When you pick codes it should automatically save in shortlist as physicians of a particular speciality use them again and again. ### 4/5 — Take it to new level *2010-08-29, version 0* Having icd9 on my itouch is great for searching codes and it works well. But there should be a settings tab in which a physician can select his speciality(ophthalmology , derm, etc or all). In case a particular speciality is selected then all codes appearing after that should be characterized and limited for billing of that particular speciality. ### 4/5 — useful *2010-08-08* very helpful for doctors. Category and keyword search works well. Please add CPT codes also to the app if possible so surgical codes are also added. That will also be very useful ### 4/5 — Question *2010-07-17, version 0* I just bought this app and the data looks good. The 2011 data comes out in October - what happens when that update comes out. Does that data get upgraded directly. Is there anything I would need to do on my end. Also is there any way I can make notes within the apps. If not, I would recommend that as a desirable feature for the future. ### 4/5 — group codes classification *2010-06-28, version 0* I have been using this for a few months for my opthalmology residency and have since not used the icd9 book. what I need is to be able to group all opthalmology codes I use in a single group, internal medicine in a different group and so on. that will make a big diff to the app ### 1/5 — WORTHLESS APP!!! Messes up your iphone!! *2010-06-01, version 0* WORTHLESS! It took several tries to download (over two days). Once it downloaded, it made my iphone stall, and would nto open properly for use. After several attempts trying to get it to work, I deleted the app and my iphone no longer acted as if it has a virus. Waste of money. There are several icd-9 apps out there for free that work great. And if you are in the saem boat as I am, good luck at getting a refund. Itunes takes you to the developer website, and from there it is a dead end. ### 1/5 — Poor app *2010-05-23, version 0* Every time I use it, it always eventually crashes. Very poor app. ### 4/5 — Good Update *2010-04-22, version 0* Search works well now .Please also add a nodesfield. ### 4/5 — Search works great now with new update *2010-04-22, version 0* It took me a while to figure out but u need to uninstall and reinstall the search. Came in real handy. I also need something for CPT ### 4/5 — Feature Requested *2010-04-22, version 0* Works well. Can u package HCPCS as part of the app and not seperately ### 1/5 — Too many bugs *2010-04-21, version 0* Not worth the price. It's slow and crashes. Search is garbage. Doesn't give you 4th or 5th digit warnings. Everytime I contact the company they say reinstall the app... Please are you serious. This app is garbage. Use something else but not this. ### 1/5 — RN *2010-04-21, version 0* Positive reviews are suspect. Update does not help. Search function is awful. Crashes after each search. Buyer beware! ## Most critical reviews (10 lowest-rated) ### 1/5 — Search function doesn’t work *2022-07-12* I just bought this app, largely for the search function but it does not work. I do not recommend this app if you’re hoping to search for icd codes by disease. I’m deleting it. ### 1/5 — Forget it! *2012-12-29, version 3.1* Charged 3.99 for 2 categories then want 3.99 for more! That's not satisfactory! Buy a different app! ### 1/5 — Not worth It!! *2012-12-13, version 3.1* I bought this app for $3.99...now it says I have to pay another $3.99 to use the full search function...I have asked for my money back...Hopefully someone reads the email!!!! ### 1/5 — Worst purchase ever!!!! *2011-04-05, version 2.3* Slow slow slow slow...not up to date, I WANT MY MONEY BACK!!!!! ### 1/5 — Worthless *2010-09-26, version 0* I would NOT recommend. ### 1/5 — disappointed Big TIME!! *2010-09-21, version 0* I was very disappointed with this app. No search......are you kidding me! Very brief descriptions. No cross coding. You get very little. Practically useless to me. Sorry but I wish I hadn't bothered. App needs lots of work to be useful. ### 1/5 — not worth the 99 cents *2010-09-14, version 0* Starts out looking like it will work...then crashes consistently. ### 1/5 — Surgeon *2010-08-18, version 0* Terrible app. Graphics are great bit the search function did not work and the program would not give the codes to any degree past the decimal point. I ended up deleting it. ### 1/5 — Waste of $$. Wikipedia is free. *2010-07-07, version 0* I'm tired of this app working then not working again. While not working I've come to find that Wikipedia has all the same information for FREE, just search under "List of icd 9 codes". I now have a little more free memory on my iphone. ### 1/5 — Pediatrician *2010-07-03, version 0* Don't buy this app!!! I want to give it 0 star if I can. The search function doesn't work and the specific list of codes I need for billing aren't even there. I can't believe they charge for this worthless app. I went back to using the free web site and am searching for another iPhone app. ## Most praised reviews (10 highest-rated) ### 5/5 — Nice! *2010-10-17, version 0* Very convenient for codes and billing. ### 5/5 — It's all rite...... *2010-09-26, version 0* App works as advertised, definitely recommended...... ### 5/5 — Wonderful Customer Service *2010-07-25* Gagan, thank you very much for all you help. The app works now. Keep the good work up. ### 5/5 — ICD Codes *2010-04-22, version 0* The Codes are good and I like the App. But to go back between HCPCS and ICD9 we have to log into separate Apps. It will be better to allow searching within same App. This will make my life easier ### 5/5 — The new update is perfect. Everything works *2010-04-22, version 0* I really needed this. All errors fixed. ### 5/5 — Great... *2010-04-18, version 0* Best ever application for Iphone. ### 5/5 — Good Job *2010-04-16, version 0* Codes are good. Good Job ### 5/5 — Great app *2010-04-12, version 0* We really like it ### 5/5 — App is useful *2010-04-10, version 0* I won't mind paying more for the App in case you add CPT as well. ### 5/5 — New version works well !! *2010-04-08, version 0* The updated version works well.
