last release of the ICD-9 coding. It is true that we do not create common abbreviations but only use the data as distributed by CMS. As of 2.0, you can now use a partial search such as "ATTEN HYPER" and easily locate both the old ICD-9 codes as well as the current ICD-10 coding. We may consider adding common abbreviations if we can locate a trustworthy source of abbreviation mappings.
