2010 ICD-9-CM Diagnosis Code 355.9

Mononeuritis of unspecified site

Short description: Mononeuritis NOS.
ICD-9-CM 355.9 is a billable medical code that can be used to indicate a diagnosis on a reimbursement claim, however, 355.9 should only be used for claims with a date of service on or before September 30, 2015. For claims with a date of service on or after October 1, 2015, use an equivalent ICD-10-CM code (or codes).
You are viewing the 2010 version of ICD-9-CM 355.9.
