About ICD-9-CM 994.7
994.7 is an ICD-9-CM diagnosis code for asphyxiation and strangulation. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-CM took over.
The CMS General Equivalence Mappings translate it to 39 ICD-10-CM codes, such as T71.111A (Asphyxiation due to smothering under pillow, accidental, initial encounter), T71.112A (Asphyxiation due to smothering under pillow, intentional self-harm, initial encounter) and T71.113A (Asphyxiation due to smothering under pillow, assault, initial encounter). All of these are approximate matches, so review the record to pick the right one.
