ICD code Y74.2 – General hospital and personal-use implant failure

Key takeaways

Y74.2 covers implants, prosthetic materials and accessories from the general hospital and personal-use device class. Examples include devices in the FDA general hospital class, such as implantable patient-ID transponders.

It is a billable supplementary external cause code and can never be sequenced as the principal diagnosis.

Specialty implants take their own code: Y71.2 for cardiovascular devices, Y79.2 for orthopedic devices, Y77.2 for ophthalmic devices and Y72.2 for ENT devices.

Codes in Y70-Y82 need a documented device breakdown or malfunction. A complication with an intact, working device goes to Y83-Y84 instead.

Claims are most often denied because of incorrect sequencing as a primary diagnosis or a missing paired condition code.

Pabau’s claims management software supports electronic claim submission through the Claim.MD clearinghouse.

ICD-10 code Y74.2: Definition, descriptor, and billable status

ICD-10 code Y74.2 is assigned the official descriptor “Prosthetic and other implants, materials and accessory general hospital and personal-use devices associated with adverse incidents.”

It is a supplementary external cause code. You report it after the condition code when an implant from this device class breaks down or malfunctions.

Y74.2 is valid and billable under ICD-10-CM for fiscal year 2027, confirmed by the CDC/NCHS ICD-10-CM code lookup tool. The table below gives the quick-reference profile.

Clinical meaning: What devices does Y74.2 cover?

Y74.2 applies when an implant, prosthetic material or accessory from the general hospital and personal-use device class breaks down or malfunctions. The ICD-10-CM note for the Y70-Y82 block limits these codes to device breakdown or malfunction, whether during use, after implantation or in ongoing use.

General hospital and personal-use devices are the equipment used across every ward rather than in one specialty, so few implants belong to this class. The ICD-10-CM index does not name individual devices under Y74.2. The examples below come from the FDA’s general hospital and personal-use device panel (21 CFR Part 880), which shares the Y74 category’s name:

• Subcutaneous implanted intravascular infusion ports and their catheters
• Percutaneous, implanted, long-term intravascular catheters, such as tunneled central lines
• Implantable radiofrequency transponders used for patient identification
• Accessory materials and components supplied with these implants

Two conditions must both hold. The device is an implant, prosthetic material or accessory, and it belongs to the general hospital and personal-use class. Therapeutic nonsurgical and rehabilitative devices in that class, such as medical support stockings, go to Y74.1. Diagnostic and monitoring devices go to Y74.0.

Specialty implants use their own Y-code. The Y70-Y82 block is sorted by device specialty first. The fourth character then sets the device type, and .2 means prosthetic and other implants, materials and accessory devices in every specialty. So most implants are coded outside Y74:

• Y71.2: Cardiovascular implants, such as pacemakers, defibrillators, their leads and heart valves
• Y72.2: Ear, nose and throat implants, such as cochlear implants
• Y77.2: Ophthalmic implants, such as intraocular lenses and prosthetic eyes
• Y79.2: Orthopedic implants, such as hip and knee replacements and internal fixation devices
• Y81.2: General- and plastic-surgery implants
• Y70.2, Y73.2, Y75.2, Y76.2, Y78.2 and Y80.2: Anesthesiology, gastroenterology and urology, neurological, obstetric and gynecological, radiological and physical medicine implants
• Y82.8: Other medical devices that fit no specialty category

Reserve Y74.2 for implants in the general hospital and personal-use class that no specialty category fits.

Y74.2 in the ICD-10-CM code hierarchy

Y74.2 sits within the Y70-Y82 block of ICD-10-CM, which covers medical devices associated with adverse incidents. The CDC/NCHS tabular list publishes the block and its notes. Within that block, the Y74 category groups all general hospital and personal-use device codes together. The table below shows the full sibling structure of the Y74 family.

Use the AAPC Codify ICD-10-CM lookup to verify the current hierarchy and any Excludes notes before finalizing a code selection. Y74 has no .4 to .7 or .9 subcodes. A device complication without a breakdown or malfunction falls outside the block, under Y83-Y84 codes such as Y83.9.

