As of October 2015, ICD-9 codes are no longer used for medical coding. Instead, use this equivalent ICD-10-CM code, which is an approximate match to ICD-9 code 715.36:
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
715.36 is a legacy non-billable code used to specify a medical diagnosis of osteoarthrosis, localized, not specified whether primary or secondary, lower leg. This code was replaced on September 30, 2015 by its ICD-10 equivalent.
The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.
