Verdict

The call

The clearest difference is in-app purchases: E/M Coder at none against ICD 10 Coding Guide's 1. E/M Coder also leads on update cadence (every 2 weeks vs every 12 months) and review sentiment (25% vs 17%). ICD 10 Coding Guide's advantage is rating (4.4 vs 4.0) and ratings volume (167 vs 8). On price, ads and device support there is nothing between them.

Both are free to download. ICD 10 Coding Guide sells 1 in-app purchase, starting at $9.99 per year. E/M Coder asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

ICD 10 Coding Guide holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: ICD 10 Coding Guide has 167 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 17% of ICD 10 Coding Guide's written reviews are positive against 25% of E/M Coder's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

ICD 10 Coding Guide ships an update every 12 months, E/M Coder every 2 weeks. The most recent releases landed on October 1, 2026 and September 27, 2026 respectively.
