No, probably not. Most apps aren't maintained and updated as regularly as something like ICD would need to be. And it's a huge amount of data, actually. I wouldn't trust one unless it was managed by a large well-known, reputable industry organization such as AAPC, Optum, AHIMA, etc.
There are free websites that can do what you are looking for, and will work fine on a phone screen environment. Have you tried ICD10Data.com yet?
http://www.icd10data.com/ Give that one a look. Very easy to navigate, very robust, updated regularly as ICD changes are posted. Very smartphone friendly. There are links for ICD10-CM, ICD10-PCS, will link over to HCPCS codes, has the indexes, the neoplasm and drug tables, etc. Even has a ICD9 to ICD10 conversion tool. You can search it just like you would from your book. Great resource to keep open while coding, when you just want a quick lookie at the section rules, or to make sure you're using a familiar code in the correct manner, etc.
Now, it doesn't have the full guidelines. Keep in mind this is only a TOOL to help. It is not a replacement for your coding book! But it is a great tool to use as a compliment to your books, or when you just need a quick look to confirm a coding situation on the fly.
