HCPCS Code C1895: Lead, cardioverter-defibrillator, endocardial dual coil

Key takeaways

HCPCS Code C1895 reports an implantable cardioverter-defibrillator lead placed endocardially with two defibrillation coils.

C1895 is billed under Medicare’s Outpatient Prospective Payment System, and coverage follows National Coverage Determination 20.4 for implantable automatic defibrillators.

A clean claim needs a matching ICD-10-CM diagnosis, bill type 13X with revenue code 278, and the device identifiers in the operative note.

C1896 is the code that gets confused with C1895, and it covers defibrillator leads that are neither endocardial single nor dual coil.

Practice management software like Pabau keeps device documentation on the patient record, so the professional claim goes out complete.

HCPCS Code C1895 reports an implantable cardioverter-defibrillator lead with two defibrillation coils, placed endocardially through a vein. Hospital outpatient departments submit it on a UB-04 claim alongside the implant procedure code. The code it gets confused with is C1896, which covers defibrillator leads that are neither endocardial single nor dual coil.

This reference covers the full descriptor, coverage under National Coverage Determination 20.4, and how OPPS pays for the device. It also sets out the ICD-10-CM pairings and the documentation a C1895 claim needs.

HCPCS Code C1895: definition and full descriptor

HCPCS Code C1895 is the Level II code assigned by the Centers for Medicare & Medicaid Services (CMS) to report a specific implantable cardiac device component. According to CMS, the official descriptor is:

The “C” prefix identifies this as an HCPCS Level II code maintained by CMS for hospital outpatient settings. Unlike CPT codes, which describe procedures, C-codes describe the devices used during them. They ride on the UB-04 claim alongside the procedure code.

Device type: what “endocardial dual coil” means

The endocardial dual coil lead is a transvenous lead placed inside the heart, and it carries two defibrillation coils. One coil typically sits in the right ventricle. The second sits in the superior vena cava or the right atrium.

That architecture lets the ICD generator deliver defibrillation energy across a broader cardiac volume than a single-coil lead can. The two designs are different devices, which is why they carry separate HCPCS codes.

Medicare coverage and eligibility criteria

Coverage for C1895 follows National Coverage Determination (NCD) 20.4, Implantable Automatic Defibrillators, which CMS implements through Billing and Coding Article A56340. Medicare covers ICD implantation, and the leads that go with it, when the documented clinical indications are met. Several of those indications turn on left ventricular ejection fraction, or LVEF.

Key Medicare coverage requirements under NCD 20.4 include:

• Prior cardiac arrest from ventricular fibrillation (VF), or from ventricular tachycardia (VT) with no transient or reversible cause
• Documented sustained VT, either spontaneous or induced during electrophysiology (EP) testing
• LVEF of 35% or less, 40 days or more after a myocardial infarction, with NYHA Class II or III heart failure
• LVEF of 35% or less with non-ischemic dilated cardiomyopathy and NYHA Class II or III heart failure, after three months of optimal medical therapy
• Familial or inherited conditions carrying a high risk of life-threatening VT, such as long QT syndrome or hypertrophic cardiomyopathy

Patients must not have irreversible brain damage, a life expectancy under one year, or an incessant VT or VF condition. Article A56340 sets out what the medical record has to carry before the C1895 claim is considered.

Covered ICD-10-CM diagnosis codes

Billing HCPCS Code C1895 requires an accompanying ICD-10-CM code that establishes medical necessity. The diagnosis code supports the claim but does not carry it on its own, which is why complete clinical documentation matters.

These are the diagnoses most often billed alongside C1895. Note that I47.2 is a parent code and cannot be submitted, so the claim needs a billable subcode such as I47.20 or I47.29. Article A56340 carries the full covered-code list, and CMS revises it every year.

HCPCS Code C1895 fee schedule and Medicare payment rates (2026)

C1895 is reimbursed under the Medicare OPPS, so payment follows an Ambulatory Payment Classification (APC) assignment rather than a fixed national fee. Those rates are updated annually through the CMS OPPS final rule, published each November for the following calendar year. Check the current OPPS Addendum B to confirm how the code is treated for the year you are billing.

OPPS pass-through status and APC assignment

Device pass-through status under OPPS runs for a limited period, typically two to three years. It applies while a new device is not yet reflected in OPPS cost data. During that window, Medicare pays the device separately from the procedure APC. Once the window closes, the device cost is packaged into the procedure APC.

Pass-through status is granted per device category, so each code needs its own check. Check the current Addendum B before you assume C1895 or another device code such as C1825 still holds it. Last year’s notes will not answer that.

Billing requirements: bill type and revenue codes

C1895 is billed only on a UB-04 institutional claim by hospital outpatient departments. Device C-codes sit on the institutional side of medical billing, so the claim form matters as much as the code itself. Electronic claim submission through the 837I is the standard for Medicare OPPS, and a CMS-1500 submission is rejected outright.

