Interrog dev eval icpms ip
CPT 93290 covers the in-person evaluation and interrogation of an implantable cardioverter-defibrillator (ICD) or pacing cardioverter-defibrillator (ICPMS) system in a hospital or clinic setting. The healthcare provider downloads and analyzes the device data to check heart rhythm recordings and device function.

Billing tips
Bill 93290 only for in-person interrogations; use remote monitoring codes (93295-93296) for remote interrogations to avoid denials
Impact: Prevents automatic denials and recoupment; 93295 pays $21.33 vs $50.46 for 93290, so correct code selection impacts revenue by 136%
Document the specific reason for the in-person interrogation (pre-op clearance, device alert, symptoms, admission protocol) to establish medical necessity
Impact: Reduces denial rate by 40-60% according to carrier audits; missing medical necessity is the #1 denial reason
Ensure the full interrogation report is in the medical record, including all device parameters, stored events, battery status, and lead impedances
Impact: Comprehensive documentation prevents downcoding and supports appeals; incomplete reports lead to 25-35% denial rate
Do not bill 93290 on the same day as remote monitoring transmission codes (93295-93296) for the same device
Impact: NCCI edits bundle these services; billing both results in automatic denial of the lower-paying code and potential audit flags
Verify the device type before coding; use 93289 for pacemakers without defibrillator function and 93290 for ICDs or combined pacing/defibrillator systems
Impact: Incorrect device coding causes denials and delays; 93289 and 93290 have identical reimbursement but different clinical criteria
Bill once per hospitalization unless separate medical necessity exists for repeat interrogation (new symptoms, device reprogramming, post-procedure check)
Impact: Medicare typically allows one interrogation per admission; additional interrogations without clear justification face 80%+ denial rates
