Can anyone give me advice on what documentation, other than the word paroxysmal, supports the assignment of PSVT or SVT? I need something to educate physicians with. Apparently, based on my research, these are the same condition and in ICD-10 will be the same code. But for now, in ICD-9 they are different codes. We get paid differently for each of these diagnoses in Risk Adjustment and I am trying to avoid an appearance of upcoding under ICD-9. I appreciate any insight you can provide. Thanks.
