The official descriptor reads: \u00ab\u00a0Replacement battery for external infusion pump owned by patient, lithium, 4.5 volt, each.\u00a0\u00bb Every word after \u00ab\u00a0patient\u00a0\u00bb narrows the code, and the voltage narrows it most.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">External infusion pumps deliver medication continuously or at programmed intervals outside a clinical setting. When the battery fails, therapy stops until it is replaced. The drug itself is billed separately, on codes such as <a href=\"https:\/\/pabau.com\/procedure-codes\/hcpcs-code-j1250\/\">J1250<\/a>. The pump carries its own code too, such as <a href=\"https:\/\/pabau.com\/procedure-codes\/hcpcs-code-e0784\/\">E0784<\/a>. K0605 pays only for the battery.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Two conditions have to hold before the code applies. The patient must own the pump rather than rent it, and the battery must be lithium at 4.5 volts. Practices using <a href=\"https:\/\/pabau.com\/blog\/best-emr-for-iv-therapy\/\">infusion practice EMR software<\/a> can attach the manufacturer&rsquo;s pump specification to the patient record. That puts the voltage in front of the biller at every reorder.<\/p>\n\n\n\n<h2 id=\"h-k0605-is-not-a-catch-all-code\" class=\"wp-block-heading\">K0605 is not a catch-all code<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The most common misreading of K0605 treats it as the generic option for any patient-owned pump battery. That reading fails on two points. Every code from K0601 through K0605 carries the phrase \u00ab\u00a0owned by patient\u00a0\u00bb, so ownership does not distinguish K0605 from its siblings. And K0605 names a chemistry and a voltage, which makes it the most specific code in the group rather than the loosest.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The family divides cleanly once you read the descriptors side by side. Chemistry comes first, then voltage.<\/p>\n\n\n\n<table style=\"width:100%;border-collapse:separate;border-spacing:0;border-radius:12px;overflow:hidden;font-size:15px;line-height:1.5;margin:1.5em 0 2em;box-shadow:0 2px 12px rgba(0,0,0,0.08)\">\n<thead>\n<tr>\n<th style=\"background:#121D36;color:#fff;padding:14px 16px;text-align:left;font-weight:600;font-size:14px;letter-spacing:0.3px;border-bottom:2px solid #2BADD4\">HCPCS code<\/th>\n<th style=\"background:#121D36;color:#fff;padding:14px 16px;text-align:left;font-weight:600;font-size:14px;letter-spacing:0.3px;border-bottom:2px solid #2BADD4\">Official descriptor<\/th>\n<th style=\"background:#121D36;color:#fff;padding:14px 16px;text-align:left;font-weight:600;font-size:14px;letter-spacing:0.3px;border-bottom:2px solid #2BADD4\">Chemistry and voltage<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">K0601<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Replacement battery for external infusion pump owned by patient, silver oxide, 1.5 volt, each<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Silver oxide, 1.5 volt<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">K0602<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Replacement battery for external infusion pump owned by patient, silver oxide, 3 volt, each<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Silver oxide, 3 volt<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">K0603<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Replacement battery for external infusion pump owned by patient, alkaline, 1.5 volt, each<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Alkaline, 1.5 volt<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">K0604<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Replacement battery for external infusion pump owned by patient, lithium, 3.6 volt, each<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Lithium, 3.6 volt<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">K0605<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Replacement battery for external infusion pump owned by patient, lithium, 4.5 volt, each<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Lithium, 4.5 volt<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">A4602<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Replacement battery for external infusion pump owned by patient, lithium, 1.5 volt, each<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Lithium, 1.5 volt<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">A9999<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Miscellaneous DME supply or accessory, not otherwise specified<\/td>\n<td style=\"padding:12px 16px;color:#374151\">The true catch-all, for any voltage the codes above do not describe<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n\n<p class=\"wp-block-paragraph\">Read that table in one direction only.