Y74.2 vs other Y74 codes: How to choose the right code

Within Y74, the device type decides the subcode, not the nature of the adverse incident. Every Y74 code describes a device breakdown or malfunction, and only the type of device differs. The examples below follow the FDA’s general hospital and personal-use device list.

Key test: First, name the device’s specialty. A cardiovascular, orthopedic, ophthalmic or other specialty device takes its own category, so a pacemaker lead goes to Y71.2 and a hip component to Y79.2. Only a general hospital or personal-use device stays in Y74. Then pick the fourth character by device type, and use .2 for an implant, prosthetic material or accessory. The path below runs those checks in order.

Implanted ports and long-term intravascular catheters are the hard case. Their Y74.2 examples come from the FDA general hospital class, and ICD-10-CM does not list devices. Because these devices sit in the vascular system, some coders assign them to Y71.2 instead.

External cause coding rules for Y74.2

Y74.2 is an external cause code. Under ICD-10-CM Official Guidelines Section I.C.20, external cause codes are always supplementary. They describe the circumstances of an injury or adverse effect. They are reported after the condition or complication code that describes what happened to the patient. A grounding in medical billing fundamentals helps billers apply this sequencing rule consistently.

The sequencing rules for Y74.2 in practice:

1. First-listed code: The condition or complication caused by or associated with the device (for example, T82.514A, Breakdown (mechanical) of infusion catheter, initial encounter)
2. Secondary code: Y74.2 as the external cause identifying the device class responsible
3. Additional codes: Any other relevant condition codes, as applicable

Y74.2 cannot be the principal diagnosis under any circumstance. A claim filed with Y74.2 as the first-listed code will be rejected. The code also cannot stand alone on a claim. Payers need the paired condition code to see the full clinical picture.

ICD-10 Y74.2 documentation requirements

Medical record documentation must support every element of the Y74.2 code assignment. Payers and auditors look for three facts: the device, its failure, and the link between the two.

The medical record must contain all of the following to support Y74.2:

• Device class: Enough detail to tell a general hospital device from a cardiovascular, orthopedic or other specialty device
• Device identification: The name and type of the implant or prosthetic device, plus its manufacturer, model and serial number where available
• Nature of the adverse incident: A clear clinical description of the breakdown or malfunction itself, beyond the resulting diagnosis
• Causal link narrative: A physician or provider statement connecting the device to the patient’s presenting condition (for example, “port catheter fracture causing infusion failure”)
• Operative or procedure notes: Where the incident required surgery, the operative note must document the device and the findings at revision or removal
• Imaging or diagnostic reports: X-rays, CT scans, or other imaging confirming device position, failure mode, or structural compromise where applicable
• Timeline: Date of original device implantation or prosthetic fitting, and the onset of the adverse incident. This supports medical necessity and episode-of-care coding

Coders should query the treating physician when the adverse incident is documented but no explicit device linkage statement appears. Query as well when the record does not name the device type, because the specialty decides the Y-code.

Y74.2 payer requirements and claim submission

Medicare and Medicaid accept Y-series external cause codes as supplementary codes on inpatient and outpatient claims, but do not typically require them for reimbursement. Prior authorization is triggered by the primary procedure or condition codes, not by Y74.2 itself. Commercial payers vary. Some require external cause codes for adverse device events as part of medical necessity documentation, and others treat them as informational only.

Practical payer considerations for Y74.2 claims:

• Confirm whether the payer’s LCD or coverage policy for the primary condition code requires an associated external cause code before submitting
• For Medicare, consult the CMS ICD-10 codes page for any specific guidance on Y-code reporting in the relevant care setting
• Commercial payers may have specific edit rules linking implant complication T-codes to required external cause codes, so check the payer’s claims edit matrix
• Y74.2 does not add a separate payment. It supports the primary diagnosis’s medical necessity and may reduce audit exposure

A clearinghouse that runs claim edits before transmission catches many errors before they reach the payer. Our guide to the Claim.MD clearinghouse covers real-time claim editing and payer enrollment.

Common claim denial reasons for Y74.2

Claims carrying Y74.2 are denied for a predictable set of reasons. Each denial type has a specific resolution path.

