Organization, Consolidation and Presentation of Financial Statements [Abstract]
DESCRIPTION OF BUSINESS	DESCRIPTION OF BUSINESS Pacira BioSciences, Inc. and its subsidiaries (collectively, the “Company” or “Pacira”) deliver innovative, non-opioid pain therapies to transform the lives of patients. The Company’s long-acting, local analgesic, EXPAREL® (bupivacaine liposome injectable suspension), was commercially launched in the United States, or U.S., in April 2012 and approved in select European countries and the United Kingdom, or U.K., in November 2021. EXPAREL utilizes the Company’s proprietary multivesicular liposome, or pMVL, drug delivery technology that encapsulates drugs without altering their molecular structure and releases them over a desired period of time. EXPAREL is currently indicated to produce postsurgical local analgesia via infiltration in patients aged six years and older, and postsurgical regional analgesia in adults via (i) an interscalene brachial plexus block in adults; (ii) a sciatic nerve block in the popliteal fossa; or (iii) an adductor canal block in adults for postsurgical pain management (the safety and effectiveness of EXPAREL have not been established to produce postsurgical regional analgesia via other nerve blocks other than an interscalene brachial plexus nerve block, a sciatic nerve block in the popliteal fossa, and an adductor canal block). In November 2021, the Company acquired Flexion Therapeutics, Inc., or Flexion (the “Flexion Acquisition”), and added ZILRETTA® (triamcinolone acetonide extended-release injectable suspension) to its product portfolio. ZILRETTA is the first and only extended-release, intra-articular (meaning in the joint) injection indicated for the management of osteoarthritis, or OA, knee pain. The Company is also advancing two Phase 2 clinical programs—PCRX-201 (enekinragene inzadenovec), a novel, locally administered gene therapy for OA of the knee, and PCRX-2002, a complementary, long-acting formulation of the non-opioid analgesic ropivacaine for postsurgical pain control. PCRX-201 is the lead program from the Company’s proprietary high-capacity adenovirus, or HCAd, vector platform, which enables local administration of genetic medicines and has the potential to unlock gene therapy for large prevalent diseases affecting millions of people. In February 2025, the Company acquired the remaining 81 percent equity interest that it did not already own in GQ Bio Therapeutics GmbH, or GQ Bio (the “GQ Bio Acquisition”), a privately-held biopharmaceutical company, which included the novel HCAd platform, a preclinical portfolio of HCAd-based assets and research and development talent. Pacira is subject to risks common to companies in similar industries and stages, including, but not limited to, competition from larger companies and potential generic entrants, reliance on revenue from two commercialized products, reliance on a limited number of wholesalers, reliance on a limited number of manufacturing sites, new technological innovations, dependence on key personnel, reliance on third-party service providers and sole source suppliers, tariffs, protection of proprietary technology, compliance with government regulations and risks related to cybersecurity. The Company divested iovera®°, a handheld cryoanalgesia device that delivers immediate, long-acting, drug-free pain control using precise, controlled doses of cold temperature to a targeted nerve, to Zimmer, Inc., or Zimmer, a subsidiary of Zimmer Biomet Holdings, Inc. on July 31, 2026.
