ICD-10-CM Code R55

Valid for Submission

R55 is a billable code used to specify a medical diagnosis of syncope and collapse. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code R55 might also be used to specify conditions or terms like anoxic seizure, brief loss of consciousness, collapse, collapse, complex part seizure with impairment of consciousness only, complex partial seizure + impairment consciousness at onset, etc

The code is commonly used in cardiology medical specialties to specify clinical concepts such as syncope and collapse.

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.

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

• Blackout
• Fainting
• Vasovagal attack

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
