Final answer:
For a diagnosis of psychogenic paroxysmal tachycardia, the appropriate diagnostic codes are F45.9 for 'Somatoform disorder, unspecified' and I47.2 for 'Ventricular tachycardia', making option b) the correct choice.
Step-by-step explanation:
A patient diagnosed with psychogenic paroxysmal tachycardia indicates the presence of a cardiovascular psychophysiological disorder. Tachycardia, defined as a heart rate (HR) above 100 beats per minute (bpm) in a resting patient, can be caused by various factors, such as extreme stress, which may be triggered by the limbic system or autonomic nervous system disorders. Treatment for tachycardia varies depending on the underlying cause and can range from medications to implantable cardioverter defibrillators or surgery. Diagnostic codes like F45.8 and I47.1 are used to specify certain conditions; F45.8 refers to 'Other somatoform disorders,' while I47.1 denotes 'Paroxysmal ventricular tachycardia.'
Correct coding for a diagnosis of psychogenic paroxysmal tachycardia would be F45.9, which denotes 'Somatoform disorder, unspecified,' along with I47.2 denoting 'Ventricular tachycardia.'
The suitable answer would therefore be option b) F45.9, I47.2.
