It binds antithrombin III to inhibit Factor Xa, and to a lesser degree thrombin. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That interrupts the coagulation cascade. Compared with unfractionated heparin, LMWHs give more predictable pharmacokinetics and usually need less laboratory monitoring.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The FDA-approved indications center on thromboembolic conditions. Before you link J1655 to a diagnosis, confirm the indication matches the drug&#8217;s approved labeling. Check the treating MAC&#8217;s local coverage determination (LCD) too, since coverage varies by payer.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Deep vein thrombosis (DVT):<\/strong> treatment of acute DVT in adults, with or without pulmonary embolism<\/li>\n\n\n\n<li><strong>Pulmonary embolism (PE):<\/strong> anticoagulation in confirmed PE where tinzaparin is clinically indicated<\/li>\n\n\n\n<li><strong>DVT prophylaxis:<\/strong> prevention in surgical patients, particularly orthopedic cases (confirm MAC coverage)<\/li>\n\n\n\n<li><strong>Extended anticoagulation:<\/strong> bridge therapy for patients who need sustained anticoagulation<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Understanding the clinical picture behind a J-code claim strengthens medical necessity documentation. The diagnosis on the claim has to explain why this drug was given, on this date, to this patient.<\/p>\n\n\n\n<h2 id=\"h-is-j1655-still-active\" class=\"wp-block-heading\">Is J1655 still active?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">No. J1655 has been removed from the active HCPCS Level II code set, and AAPC&#8217;s code database lists it under a deleted code path. CMS publishes HCPCS Level II updates each fall, with changes taking effect on January 1.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tinzaparin&#8217;s small US commercial footprint likely contributed to the removal.

A code deleted in 2020 may still be valid for services rendered before its deletion date. Audit your charge master every year so deleted J-codes never reach a claim.<\/p>\n            <\/div>\n        <\/div>\n    \n\n\n<h2 id=\"h-how-to-bill-j1655-coding-and-documentation-requirements\" class=\"wp-block-heading\">How to bill J1655: Coding and documentation requirements<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">When J1655 was active, billing followed the standard J-code framework for outpatient injectable drugs under Medicare Part B. Those requirements still matter. Billing teams audit historical claims and handle appeals for services rendered while the code was live.<\/p>\n\n\n\n<h3 id=\"h-unit-calculation\" class=\"wp-block-heading\">Unit calculation<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Each billed unit of J1655 equals 1,000 IU of tinzaparin sodium. A patient who received 18,000 IU in one administration generates 18 units on the claim. Over-reporting or under-reporting units is a common audit finding and a frequent trigger for recoupment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unit definitions differ from drug to drug, so read each descriptor before you calculate. <a href=\"https:\/\/pabau.com\/procedure-codes\/hcpcs-code-j1250\/\">J1250<\/a> is billed per 250 mg, not per IU.<\/p>\n\n\n\n<h3 id=\"h-national-drug-code-ndc-reporting\" class=\"wp-block-heading\">National Drug Code (NDC) reporting<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Medicare requires NDC information on most drug claims submitted under J-codes. The NDC must reflect the product actually administered, not a generic equivalent. Claims missing the N4 qualifier, the NDC number, or the quantity reject under most MAC edits.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Confirm the exact NDC format with your MAC&#8217;s billing and coding article for anticoagulant injectables. The same discipline applies to biologics such as <a href=\"https:\/\/pabau.com\/procedure-codes\/hcpcs-code-j0885\/\">J0885<\/a>. A complete record of administered NDCs supports <a href=\"https:\/\/pabau.com\/blog\/hipaa-compliance-for-medical-offices\/\">HIPAA-compliant documentation<\/a> and defends the claim at audit.<\/p>\n\n\n\n<h3 id=\"h-place-of-service-and-site-of-service-adjustments\" class=\"wp-block-heading\">Place of service and site-of-service adjustments<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Reimbursement rates for J-codes differ by site of service. Hospital outpatient departments bill under the Outpatient Prospective Payment System (OPPS). Physician office settings bill under the Medicare Physician Fee Schedule (MPFS).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the hospital outpatient setting, drug payments usually run through packaged payment or the OPPS packaging threshold. The separate ASP-based rate applies in office settings instead.<\/p>\n\n\n\n<h3 id=\"h-modifier-use\" class=\"wp-block-heading\">Modifier use<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">J-code drug claims need no special modifiers beyond the standard set. That includes GY for items Medicare does not cover, plus JW or JZ for drug wastage. Wastage reporting matters most with single-dose vials, as it does on <a href=\"https:\/\/pabau.com\/procedure-codes\/hcpcs-code-j1441\/\">J1441<\/a> claims. Confirm modifier requirements against the applicable MAC&#8217;s local coverage policies.<\/p>\n\n\n\n<h2 id=\"h-medicare-reimbursement-for-j1655\" class=\"wp-block-heading\">Medicare reimbursement for J1655<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Medicare paid J1655 under the <strong>Average Sales Price (ASP) methodology<\/strong>, the standard mechanism for separately payable Part B drugs. CMS updates ASP payment limits quarterly, in January, April, July, and October. Any historical rate lookup has to reference the correct quarter&#8217;s ASP file.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Under ASP methodology, Medicare pays ASP plus 6% for most Part B drugs in physician office settings. Hospital outpatient settings use OPPS rates, which may differ.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Because J1655 is deleted, current ASP files carry no payment rate for it. The <a href=\"https:\/\/www.cms.gov\/medicare\/physician-fee-schedule\/search\/overview\" target=\"_blank\" rel=\"nofollow noopener\">CMS Physician Fee Schedule lookup tool<\/a> confirms whether a successor code carries its own ASP rate.<\/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\">Reimbursement factor<\/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\">Detail<\/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\">Payment methodology<\/td>\n<td style=\"padding:12px 16px;color:#374151\">ASP + 6% (physician office); OPPS packaged rate (hospital outpatient)<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0;background:#F9FAFB\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">Update frequency<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Quarterly (January, April, July, October)<\/td>\n<\/tr>\n<tr style=\"border-bottom:1px solid #E8ECF0\">\n<td style=\"padding:12px 16px;font-weight:600;color:#121D36\">Current rate availability<\/td>\n<td style=\"padding:12px 16px;color:#374151\">Not available; code is deleted.

