I47.11 vs R00.0
I47.11 (Inappropriate sinus tachycardia, so stated) compared with R00.0 (Tachycardia, unspecified), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.

No — do not report together. I47.11 carries an Excludes1 note covering R00.0: “tachycardia NOS (R00.0)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
No — do not report together. I47.11 carries an Excludes1 note covering R00.0: “sinoauricular tachycardia NOS (R00.0)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
No — do not report together. I47.11 carries an Excludes1 note covering R00.0: “sinus [sinusal] tachycardia NOS (R00.0)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
No — do not report together. R00.0 carries an Excludes1 note covering I47.11: “inappropriate sinus tachycardia, so stated (I47.11)”
