ICD-10 Top 25 Diagnoses

For months, providers around the country and all around northern Michigan have been ramping up their documentation, completing specialized training, and preparing themselves and their staff for ICD-10. For all providers, the transition on October 1, 2015 will have a significant and lasting impact. For those who diagnose and document some of the most common conditions, the impact may be felt with the very first patient.

Based on a review of outpatient services at Munson Medical Center over the last 18 months, here are 10 of the top 25 most common ordering diagnoses affected by ICD-10. Coding for all these diagnoses will change under ICD-10, some more than others, so complete and accurate documentation is critical.

Providers are encouraged to use the list below as a starting point to begin translating the codes to their new ICD-10 equivalents.