Pull the CMS HCPCS annual update file, then compare it against every active J-code you bill. Flag anything on the deleted list. Catching a deleted code before it reaches a claim always beats working the denial.<\/p>\n            <\/div>\n        <\/div>\n    \n\n\n<h2 id=\"h-how-pabau-keeps-injectable-drug-claims-clean\" class=\"wp-block-heading\">How Pabau keeps injectable drug claims clean<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In many practices, injectable drug detail lives in three places at once. The dose sits in the treatment note, the NDC on a vial label or spreadsheet, and the code in the charge master. When one drifts out of step, the claim denies.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Practice management software like Pabau keeps those three together. Pabau&#8217;s <a href=\"https:\/\/pabau.com\/features\/claims-management-software\/\">claims management software<\/a> pulls the administered product, the dose, and the code from the same clinical record. Your biller sees what the clinician charted, so the unit count on the claim matches the note.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That matters most in practices that inject every day. <a href=\"https:\/\/pabau.com\/industry\/iv-therapy-emr-software\/\">IV therapy practices<\/a> and <a href=\"https:\/\/pabau.com\/industry\/mens-health-clinic-software\/\">men&#8217;s health practices<\/a> bill drug codes on almost every visit. One mis-set unit definition then repeats across hundreds of claims.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Structured records also make the annual charge master review quick. You can see which codes you billed and when, then check that list against the current CMS update file before January&#8217;s changes bite.<\/p>\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                    Keep injectable drug claims accurate                <\/h3>\n\n                <p class=\"description\">\n                    Pabau links the administered product, dose, and NDC to the clinical record, so your billing team codes from what the clinician actually charted.

id=\"faq-question-1786626475474\"><h3 class=\"schema-faq-question\">What is HCPCS Code J1655?<\/h3> <p class=\"schema-faq-answer\">HCPCS Code J1655 is a Level II J-code that describes injection of tinzaparin sodium, 1,000 IU per billed unit. Tinzaparin sodium is a low molecular weight heparin (LMWH) anticoagulant used primarily for DVT and pulmonary embolism treatment. The code was used to bill Medicare and Medicaid for tinzaparin administered in outpatient settings. J1655 has since been deleted from the active HCPCS code set.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1786626475475\"><h3 class=\"schema-faq-question\">Is HCPCS Code J1655 still active or has it been deleted?<\/h3> <p class=\"schema-faq-answer\">J1655 has been deleted from the active HCPCS Level II code set. Submitting J1655 on a current claim will result in an automatic rejection. Check the CMS HCPCS annual update file for the relevant service year to confirm the deletion date. It will also show any crosswalk replacement code, which is typically J3490 when CMS assigned no specific successor.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1786626475476\"><h3 class=\"schema-faq-question\">What drug does HCPCS Code J1655 describe?<\/h3> <p class=\"schema-faq-answer\">J1655 describes tinzaparin sodium, a low molecular weight heparin anticoagulant marketed under the brand name Innohep. Each billed unit of J1655 represents 1,000 international units (IU) of tinzaparin administered by injection. Tinzaparin inhibits Factor Xa and thrombin via antithrombin III binding, interrupting the coagulation cascade in conditions such as DVT and pulmonary embolism.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1786626475477\"><h3 class=\"schema-faq-question\">Which anticoagulant J-codes replace J1655?<\/h3> <p class=\"schema-faq-answer\">Three active anticoagulant J-codes sit closest to J1655. They are J1650 for enoxaparin sodium per 10 mg, J1652 for fondaparinux sodium per 0.5 mg, and J1644 for unfractionated heparin per 1,000 units. If the prescriber switches the patient to enoxaparin, the claim moves to J1650 with units recalculated per 10 mg. Confirm the current status of all three codes annually via the CMS HCPCS overview.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1786626475478\"><h3 class=\"schema-faq-question\">How many units of J1655 should be billed per encounter?<\/h3> <p class=\"schema-faq-answer\">Each unit of J1655 equals 1,000 IU of tinzaparin sodium. Bill the number of units that corresponds to the total IU dose administered. For example, an 18,000 IU dose is billed as 18 units. Unit miscalculation is one of the most common denial triggers for LMWH J-code claims. Verify the administered dose against the billed unit count before submission.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1786626475479\"><h3 class=\"schema-faq-question\">Is NDC reporting required on a tinzaparin claim?<\/h3> <p class=\"schema-faq-answer\">Yes, Medicare requires NDC information on most Part B drug claims submitted under J-codes, including J1655. The NDC must be reported using the N4 qualifier, an 11-digit NDC number, and the correct unit of measure. Claims missing NDC data will reject under standard MAC edits. Confirm the exact requirements with your MAC&#8217;s billing and coding article for anticoagulant injectables, as they vary by payer.<\/p> <\/div> <\/div>\n","protected":false},"excerpt":{"rendered":"<p>HCPCS Code J1655 is a Level II J-code for injection of tinzaparin sodium, 1,000 IU per billed unit.