Billing teams should confirm revenue code requirements with their Medicare Administrative Contractor (MAC). Revenue code 278 is standard for implantable devices, though some MACs ask for more specificity. Capture the device manufacturer, model number, and lot number in the record before the claim goes out.

Documentation requirements for C1895 claims

Documentation is where most C1895 denials start. Medical billing compliance for device codes means the record has to prove two separate things: that the patient qualified, and which device went in.

Required documentation elements include:

• Documented indication: the clinical condition that meets NCD 20.4, with the LVEF measurement, NYHA class, and VT or VF history in the physician’s notes
• Device identification: the lead’s manufacturer, model number, and serial or lot number, taken from the device label and recorded in the procedure note
• Procedure note: a signed operative report naming the lead type, dual coil and endocardial, and its placement
• Cardiology evaluation: the EP study, Holter results, or echocardiographic findings that support the indication
• Prior authorization records: where a MAC or commercial payer requires one, the reference number from the prior authorization belongs on the claim
• Physician attestation: the implanting physician’s signature and credentials on every relevant document

One missing element is enough to trigger a medical necessity denial. The device model and lot number and the documented LVEF are the two that go missing most often. Build a pre-submission checklist into the billing workflow for every C1895 claim.

C1895 vs C1896 and related defibrillator lead codes

The most consequential coding decision on an ICD lead is choosing between C1895 and C1896. Both describe cardioverter-defibrillator leads, but not the same device. The wrong choice bills for a device the patient never received, which is a compliance problem rather than a simple denial.

The distinction sits in the lead design. C1895 is specific to endocardial leads, placed transvenously inside the heart, with two defibrillation coils. C1896 picks up the leads that miss that description, subcutaneous ICD leads included. The introducer sheath used to place the lead has its own device code, C1893.

Common billing errors and how to avoid them

Denial patterns for C1895 repeat often enough that a billing team can see them coming. Six account for most of the rejections.

• Wrong lead code selected: using C1895 for a subcutaneous or other non-endocardial lead, which belongs under C1896. Cross-reference the implant card against the descriptor before submission.
• Missing device identification: claims without the manufacturer, model, and lot number are routinely denied. Revenue code 278 lines for implantable devices need full device traceability.
• ICD-10-CM mismatch: a covered diagnosis has to appear on the claim and match the record. I47.20 submitted without documented sustained VT will fail a medical necessity review.
• Wrong claim form: C1895 is institutional and belongs on a UB-04. A CMS-1500 submission is rejected outright.
• Outdated APC rate used: OPPS rates change annually. A prior year’s Addendum B sets the wrong payment expectation and can hide a shifted APC assignment.
• Prior authorization not obtained: some MACs and many commercial payers require authorization for ICD implantation. A missing authorization number triggers an immediate denial.

Pairing a pre-submission audit with denial tracking is what stops the same error repeating. A denial management process shows which of these six a team keeps making, and the remark codes behind each rejection are listed under denial codes.

Code history and effective dates

C1895 has been active as a CMS Level II code for hospital outpatient device reporting, and it remains active for the 2026 billing year. C-codes are assigned and updated by CMS through the annual OPPS rulemaking cycle. Verify the current status and any descriptor revision through CMS’s HCPCS code release page, which publishes the Level II update each fall.

Mid-year HCPCS changes are rare for established C-codes. They happen when CMS issues a correction notice, or revises a descriptor because a new device category needs one.

For programmatic lookups, the NLM Clinical Tables HCPCS API gives free access to the current code set. That is the cheapest way to validate a device code at the point of entry rather than at the point of denial.

How Pabau keeps device documentation with the claim

C1895 itself belongs to the hospital, on the UB-04. The cardiology practice that performed the implant still bills its own professional claim. That claim leans on the same operative note, the same LVEF measurement, and the same implant card.

Practice management software like Pabau keeps those documents on the patient record instead of scattered across a shared drive. The note, the consent, the device photo, and the payer details sit in one file. When a payer asks for the implant detail 11 months later, nobody has to go hunting for it.

Claims then go out through the Claim.MD integration, our US clearinghouse connection, and each remittance posts back against the same record. Pabau’s claims management tools submit and track what the record already holds. A denial lands next to the patient and the code that caused it.

The same workflow carries over to any specialty that bills Medicare for documentation-heavy visits. A physical therapy practice tracking plan-of-care recertification and a regenerative medicine clinic billing device-heavy procedures both live or die by the same record-keeping.

Keep device documentation with the claim

Pabau stores the operative note, device details, and consent on the patient record, then submits the claim through Claim.MD and posts the remittance back. Fewer denials start from paperwork nobody can find.

Conclusion

The operative note decides whether a C1895 claim pays. If it names the lead as endocardial with two coils, and carries the model and lot number, the coding part is close to mechanical. If it doesn’t, no amount of appeal work will invent the detail after the fact.

The part worth remembering is that C1895’s payment treatment is not a fixed fact about the code. It moves with each annual final rule, so a January look at Addendum B costs less than a rebilling cycle in March.
