Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies The Company is involved, both as a plaintiff and a defendant, in various legal proceedings that arise in the ordinary course of business, including, without limitation, product liability and environmental matters in certain U.S. and international locations. Given the uncertain nature of litigation generally, the Company is not able, in all cases, to estimate the amount or range of loss that could result from an unfavorable outcome of litigation in which the Company is a party. In accordance with U.S. GAAP, the Company establishes accruals to the extent probable future losses are estimable (and in the case of environmental matters, without considering possible third-party recoveries). With respect to putative class action lawsuits in the United States and certain of the Canadian lawsuits described below, the Company is unable to estimate a range of reasonably possible losses for the following reasons: (i) all or certain of the proceedings are in early stages; (ii) the Company has not received and reviewed complete information regarding all or certain of the plaintiffs and their medical conditions; and/or (iii) there are significant factual issues to be resolved. In addition, there is uncertainty as to the likelihood of a class being certified or the ultimate size of any class. With respect to the civil investigative demands (“CIDs”) served by the Department of Justice which are discussed below, the Company is unable to estimate a range of reasonably possible losses for the following reasons: (i) all or certain of the proceedings are in early stages; and/or (ii) there are significant factual and legal issues to be resolved. Product Liability Matters As of March 31, 2023, the Company is defending approximately 33,285 product liability claims involving the Company’s line of hernia repair devices (collectively, the “Hernia Product Claims”). The majority of those claims are currently pending in a coordinated proceeding in Rhode Island State Court (“RI”) and in a federal multi-district litigation (“MDL”) established in the Southern District of Ohio, but claims are also pending in other state and/or federal court jurisdictions. In addition, those claims include multiple putative class actions in Canada. Generally, the Hernia Product Claims seek damages for personal injury allegedly resulting from use of the products. From time to time, the Company engages in resolution discussions with plaintiffs’ law firms regarding certain of the Hernia Product Claims, but the Company also intends to vigorously defend Hernia Product Claims that do not settle, including through litigation. The outcome in any one trial is not representative of potential outcomes of all cases or claims related to the Company’s product liability matters. •The first bellwether trial in the hernia MDL resulted in a complete defense verdict in favor of the Company in September 2021. •The second hernia MDL bellwether resulted in a $255 thousand verdict in April 2022. •The first bellwether trial in RI resulted in a $4.8 million verdict in August 2022, which the Company plans to appeal. Trials are currently scheduled in state and/or federal courts, including additional bellwether trials in the MDL in October 2023 and January 2024. The Company also expects additional trials of Hernia Product Claims to take place over the next 12 months in RI, including trials in September 2023 and October 2023. The Company also continues to be a defendant in certain other mass tort litigation. As of March 31, 2023, the Company is defending product liability claims involving the Company’s line of pelvic mesh products, the majority of which are pending in various federal court jurisdictions and in a coordinated proceeding in New Jersey Superior Court. Also, as of March 31, 2023, the Company is defending product liability claims involving the Company’s line of inferior vena cava (“IVC”) filter products. The majority of those claims are pending in various federal court jurisdictions after having been remanded from the MDL in the United States District Court for the District of Arizona. In most product liability litigations like those described above, plaintiffs allege a wide variety of claims, ranging from allegations of serious injury caused by the products to efforts to obtain compensation notwithstanding the absence of any injury. In many of these cases, the Company has not yet received and reviewed complete information regarding the plaintiffs and their medical conditions and, consequently, is unable to fully evaluate the claims. The Company expects that it will receive and review additional information regarding any remaining unsettled product liability matters. Other Legal Matters On February 27, 2020, a putative class action captioned Kabak v. Becton, Dickinson and Company, et al., Civ. No. 2:20-cv-02155 (SRC) (CLW), now captioned Industriens Pensionsforsikring v. Becton, Dickinson and Company, et al., was filed in the U.S. District Court for the District of New Jersey against the Company and certain of its officers. The complaint, which purports to be brought on behalf of all persons (other than defendants) who purchased or otherwise acquired the Company's common stock from November 5, 2019 through February 5, 2020, asserts claims for purported violations of Sections 10 and 20 of the Securities Exchange Act of 1934 (“Exchange Act”) and Securities and Exchange Commission (“SEC”) Rule 10b-5 promulgated thereunder, and seeks, among other things, damages and costs. The complaint alleges that defendants concealed certain material information regarding AlarisTM infusion pumps, allegedly rendering certain public statements about the Company’s business, operations and prospects false or misleading, thereby allegedly causing investors to purchase stock at an inflated price. After an initial without prejudice dismissal, the plaintiff filed amended pleadings, which the Company in turn moved to dismiss. Ultimately, the court permitted certain aspects of the case to proceed. An answer with affirmative defenses was thereafter filed on October 3, 2022. Discovery has commenced and plaintiff’s motion for class certification was filed on January 17, 2023. The Company believes that it has strong defenses to the allegations that were not dismissed and it intends to defend itself vigorously. On November 2, 2020, a putative shareholder derivative action captioned Jankowski v. Forlenza, et al., Civ. No. 2:20-cv-15474, was filed in the U.S. District Court for the District of New Jersey by a shareholder, derivatively on behalf of the Company, against