Codes A4602, K0604 and K0605 describe the lithium batteries commonly used with those pumps, and each code has an associated voltage. Lithium batteries at any other voltage must be billed using A9999.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Match the voltage first.<\/strong> Find the voltage in the pump manufacturer&rsquo;s documentation before you touch the claim. A 1.5 volt lithium cell is A4602, a 3.6 volt cell is K0604, and a 4.5 volt cell is K0605. Chemistry alone will not get you to the right code.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Use A9999 when nothing matches.<\/strong> A9999 is the miscellaneous DMEPOS supply code, and it is where a lithium battery goes when no descriptor covers its voltage. Because it is a not-otherwise-specified code, the DME MAC prices it by report. Include the battery manufacturer, model number, and suggested retail price in the claim narrative.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Bill one unit per battery.<\/strong> Every descriptor in this family ends with the word \u00ab\u00a0each\u00a0\u00bb. Two batteries dispensed on the same date are two units on the claim line, not one.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Do not bill a battery against a rented pump.<\/strong> Policy Article A52507 states that K0601 through K0605 are not separately payable when billed with a rented infusion pump. Patient ownership is a coding condition, not a formality on the setup form.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The PDAC, the Pricing, Data Analysis and Coding contractor, publishes a revised advisory on lithium battery coding that repeats these voltage assignments. Suppliers who cannot map a battery to a code can submit a coding verification request to the PDAC before billing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The same route settles other DMEPOS supply codes, including <a href=\"https:\/\/pabau.com\/procedure-codes\/hcpcs-code-a4290\/\">A4290<\/a>. Practices handling several DMEPOS supply codes can use <a href=\"https:\/\/pabau.com\/features\/automated-workflows-software\/\">automated billing workflows<\/a> to flag claims that need that verification first.<\/p>\n\n\n\n<h2 id=\"h-coverage-criteria-and-medical-necessity-for-hcpcs-code-k0605\" class=\"wp-block-heading\">Coverage criteria and medical necessity for HCPCS code K0605<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Medicare covers K0605 when the pump therapy itself is covered, the pump is patient-owned, and the documentation supports both. Coverage sits under the DMEPOS benefit and follows LCD L33794 together with Policy Article A52507.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The core coverage criteria are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The patient owns the external infusion pump rather than renting or leasing it<\/li>\n\n\n\n<li>The pump remains medically necessary for the patient&rsquo;s ongoing therapy<\/li>\n\n\n\n<li>The battery supplied is lithium and rated at 4.5 volts, as the K0605 descriptor requires<\/li>\n\n\n\n<li>The pump manufacturer&rsquo;s documentation specifies that battery for the model on file<\/li>\n\n\n\n<li>The prescribing physician has an active order on file supporting continued infusion therapy<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">When any of these is unmet or undocumented, the claim is likely to deny. A battery that meets every clinical test but runs at 3.6 volts is still the wrong code. It will be denied rather than paid at the K0604 rate.<\/p>\n\n\n\n<h3 id=\"h-documentation-requirements-for-k0605-claims\" class=\"wp-block-heading\">Documentation requirements for K0605 claims<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Incomplete documentation is the fastest path to denial. This checklist reflects the DME MAC requirements that apply to K0605 claims.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Physician or prescriber order:<\/strong> A written order from the treating physician covering continued infusion therapy and the replacement battery supply<\/li>\n\n\n\n<li><strong>Pump model documentation:<\/strong> Records confirming the manufacturer and model number of the pump the patient owns<\/li>\n\n\n\n<li><strong>Battery specification:<\/strong> The manufacturer&rsquo;s stated chemistry and voltage for that model, showing lithium at 4.5 volts<\/li>\n\n\n\n<li><strong>Proof of patient ownership:<\/strong> Documentation confirming the pump is owned, not rented, on the date of service<\/li>\n\n\n\n<li><strong>Medical necessity notes:<\/strong> Clinical records showing the therapy is ongoing and the pump is still in use<\/li>\n\n\n\n<li><strong>PDAC verification when needed:<\/strong> A coding verification response for any battery the published descriptors do not clearly cover<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Practices managing several infusion patients benefit from <a href=\"https:\/\/pabau.com\/blog\/medical-forms-at-your-healthcare-practice\/\">clinical documentation standards<\/a> that systematize these checks rather than relying on biller memory.

