ICD 10 Coding Alert


3 Characters in ICD-10 Take the Place of Syncope Code 780.2

Check out the Excludes1 note to keep your coding on track.

Learning ICD-10’s replacement for syncope code 780.2 shouldn’t put a hitch in your implementation plan because you’ve got a one-to-one code swap to look forward to. Read on for tips to ensure you use the ICD-10 code properly.

ICD-9-CM Code

780.2, Syncope and collapse

ICD-10-CM Code

R55, Syncope and collapse

Syncope is a temporary loss of consciousness caused by a fall in blood pressure.

ICD-9 coding rules: The ICD-9 Tabular List indicates 780.2 applies to: blackout, fainting, (near) (pre)syncope, and vasovagal attack. But an Excludes note points you elsewhere for carotid sinus syncope (337.0), heat syncope (992.1), neurocirculatory asthenia (306.2), orthostatic hypotension (458.0), and shock NOS (785.50).

ICD-10 changes: The ICD-10 Tabular List features a list of terms for R55 that’s similar to what you see in ICD-9: blackout, fainting, and vasovagal attack. Although the Tabular doesn’t list “(near) (pre)syncope” for R55, the Index does. The code also has a long Excludes1 list:

  • Hypotension: neurogenic orthostatic (G90.3), orthostatic (I95.1)
  • Neurocirculatory asthenia (F45.8)
  • Shock: cardiogenic (R57.0), postprocedural (T81.1-), NOS (R57.9), complicating or following abortion or ectopic or molar pregnancy (O00-O07, O08.3), complicating or following labor and delivery (O75.1)
  • Stokes-Adams attack (I45.9)
  • Syncope: carotid sinus (G90.01), heat (T67.1), psychogenic (F48.8)
  • Unconsciousness NOS (R40.2-).

Documentation: Your cardiologist won’t need to change documentation habits just for ICD-10, but she should continue to be clear that the patient experienced syncope as opposed to one of the excluded diagnoses, such as unconsciousness or carotid sinus syncope.

Coder tips: The ICD-10 Official Guidelines are similar to the ICD-9 guidelines in relation to coding for signs and symptoms like syncope and collapse. “Codes that describe symptoms and signs, as opposed to diagnoses, are acceptable for reporting purposes when a related definitive diagnosis has not been established (confirmed) by the provider” (
