Billing tips
Verify the exact monitoring duration before code selection - 93248 requires >7 days but <15 days; use 93247 for 7 days or less, 93270-93272 for 15+ days
Impact: Incorrect duration coding causes 30-40% of denials for this code family, resulting in claim rejections or recoupment during audits
Bill 93248 only once per monitoring period regardless of how many times the physician reviews the data; this is for the final comprehensive interpretation
Impact: Duplicate billing attempts result in automatic denials; one interpretation per monitoring session at $24.26
Do not bill 93248 with the technical/hookup codes (93245 setup, 93246 recording/transmission) on the same claim - split into separate date-specific claims
Impact: Bundling edits may deny the professional component; separate claims prevent $24.26 payment denial
Document the total number of days monitored, percentage of analyzable data, and specific cardiac events detected in the interpretation report
Impact: Insufficient documentation is cited in 25% of audits; complete reports protect the full $24.26 reimbursement
Link diagnosis codes that support medical necessity for extended monitoring (>7 days) rather than shorter-duration studies
Impact: Lack of medical necessity justification causes 15-20% payment denials; proper ICD-10 coding ensures payment
Submit claims with the date of service reflecting when the final interpretation was completed and signed, not the monitoring start date
Impact: Incorrect DOS causes processing delays and potential timely filing denials if monitoring started in a prior billing period
Common denials
Incorrect bundling with technical component codes 93245-93246 or global monitoring codes on the same claim
How to appeal: Resubmit on separate claims with appropriate dates of service; include documentation showing 93248 represents only the professional interpretation performed on a specific date, while technical components were provided on different dates; reference CPT guidelines separating professional and technical components
Medical necessity not established for extended monitoring duration (why >7 days was required versus shorter studies)
How to appeal: Submit clinical notes documenting prior non-diagnostic shorter-term monitoring, infrequent symptom patterns, or specific clinical indications requiring 7-15 day monitoring; include literature supporting extended monitoring for the specific diagnosis
Duplicate billing denial when multiple interpretations are submitted for the same monitoring period
How to appeal: If legitimately separate monitoring periods, provide device application/removal dates and documentation showing distinct monitoring sessions; if truly duplicate, withdraw second claim; preliminary reviews are included in the final interpretation
Insufficient or missing interpretation report documentation in medical record
How to appeal: Submit complete signed interpretation report including monitoring duration, data quality assessment, rhythm analysis, symptom correlation, and clinical recommendations; ensure report is dated and signed by the billing provider
Frequently asked questions
What is the difference between CPT 93248 and 93247?
CPT 93247 is for interpretation of extended ECG monitoring up to 7 days, while 93248 covers monitoring exceeding 7 days but less than 15 days. The monitoring duration determines which code to use - if the patient wore the monitor for 8, 10, or 14 days, use 93248. The 2025 Medicare rate for 93248 is $24.26.
How much does Medicare pay for CPT code 93248 in 2025?
The 2025 Medicare national average reimbursement for CPT 93248 is $24.26 for both facility and non-facility settings. This rate is based on 0.75 total RVUs (0.55 work RVU, 0.18 PE RVU, 0.02 MP RVU) multiplied by the 2025 conversion factor of 32.3465.
Can I bill 93248 with the monitoring hookup code on the same day?
No, 93248 should not be billed on the same claim with technical component codes 93245 (hookup) or 93246 (monitoring/transmission). The setup occurs on the application date, monitoring happens over 7-15 days, and 93248 is billed when the final interpretation is completed. Use separate claims with appropriate dates of service for each component.
What diagnosis codes support medical necessity for CPT 93248?
Common supporting diagnoses include R55 (syncope), R00.2 (palpitations), I49.9 (unspecified arrhythmia), I48.91 (atrial fibrillation), R42 (dizziness), and I47.1 (supraventricular tachycardia). The diagnosis should justify why extended monitoring beyond 7 days was medically necessary, often because shorter-term monitoring was non-diagnostic or symptoms are infrequent.
How many times can I bill 93248 for the same patient?
Bill 93248 only once per monitoring period, representing the final comprehensive interpretation of that 7-15 day monitoring session. If a patient undergoes separate monitoring periods (stopped and restarted monitoring), each distinct period can generate a separate 93248 charge. Multiple interim reviews during one monitoring period are included in the single interpretation fee.
What documentation is required to bill CPT 93248?
Required documentation includes a signed interpretation report stating the exact monitoring duration (>7 to <15 days), data quality assessment, comprehensive rhythm analysis, symptom-rhythm correlation, significant findings, and clinical recommendations. The report must be dated and signed by the interpreting physician and clearly indicate the monitoring period dates.
What is the RVU value for CPT code 93248?
CPT 93248 has a total RVU of 0.75 for 2025, consisting of 0.55 work RVU, 0.18 practice expense RVU (both facility and non-facility), and 0.02 malpractice RVU. When multiplied by the 2025 conversion factor of 32.3465, this yields the Medicare payment rate of $24.26.