Verify the status for the current program cycle.<\/li>\n\n\n\n<li><strong>Units matter:<\/strong> Because the code is billed per battery, an allowable of a few dollars still multiplies across a year of reorders.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Annual fee schedule updates are easy to miss in a busy billing week. <a href=\"https:\/\/pabau.com\/blog\/practice-management-software\/\">Practice management platforms<\/a> can flag the date each year, which keeps suppliers off a stale allowable.<\/p>\n\n\n\n<h2 id=\"h-dmepos-jurisdiction-and-k0605-claim-submission\" class=\"wp-block-heading\">DMEPOS jurisdiction and K0605 claim submission<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Four DME MACs process DMEPOS claims across the country, each assigned to a geographic jurisdiction.

What can change is the local guidance, the appeal routing, and the portal a biller works in.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Suppliers serving several states should confirm the jurisdiction for each patient&rsquo;s home state before submitting. Consistent <a href=\"https:\/\/pabau.com\/blog\/hipaa-compliance-for-medical-offices\/\">HIPAA-compliant documentation<\/a> across every service location keeps each record to the same standard.<\/p>\n\n\n\n<h2 id=\"h-common-k0605-billing-errors-and-how-to-avoid-them\" class=\"wp-block-heading\">Common K0605 billing errors and how to avoid them<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Five patterns account for most K0605 denials. The first is a coding decision and the other four are process failures.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Using K0605 as a fallback.<\/strong> K0605 is the 4.5 volt lithium code. Reaching for it whenever the chemistry looks like lithium will mis-code the 3.6 volt cells that belong on K0604. There is a fallback code in this family, but it is A9999. Confirm the voltage, then pick the code.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Prescriber order not on file.<\/strong> Medicare requires an order from the treating provider supporting the ongoing infusion therapy. If that order lapses between claim periods, the K0605 line has nothing to anchor it. An automated renewal reminder ahead of the expiry date prevents the lapse.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Pump ownership not confirmed.<\/strong> K0601 through K0605 are not separately payable alongside a rented pump. If the pump moved from rental to purchase, or the other way, the claim has to follow. Rented equipment codes such as <a href=\"https:\/\/pabau.com\/procedure-codes\/hcpcs-code-e0302\/\">E0302<\/a> turn on the same distinction.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Jurisdiction routing error.<\/strong> Sending K0605 claims to the wrong DME MAC delays payment, and it happens most often to suppliers who serve patients across jurisdiction lines. The patient&rsquo;s permanent address sets the jurisdiction, not the supplier&rsquo;s enrolled location. Check the beneficiary&rsquo;s state on every claim.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Competitive bidding status not checked.<\/strong> If K0605 sits inside an active competitive bidding program for the patient&rsquo;s address, billing the national fee schedule rate will underpay or deny. Check the status at the start of each program cycle.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.pabau.com\/cdn\/attachments\/pulse\/content-engine\/billing_codes\/hcpcs-code-k0605\/automated-communication-in-pabau.webp\" alt=\"Automated communication in Pabau\"\/><figcaption class=\"wp-element-caption\"><em>Automated messages in Pabau chase a lapsing prescriber order before the next battery reorder, so the K0605 claim keeps its supporting document.