Article - Billing and Coding: Single Chamber and Dual Chamber Permanent Cardiac Pacemakers – Coding and Billing (A54931)

CMS National Coverage PolicyN/AArticle TextAbstract:The National Coverage Determination (NCD) 20.8.3, Single Chamber and Dual Chamber Permanent Cardiac Pacemakers were revised with an effective date of August 13, 2013. The CMS A/B Medicare Administrative Contractors (MACs) have been instructed to implement the NCD at the local level. The following provides coding and billing instructions for the implementation of NCD 20.8.3. (CMS policy language is in italics.) The NCD Item/Service Description and Indications and Limitations are repeated here.Item/Service DescriptionA. GeneralPermanent cardiac pacemakers refer to a group of self-contained, battery operated, implanted devices that send electrical stimulation to the heart through one or more implanted leads. They are often classified by the number of chambers of the heart that the devices stimulate (pulse or depolarize). Single chamber pacemakers typically target either the right atrium or right ventricle. Dual chamber pacemakers stimulate both the right atrium and the right ventricle.The implantation procedure is typically performed under local anesthesia and requires only a brief hospitalization. A catheter is inserted into the chest and the pacemakers leads are threaded through the catheter to the appropriate chamber(s) of the heart. The surgeon then makes a small pocket in the pad of the flesh under the skin on the upper portion of the chest wall to hold the power source. The pocket is then closed with stitches.The Centers for Medicare & Medicaid Services (CMS) has determined that the evidence is sufficient to conclude that implanted permanent cardiac pacemakers, single chamber or dual chamber, are reasonable and necessary for the treatment of non-reversible symptomatic bradycardia due to sinus node dysfunction and second and/or third degree atrioventricular block. Symptoms of bradycardia are symptoms that can be directly attributable to a heart rate less than 60 beats per minute (for example: syncope, seizures, congestive heart failure, dizziness, or confusion).Indications and Limitations of CoverageB. Nationally Covered IndicationsThe following indications are covered for implanted permanent single chamber or dual chamber cardiac pacemakers:Documented non-reversible symptomatic bradycardia due to sinus node dysfunction, andDocumented non-reversible symptomatic bradycardia due to second degree and/or third degree atrioventricular block.C. Nationally Non-Covered IndicationsThe following indications are non-covered for implanted permanent single chamber or dual chamber cardiac pacemakers:Reversible causes of bradycardia such as electrolyte abnormalities, medications or drugs, and hypothermia,Asymptomatic first degree atrioventricular block,Asymptomatic sinus bradycardia,Asymptomatic sino-atrial block or asymptomatic sinus arrest,Ineffective atrial contractions (e.g., chronic atrial fibrillation or flutter, or giant left atrium) without symptomatic bradycardia,Asymptomatic second degree atrioventricular block of Mobitz Type I unless the QRS complexes are prolonged or electrophysiological studies have demonstrated that the block is at or beyond the level of the His Bundle (a component of the electrical conduction system of the heart),Syncope of undetermined cause,Bradycardia during sleep,Right bundle branch block with left axis deviation (and other forms of fascicular or bundle branch block) without syncope or other symptoms of intermittent atrioventricular block,Asymptomatic bradycardia in post-myocardial infarction patients about to initiate long-term beta-blocker drug therapy,Frequent or persistent supraventricular tachycardias, except where the pacemaker is specifically for the control of tachycardia, andA clinical condition in which pacing takes place only intermittently and briefly, and which is not associated with a reasonable likelihood that pacing needs will become prolonged.D. OtherMedicare Administrative Contractors will determine coverage under section 1862(a)(1)(A) of the Social Security Act for any other indications for the implantation and use of single chamber or dual chamber cardiac pacemakers that are not specifically addressed in this national coverage determination.