What syncope ICD codes can I use?
If you’re looking for syncope ICD codes, there are several! Some of these ICD codes are for specific types of syncope, while some don’t even have syncope in their name but can be used for syncope. Here are some that you can use:
- G90.01 - Carotid sinus syncope
This ICD-10 code is meant to be used on a patient confirmed to have carotid sinus syncope, which means they lost consciousness due to carotid sinus hypersensitivity.
- R05.4 - Cough syncope
This ICD-10 code is meant to be used on a patient confirmed to have cough syncope, which means they lost consciousness due to coughing. This is not accepted as a principal diagnosis because it results from coughs caused by something specific, like asthma.
- T67.1XXA - Heat syncope, initial encounter
This ICD-10 code is meant to be used on a patient confirmed to have heat syncope, meaning the patient lost consciousness due to the heat. It commonly happens when it’s too hot for the patient, and they stand for long periods without moving or suddenly stand up after sitting or lying down for too long. The initial encounter label means they are being given active treatment for it.
- T67.1XXD - Heat syncope, subsequent encounter
This is the same as Item 3, but this time, it has a subsequent encounter label, which means that the patient is in the recovery phase and is still being given active care for heat syncope.
- T67.1XXS - Heat syncope, sequela
This is the same as Item 3, but this time, it has a sequela label, which means the patient is dealing with the after-effects of heat syncope. Given the label, this ICD-10 code should be accompanied by two other ICD-10 codes, one of which should designate the sequela’s nature, while the other should describe the sequela (meaning its effects). In the context of this ICD-10 code, these problems were caused by the heat syncope.
- T75.81XA - Effects of abnormal gravitation [G] forces, initial encounter
This ICD-10 code is meant to be used on patients dealing with the effects of abnormal gravitation forces. If you’re wondering what syncope has to do with this, there is a type of syncope called Airline Syncope, which is the loss of consciousness while flying in an airplane. Cabin air pressure, immobility, air quality, standing up after being seated for too long, and the centrifugal force while flying are possible reasons for this. This ICD-10 code also has an initial encounter label.
- T75.81XD - Effects of abnormal gravitation [G] forces, subsequent encounter
This is the same as Item 6, but this time, there’s a subsequent encounter label.
- T75.81XS - Effects of abnormal gravitation [G] forces, sequela
This is the same as Item 6, but this time, there’s a sequela label.