Our denial codes reference and denial management workflow guide show how to track and resolve denials across code types.

Coding examples: When to use Y74.2

The following vignettes show correct code sequencing for Y74.2 and two cases where a different external cause code applies. Each example includes the clinical scenario, the correct primary code, and the external cause assignment.

Example 1: Implanted infusion port catheter breakdown

A patient receiving chemotherapy through a subcutaneous implanted port presents because the port no longer flushes. Imaging shows a fractured port catheter. The breakdown is the primary reason for the visit.

• Primary code: T82.514A, Breakdown (mechanical) of infusion catheter, initial encounter
• External cause code: Y74.2, Prosthetic and other implants, materials and accessory general hospital and personal-use devices associated with adverse incidents
• Device class note: ICD-10-CM does not say which Y-code an implanted port takes. Y74.2 follows the FDA general hospital class. Because the port sits in the vascular system, some coders report Y71.2, so apply facility policy or query the coding lead. Either way, make sure the record names the device
• Incorrect sequence: Leading with Y74.2 ahead of T82.514A results in a denial for an invalid principal diagnosis

Example 2: Pacemaker lead breakdown (Y71.2, not Y74.2)

A patient is admitted with symptomatic bradycardia traced to a fractured lead of a previously implanted cardiac pacemaker.

• Primary code: T82.110A, Breakdown (mechanical) of cardiac electrode, initial encounter
• External cause code: Y71.2, Prosthetic and other implants, materials and accessory cardiovascular devices associated with adverse incidents
• Common error: Reporting Y74.2 or Y74.1 for the lead. A pacemaker is a cardiovascular device, so it sits in Y71, and the implant subcode there is Y71.2

Example 3: Fixation device infection without malfunction (Y83.1, not Y74.2)

A patient develops a deep infection around a spinal internal fixation device placed six weeks earlier. The hardware is intact and working as intended. The infection is the primary reason for the hospital admission.

• Primary code: T84.63XA, Infection and inflammatory reaction due to internal fixation device of spine, initial encounter
• External cause code: Y83.1, the code for a surgical operation with implant of an artificial internal device as the cause of a later complication. No misadventure occurred during the procedure
• Why not a Y70-Y82 code: Those codes require a device breakdown or malfunction. If the fixation device had failed, Y79.2 would apply, because internal fixation devices are orthopedic

ICD-10 vs ICD-11: What changes for Y74.2?

ICD-11 restructures how medical device adverse incidents are classified. The concept covered by Y74.2 carries over to ICD-11 but is coded differently. Device type and failure mode (such as structural failure or dislodgement) are coded in Chapter 23.

For US billing purposes, this is informational only. ICD-10-CM 2027 remains the operative classification for all US clinical billing. CMS has not adopted ICD-11 for claim submission, and no transition date has been announced. Coders working in the US should continue using Y74.2 under ICD-10-CM and monitor CMS announcements for any future transition guidance.

How Pabau helps Y74.2 claims go out clean

A Y74.2 claim usually comes back over a detail. A missing condition code, a wrong seventh character or a thin device record sends it to rework, and each resubmission costs your billing team time.

Pabau, the practice management platform we build, includes claims software for practices. It validates each claim for missing or invalid details before it is sent to the Claim.MD clearinghouse. The integration supports electronic claim submission to thousands of US payers and real-time eligibility checks.

Treatment notes and invoices sit in the same patient record. When a payer queries the device link, your coder can check the documented device and failure without switching systems.

Reduce claim denials on device-related codes

Pabau’s claims management workflow validates claims for missing or invalid details before submission, so your billing team spends less time on rework.

Conclusion

Y74.2 is a narrow code, so reach for it last. Most implant failures belong to a specialty category, and a complication with an intact device belongs in Y83-Y84.

The judgment call is vascular access devices. Ports and long-term catheters follow the FDA general hospital class into Y74.2, but some coders report Y71.2. Set a facility rule, document it, and apply it the same way on every claim, so an audit finds one consistent answer.

Pabau supports electronic claim submission through the Claim.MD clearinghouse, with validation for missing or invalid details before each claim goes out. Book a demo to see how that cuts rework on device-complication claims.