(This NCD last reviewed August 2013.)Please note:The Decision Memo for Cardiac Pacemakers: Single-Chamber and Dual-Chamber Permanent Cardiac Pacemaker (CAG-00063R3) states:CMS initiated this current national coverage analysis to reconsider coverage indications for single chamber and dual chamber cardiac pacemakers. The scope of this reconsideration and this decision memorandum does not address biventricular pacemakers, pacemakers that stimulate more than two heart chambers, those devices used to treat tachyarrhythmias and cardiac dyssynchrony, cardiac resynchronization therapy, cardiac pacemaker evaluation services, or self-contained pacemaker monitors.Medicare Administrative Contractors will determine coverage under section 1862(a)(1)(A) of the Social Security Act for any other indications for the implantation and use of single chamber or dual chamber cardiac pacemakers that are not specifically addressed in this national coverage determination.The coding and billing guidelines only apply to those CPT codes for the initial insertion of cardiac pacemakers:33206 Insertion of new or replacement of permanent pacemaker with transvenous electrode(s); atrial33207 ventricular33208 atrial and ventricularThe NCD does not address replacement of pacemaker generators. CPT codes 33227, 33228 and 33229 or 33233 are therefore not addressed in this coding article.CMS NCD Covered Conditions and Diagnosis Codes  Group IClinical Conditions:Documented non-reversible symptomatic bradycardia due to sinus node dysfunctionDocumented non-reversible symptomatic bradycardia due to second degree and/or third degree atrioventricular blockDiagnosis Codes (ICD-10-CM) (Attest with Modifier - KX):Atrioventricular (AV) block ( I44.2)Mobitz (type II) AV block (I44.1)Other second degree AV block (I44.1)Sinoatrial node dysfunction/Sick sinus syndrome (I49.5)Congenital heart block (Q24.6)Contractor (Additional) Diagnosis Codes (ICD-10-CM) Allowed by the NCD  Group II (Attest with Modifier - KX)Atrioventricular block, unspecified (Symptomatic) (I44.30)First-degree atrioventricular block (Symptomatic with PR interval more than 300 milliseconds) (I44.0)Left bundle branch block, other or unspecified (I44.7)Right bundle branch block, unspecified or other (I45.10 / I45.19)Bundle branch block, unspecified (I45.10 or I45.19)Right bundle branch block and left posterior fascicular block (I45.2)Right bundle branch block and left anterior fascicular block (I45.2)o Other bilateral bundle branch block (I45.2)o Bifascicular block (I45.2)o Trifascicular block (I45.3)Supraventricular tachycardias in which a pacemaker is specifically for control of the tachycardia (I47.10 / I47.19 / I47.9)Paroxysmal supraventricular tachycardia/supraventricular tachycardia (SVT that is reproducibly terminated by pacing when catheter ablation and/or drugs fail to control the arrhythmia or produce intolerable side effects) (I47.10 / I47.19 / I47.9)Atrial fibrillation/atrial fibrillation, persistent; unspecified atrial fibrillation (I48.11 / I48.19 / I48.91) with symptomatic bradycardia due to necessary medical therapyAtrial flutter/atrial flutter, typical/atypical/unspecified (I48.3 / I48.4 / I48.92) with symptomatic bradycardia due to necessary medical therapyHypersensitive carotid sinus syndrome and neurocardiogenic syncope (Syncope without clear, provocative events and with a hypersensitive cardioinhibitory response of 3 seconds or longer or for significantly symptomatic neurocardiogenic syncope associated with bradycardia documented spontaneously or at the time of tilt-table testing (G90.01)Note: In order to receive proper payment,providersmustuse the KX modifier when billing for a pacemaker when the appropriate diagnosis for doing the procedure is listed in Group I or Group II (e.g. pacemaker or generator replacement or atrioventricular(AV) ablation).It may be appropriate and reasonable to insert a pacemaker up to 7 days prior to an AV ablation to ensure proper functioning of the pacemaker prior to a medically necessary and reasonable cardiac ablation procedure.Other Conditions Not Addressed by the NCD or by the Contractor - Group III include but are not limited to the following (Attest with Modifier - SC when the medical record does not support the use of a covered diagnosis from Group I or Group II):Cardiac resynchronization therapyObstructive hypertrophic cardiomyopathyPacing in children, adolescents, and patients with congenital heart diseasePacemaker or generator replacementsSustained pause-dependent ventricular tachycardia, with or without QT prolongationModifier Usage:Modifier - KX (Requirements specified in the medical policy have been met) must be used as an attestation by the practitioner and/or provider of the service that documentation is on file verifying the patient has a symptomatic arrhythmia or a high potential for progression of the rhythm disturbance requiring a permanent pacemaker forGroups I and II.

Modifier  GA may also be used on assigned claims when a patient refuses to sign the ABN and the latter is properly witnessed. For claims submitted to the Part A MAC, occurrence code 32 and the date of the ABN are required.Modifier  GZ should be used when the provider wants to indicate that it is expected that Medicare will deny the specific services as not reasonable and necessary and the beneficiary was not asked to sign an ABN.Claims for pacemaker claims that do not meet the criteria for modifier  KX or  SC should have modifier  GA or  GZ appended depending on the ABN status and will be denied.
