Version 2020 Billable Code No Valid Principal Dx

Valid for Submission

R89.6 is a billable code used to specify a medical diagnosis of abnormal cytological findings in specimens from other organs, systems and tissues. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code R89.6 might also be used to specify conditions or terms like abnormal cytology findings, aggregation, aggregation, aggregation, barr body absent, nuclear sex male, barr body present, nuclear sex female, 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.
