Query

What diagnosis code should be assigned for the condition Chronotropic incompetence?

On researching this condition it is defined as “Chronotropic incompetence refers to the inability of the heart to increase its rate commensurate with increased activity or demand of the patient.”

As there is no ICD-10-AM index entry we’ve chosen I49.8 Other specified cardiac arrhythmias in the meantime, but would like confirmation.

Response

Based on clinical advice chronotropic incompetence is usually due to sinus node dysfunction and the clinicians consulted have advised the most appropriate diagnosis code to assign is I49.5 Sick sinus syndrome.
Free text should be used to specify the condition.