<\/em><\/figcaption><\/figure>\n\n\n\n<div style=\"height:35px;width:800px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n        <div id=\"pro_tip\">\n            <div class=\"img\">\n                <svg width=\"42\" height=\"42\" viewBox=\"0 0 42 42\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\">\n                    <path fill-rule=\"evenodd\" clip-rule=\"evenodd\"\n                        d=\"M12.6383 19.5238C12.6632 21.2071 12.8734 22.9926 12.0685 24.5523C11.0341 26.8917 8.45076 28.169 7.56292 30.5918C6.63082 33.1061 7.19505 36.185 9.31371 37.9786C10.929 39.5678 13.4183 39.9873 15.6061 39.5463C17.4592 39.073 19.1049 37.8388 19.9706 36.1608C20.781 34.7141 20.7866 32.9904 20.5293 31.3985C20.1006 29.3092 18.3775 27.8705 16.9807 26.362C14.8814 24.1005 14.6684 20.6854 15.595 17.8915C16.4331 15.4768 19.0026 14.2344 20.0425 11.9461C20.7202 10.6769 20.7506 9.20327 20.6068 7.81304C20.1864 5.40098 18.3139 3.23631 15.8716 2.56674C13.9742 2.03969 11.8224 2.30052 10.1739 3.37614C8.70522 4.34688 7.5878 5.86618 7.28356 7.58178C6.76081 9.82981 7.53525 12.2822 9.20307 13.9118C10.7658 15.4741 12.4806 17.2273 12.6383 19.5238Z\"\n                        fill=\"#2BADD4\" \/>\n                    <path fill-rule=\"evenodd\" clip-rule=\"evenodd\"\n                        d=\"M22.7048 19.8387C22.6822 22.3279 24.4507 24.6234 26.7493 25.4682C28.0531 25.961 29.4725 25.9183 30.7989 25.5487C32.0575 24.9955 33.301 24.2237 34.0069 23.0092C34.8384 21.5811 35.2982 19.8286 34.7832 18.2094C34.3611 16.2507 32.8739 14.6541 31.0275 13.9426C28.6736 12.9595 25.8073 13.7942 24.1719 15.7001C23.2022 16.8366 22.6143 18.3326 22.7048 19.8387Z\"\n                        fill=\"#2BADD4\" \/>\n                <\/svg>\n            <\/div>\n            <div class=\"text\">\n                <h3>Pro Tip<\/h3>\n                <p>Run a quarterly review of active infusion battery accounts. Check three fields on each one: pump model, the manufacturer&rsquo;s stated battery voltage, and the prescriber order expiry date. It takes a few minutes per account and clears most of the denial risk.<\/p>\n            <\/div>\n        <\/div>\n    \n\n\n<h2 id=\"h-how-pabau-keeps-k0605-claims-audit-ready\" class=\"wp-block-heading\">How Pabau keeps K0605 claims audit-ready<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A clean K0605 claim rests on four facts that usually live in four different places. The pump model sits in a clinical note. The battery voltage sits in a product record. The prescriber order sits in a document folder. Ownership sits in the original setup paperwork, often on paper.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Practice management software like Pabau puts all four on one patient record. Pump manufacturer, model, and battery voltage can be captured on a digital intake form at setup. Those details then carry into every reorder without being asked again. Prescriber orders store against the same record with their expiry date in view.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So the biller checks one screen before submitting rather than chasing four. Pabau&rsquo;s claims management software then tracks authorization status and submission history against that same record. A denial is easy to trace back to the document behind it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Infusion-led practices can pair that with <a href=\"https:\/\/pabau.com\/industry\/iv-therapy-emr-software\/\">IV therapy EMR software<\/a>, which keeps the clinical and DMEPOS records in step. Diabetes and endocrine teams billing pump supplies get the same fit from <a href=\"https:\/\/pabau.com\/industry\/metabolic-health-emr\/\">metabolic health EMR<\/a>.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.pabau.com\/cdn\/attachments\/pulse\/content-engine\/billing_codes\/hcpcs-code-k0605\/comprehensive-emr-patient-record-management.webp\" alt=\"Comprehensive EMR &amp; patient record management\"\/><figcaption class=\"wp-element-caption\"><em>One patient record in Pabau holds the pump model, the battery voltage, the prescriber order, and the ownership paperwork a K0605 audit asks for.<\/em><\/figcaption><\/figure>\n\n\n\n<div style=\"height:35px;width:800px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n        <div id=\"book_a_demo\">\n            <div class=\"left-side\">\n                <div class=\"logo\">\n                    <img decoding=\"async\"\n                        src=\"https:\/\/pabau.com\/wp-content\/uploads\/2026\/01\/Logo.svg\"\n                        alt=\"Logo\"\n                        loading=\"lazy\"\n                    \/>\n                <\/div>\n\n                <h3 class=\"heading\">\n                    Manage DMEPOS billing without the paperwork pile                <\/h3>\n\n                <p class=\"description\">\n                    Pabau helps infusion and DME practices track authorizations, hold documentation checklists, and submit claims with the right supporting records attached.

