Does I45.10 require prior authorization?

No, I45.10 does not require prior authorization (high confidence). Covered without prior authorization.

`I45.10`, Unspecified right bundle-branch block

ICD-10-CM

No Prior Auth Required

Covered without prior authorization (high confidence)

Claims for Group I and Group II diagnoses must be attested with modifier KX to confirm documentation is on file verifying symptomatic arrhythmia or high risk of progression requiring a permanent pacemaker.
Group II contractor‑allowed diagnoses must be accompanied by the applicable ICD‑10‑CM diagnosis code(s) on the claim and KX attestation; contractor determination may be required for coverage.
Group III conditions (not addressed by the NCD) should be attested with modifier SC when applicable and are subject to separate contractor review and coverage policies.
Only CPT codes for initial insertion of permanent pacemakers (33206, 33207, 33208) apply to this NCD; claims should use these CPTs for initial implant procedures and not replacement CPTs addressed elsewhere.

Implantation of a single‑chamber or dual‑chamber permanent cardiac pacemaker is covered for documented non‑reversible symptomatic bradycardia due to sinus node dysfunction.
Implantation of a single‑chamber or dual‑chamber permanent cardiac pacemaker is covered for documented non‑reversible symptomatic bradycardia due to second‑degree and/or third‑degree atrioventricular (AV) block.
Symptoms attributable to bradycardia (heart rate <60 bpm) such as syncope, seizures, congestive heart failure, dizziness, or confusion qualify as symptomatic bradycardia for coverage purposes.
Additional contractor‑allowed diagnoses (Group II) are covered when the practitioner attests (use modifier KX) that documentation is on file verifying symptomatic arrhythmia or high potential for progression; examples include symptomatic/selected bundle branch/fascicular blocks, certain supraventricular tachycardias when pacing controls SVT, atrial fibrillation/flutter with symptomatic bradycardia due to therapy, and hypersensitive carotid sinus syndrome with cardioinhibitory response.
Implantation of a single-chamber or dual-chamber permanent cardiac pacemaker is covered for documented non-reversible symptomatic bradycardia due to sinus node dysfunction.
Implantation of a single-chamber or dual-chamber permanent cardiac pacemaker is covered for documented non-reversible symptomatic bradycardia due to second-degree and/or third-degree atrioventricular (AV) block.
