Z86.79
ICD-10-CM
History of Supraventricular Tachycardia

Find comprehensive information on documenting and coding a history of supraventricular tachycardia SVT. This resource covers clinical criteria, ICD-10 codes I47.1 and I47, SNOMED CT concepts, differential diagnosis, and common medical terminology associated with a past diagnosis of SVT. Learn about appropriate documentation for paroxysmal supraventricular tachycardia, atrioventricular reentrant tachycardia AVRT, atrioventricular nodal reentrant tachycardia AVNRT, and Wolff-Parkinson-White syndrome WPW in medical records. Explore resources for healthcare professionals related to electrocardiogram ECG findings, patient history, and treatment considerations for prior episodes of SVT.

Documentation Best Practices

Documentation Checklist
  • Document onset, frequency, and duration of SVT episodes.
  • Describe symptoms associated with SVT (e.g., palpitations, dizziness).
  • Record ECG findings during SVT, including rate and rhythm.
  • Note any triggers or precipitating factors for SVT.
  • Document response to treatment and any recurrences.

Coding and Audit Risks

Common Risks
  • Unspecified SVT Type

    Coding SVT without specifying type (e.g., AVNRT, AVRT) leads to inaccurate DRG assignment and lost revenue.

  • Paroxysmal vs. Persistent

    Miscoding paroxysmal vs. persistent SVT impacts severity and can trigger audits or denials.

  • Atrial Fibrillation Confusion

    Incorrectly coding atrial fibrillation as SVT leads to coding errors and inaccurate quality reporting.

Mitigation Tips

Best Practices
  • Document onset, duration, frequency of SVT episodes for accurate ICD-10 coding (I47).
  • Specify SVT type (AVNRT, AVRT, atrial tachycardia) for proper CPT code selection.
  • Correlate ECG findings with symptoms to support SVT diagnosis and medical necessity.
  • Query physician for clarity if documentation lacks specifics for optimal reimbursement.
  • Ensure complete documentation of pre-existing conditions and medications for risk adjustment.

Clinical Decision Support

Checklist
  • Verify palpitations, rapid heart rate documented
  • Confirm ECG shows narrow QRS complex tachycardia
  • Check for abrupt onset and offset of tachycardia
  • Exclude other tachycardias like atrial fibrillation or flutter
  • Document symptoms, ECG findings, and differential diagnosis

Reimbursement and Quality Metrics

Impact Summary
  • Reimbursement: Accurate coding (I47.1) crucial for appropriate MS-DRG assignment and optimal payment. Coding variations impact case mix index (CMI), affecting hospital reimbursement.
  • Quality Metrics: SVT documentation impacts quality reporting tied to arrhythmia management, potentially affecting hospital performance scores and public reporting.
  • Coding Accuracy: Precise documentation of SVT type (AVNRT, AVRT, Atrial tachycardia) ensures correct ICD-10-CM code assignment (I47.1) and impacts payment.
  • Hospital Reporting: Correct SVT coding influences hospital data reporting for arrhythmia prevalence, treatment outcomes, resource utilization, impacting strategic planning.

Documentation Templates

Patient presents with a history of paroxysmal supraventricular tachycardia (PSVT).  Onset, duration, and frequency of SVT episodes are documented, including any triggers such as caffeine, stress, or exertion.  Symptoms experienced during tachycardia episodes are detailed, including palpitations, chest pain, shortness of breath, dizziness, lightheadedness, or syncope.  Electrocardiogram (ECG) findings during symptomatic episodes, if available, are described, noting the heart rate, rhythm, and presence of any pre-excitation features suggestive of Wolff-Parkinson-White syndrome.  Previous diagnostic testing for SVT, such as Holter monitoring, event monitoring, or electrophysiology studies, is reviewed.  Current management of SVT is outlined, including medications such as beta-blockers, calcium channel blockers, or antiarrhythmic drugs.  Prior interventions such as catheter ablation or cardioversion are also documented.  Patient's understanding of their condition, medication adherence, and response to treatment are assessed.  Differential diagnoses considered include atrial fibrillation, atrial flutter, and sinus tachycardia.  Patient education provided regarding SVT management, lifestyle modifications, and when to seek medical attention is documented.  Follow-up plan, including frequency of visits and any planned diagnostic testing, is clearly stated.  ICD-10 code I47.1, Paroxysmal supraventricular tachycardia, is confirmed as applicable.