Treat it as the most specific code in the K0601 to K0605 family rather than the loosest, and the common denial patterns stop appearing. When no descriptor matches the battery in hand, A9999 is where CMS points suppliers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The trade-off worth remembering is that the coding is the easy half. Keeping pump model, battery voltage, ownership status, and prescriber orders current across a patient panel is the part that takes a system.

class=\"schema-faq-question\">What does HCPCS code K0605 describe?<\/h3> <p class=\"schema-faq-answer\">HCPCS code K0605 describes a replacement battery for an external infusion pump owned by the patient, lithium, 4.5 volt, each. It is a HCPCS Level II K code billed as a DMEPOS supply. The chemistry and the voltage are both part of the definition.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1786603721962\"><h3 class=\"schema-faq-question\">Is K0605 a catch-all code for infusion pump batteries?<\/h3> <p class=\"schema-faq-answer\">No. K0605 is the most specific code in its family, because it names both lithium chemistry and 4.5 volts. The genuine catch-all is A9999, the miscellaneous DMEPOS supply code. CMS Policy Article A52507 directs suppliers to A9999 when a lithium battery&rsquo;s voltage matches none of the published descriptors.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1786603721963\"><h3 class=\"schema-faq-question\">How do you bill for a replacement battery for an external infusion pump?<\/h3> <p class=\"schema-faq-answer\">Start from the battery&rsquo;s chemistry and voltage, then pick the code. Silver oxide is K0601 at 1.5 volt and K0602 at 3 volt. Alkaline 1.5 volt is K0603. Lithium is A4602 at 1.5 volt, K0604 at 3.6 volt, and K0605 at 4.5 volt. Anything else goes on A9999.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1786603721964\"><h3 class=\"schema-faq-question\">What is the difference between K0605 and K0604?<\/h3> <p class=\"schema-faq-answer\">Voltage, and nothing else. K0604 covers a lithium 3.6 volt battery and K0605 covers a lithium 4.5 volt battery. Both descriptors include the words &lsquo;owned by patient&rsquo;, so ownership does not separate them. A lithium battery rated at 1.5 volt is A4602 instead.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1786603721965\"><h3 class=\"schema-faq-question\">Is K0605 covered under Medicare DMEPOS?<\/h3> <p class=\"schema-faq-answer\">Yes. K0605 is covered under the Medicare Part B DMEPOS benefit when the criteria in LCD L33794 and Policy Article A52507 are met. Coverage requires an active physician order for the therapy and documentation that the patient owns the pump. The battery must be lithium at 4.5 volts.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1786603721966\"><h3 class=\"schema-faq-question\">Can you bill K0605 alongside a rented infusion pump?<\/h3> <p class=\"schema-faq-answer\">No. Policy Article A52507 states that K0601 through K0605 are not separately payable when billed with a rented infusion pump. Every descriptor in the family says &lsquo;owned by patient&rsquo;. Confirm ownership status on the date of service before submitting.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1786603721967\"><h3 class=\"schema-faq-question\">What documentation is required for K0605?<\/h3> <p class=\"schema-faq-answer\">You need a prescriber order for the ongoing infusion therapy, records naming the pump manufacturer and model, and the manufacturer&rsquo;s stated battery chemistry and voltage. You also need proof the pump is patient-owned and clinical notes supporting continued therapy. Keep a PDAC coding verification response on file for any battery the descriptors do not clearly cover.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1786603721968\"><h3 class=\"schema-faq-question\">Which DME MAC processes K0605 claims?<\/h3> <p class=\"schema-faq-answer\">Routing follows the beneficiary&rsquo;s permanent address rather than the supplier&rsquo;s location. Noridian Healthcare Solutions administers jurisdictions A and D, while CGS Administrators handles jurisdictions B and C. Check the patient&rsquo;s home state before you submit.<\/p> <\/div> <\/div>\n\n","protected":false},"excerpt":{"rendered":"<p>HCPCS code K0605 bills a lithium 4.5 volt replacement battery for a patient-owned external infusion pump.
