HCPCS K0602: Replacement Battery for External Infusion Pump, 3V Silver Oxide - OpenPayer

Summary & Overview

HCPCS K0602: Replacement Battery for External Infusion Pump, 3V Silver Oxide

HCPCS Level II code K0602 covers a replacement silver oxide 3-volt battery for an external infusion pump owned by the patient. This supply-level code matters nationally because batteries are an essential maintenance item that enables continuous, safe delivery of infusion therapies in home and outpatient settings. Coverage and billing practices for pump supplies influence patient access, out-of-pocket costs, and provider billing workflows.

Key payers in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise description of the code, typical sites of service, and the service classification as a durable medical equipment accessory/supply replacement. The publication outlines common modifiers and administrative considerations where available, and summarizes payer coverage patterns and policy nuances that affect how K0602 is billed and reimbursed.

The analysis provides clinical context for why replacement batteries are billed separately from infusion pumps, operational implications for home infusion programs, and reference points for coding consistency. Data not available in the input is noted where applicable, and the piece is intended as a national-level reference for clinicians, billing staff, and policy analysts seeking clear information about HCPCS Level II code K0602.

Billing Code Overview

HCPCS Level II code K0602 describes a replacement battery for an external infusion pump owned by the patient, specified as a silver oxide, 3 volt cell, billed each. The service type is durable medical equipment accessory/supply replacement, supporting ongoing use of an external infusion pump by the patient. The typical site of service is home or other outpatient settings where the patient uses a personal infusion pump.

Clinical & Coding Specifications

Clinical Context

A patient with a home external infusion pump (e.g., PCA pump or ambulatory infusion pump for insulin, analgesia, or parenteral therapies) presents for routine device maintenance or reports pump failure due to a dead or failing power source. The patient owns the pump and requires a replacement silver oxide 3-volt battery (K0602) to restore pump function. Typical workflow: clinician or home health nurse verifies pump model and battery specification, confirms battery depletion, documents device ownership and clinical need, obtains and dispenses the replacement battery to the patient or caregiver, demonstrates correct installation and safe disposal of the spent battery, and documents the item and patient education in the medical record. Typical setting is outpatient clinic, durable medical equipment (DME) supplier location, home health visit, or inpatient discharge planning when the patient will take the pump home. Common patient conditions associated with external infusion pump use include chronic pain requiring patient-controlled analgesia, insulin pump therapy, chemotherapy/infusion therapy, or outpatient parenteral antimicrobial therapy where uninterrupted pump operation is required.

CPT Code	Description	Relationship to This Procedure
`99070`	Supplies and materials (except spectacles), provided by the physician over and above those usually included with the office visit or procedure, e.g., for sterile tray, vaccines; does not include DME.	Often billed when items or small supplies are provided in the office; some payers require `99070` for clinician-supplied batteries if HCPCS not accepted.
`99000`	Handling and/or conveyance of specimen for transfer from the office to a laboratory	Not directly related; included for workflow documentation only when device testing samples are sent.
`99406`	Smoking and tobacco use cessation counseling visit, intermediate, greater than 3 minutes up to 10 minutes	Not related clinically; no direct relationship—listed rarely in combined outpatient visits.
`97530`	Therapeutic activities, direct (one-on-one) patient contact by the provider (use of dynamic activities)	Can be used when a therapist provides device training that includes battery installation technique as part of ADL training.
`99000`	Supplies and materials - duplicate entry	Data not applicable; duplicate retained for payer systems that map supply billing differently.

Note: Specific CPT procedure codes are not typically required for the single-item supply K0602. Use of the HCPCS code K0602 is the primary billing element for the replacement battery. When procedural or clinical services occur (e.g., device reprogramming, training), relevant CPT codes for education, device interrogation, or therapy management should be appended per payer policy.
