ICD-10-CM Code R94.8

Abnormal results of function studies of other organs and systems

Version 2021 Billable Code No Valid Principal Dx

Valid for Submission

R94.8 is a billable code used to specify a medical diagnosis of abnormal results of function studies of other organs and systems. The code is valid for the fiscal year 2021 for the submission of HIPAA-covered transactions. The ICD-10-CM code R94.8 might also be used to specify conditions or terms like basal metabolic rate - finding, basal metabolic rate outside reference range, cystometry abnormal, decreased amniotic fluid production, decreased placental secretion of chorionic gonadotropin, digestive function test abnormal, etc

According to ICD-10-CM guidelines this code should not to be used as a principal diagnosis code when a related definitive diagnosis has been established.