certain of the Company’s directors and officers. The complaint asserts claims for breach of fiduciary duty, violations of sections 10(b), 14(a) and 21D of the Exchange Act, and insider trading. The complaint principally alleges that the Company made misleading statements regarding AlarisTM infusion pumps in a proxy statement and other SEC filings. A second derivative action was filed on January 24, 2021, and the two actions were consolidated. In March 2021, the Company received letters from two additional shareholders which, in general, mirrored the allegations in the derivative actions, and demanded, among other things, that the Board of Directors pursue claims against members of management for claimed breaches of fiduciary duties. Consistent with New Jersey law, the Board appointed a special committee to review the allegations and demands in the derivative actions and demand letters. Following an investigation, the special committee determined that no action was warranted, and rejected the shareholders’ demands, communicating its determination to counsel for the shareholders. On January 10, 2023, one of the two shareholders referenced above filed a separate derivative action that: (i) is generally consistent with the shareholder letter and the two prior actions; and (ii) purports to challenge the reasonableness of the special committee’s process and determination. The Company believes that is has strong defenses to these claims and intends to defend itself vigorously. In May 2017, the Company was sued by a competitor in the Northern District of New York, alleging antitrust violations related to certain aspects of the Company’s medical delivery solutions business in a case captioned AngioDynamics, Inc. v. C. R. Bard, Inc. et al., Civ. No. 1:17-CV-0598. Trial began on September 19, 2022, resulting in a complete defense verdict for the Company on October 6, 2022, from which AngioDynamics filed a notice of appeal. AngioDynamics withdrew its appeal and on February 17, 2023, the Second Circuit Court of Appeals entered an order dismissing the appeal, which preserved the trial victory and closed the case. In February 2021, the Company received a subpoena from the Enforcement Division of the SEC requesting information from the Company relating to, among other things, AlarisTM infusion pumps. The Company is cooperating with the SEC and responding to these requests. The Company cannot anticipate the timing, scope, outcome or possible impact of the investigation, financial or otherwise. In April 2019, the Department of Justice served the Company and CareFusion with CIDs seeking information regarding certain of CareFusion’s contracts with the Department of Veteran’s Affairs for certain products, including AlarisTM and PyxisTM devices, in connection with a civil investigation of possible violations of the False Claims Act, and the government recently expanded the investigation to include several additional contracts. The government has made several requests for documents and interviews or depositions of Company personnel. The Company is cooperating with the government and responding to these requests. In September 2021, the Company received a CID related to an inquiry initiated by the Northern District of Georgia in 2018. The requests concern sales and marketing practices with respect to certain aspects of the Company’s urology business. The government has made requests for documents and has interviewed employees. The inquiry is ongoing and the Company is cooperating with the government and responding to its requests. The Company and the government have agreed to mediation in an effort to resolve this dispute. In April 2023, the Department of Justice served the Company with a CID seeking information regarding the Company’s GenesisTM container products in connection with an investigation of possible violations of the False Claims Act. The government has made requests for documents and the Company is cooperating with the government and responding to its requests. In September 2021, the Company was served with a complaint from the New Mexico Attorney General, alleging violations of the state’s consumer protection laws in connection with the sales and marketing of its IVC filters. The Company’s motion to dismiss certain of the claims was granted on May 10, 2022 and discovery is proceeding as to the remaining claims. The Company intends to vigorously defend itself in the litigation. As the case is in its early stages, the Company cannot anticipate the timing, scope, outcome or possible impact at present. The Company was sued in state and federal courts in Georgia by plaintiffs who work or reside near Company facilities in Covington, GA, where ethylene oxide (“EtO”) sterilization activities take place. The federal cases have been dismissed and refiled in state court. The plaintiffs in the cases seek compensatory and punitive damages. Pursuant to Georgia statute, punitive damages in these cases are generally capped at $250,000 per claimant. The cases allege a variety of injuries, including but not limited to multiple types of cancer, allegedly attributable to exposure to EtO. The Company does not believe these cases are appropriate for class action treatment and they have not been filed as such. The Company currently has approximately 220 of such suits involving approximately 320 plaintiffs; approximately 45 of the cases also allege injury caused by exposure to a chemical of another defendant entirely unrelated to the Company. Three trial dates have been set in 2024. The Company has meritorious defenses and intends to defend itself vigorously and believes that future claims would generally face statute of limitations hurdles. The Company is also involved both as a plaintiff and a defendant in other legal proceedings and claims that arise in the ordinary course of business. The Company believes that it has meritorious defenses to these suits pending against the Company and is engaged in a vigorous defense of each of these matters. The Company cannot predict the outcome of these other legal matters discussed above, nor can it predict whether any outcome will have a material adverse effect on the Company’s consolidated results of operations and/or consolidated cash flows. Accordingly, the Company has made no provisions for these other legal matters in its consolidated results of operations. The Company is a potentially responsible party to a number of federal administrative proceedings in the United States brought under the Comprehensive Environment Response, Compensation and Liability Act, also known as “Superfund,” and similar state laws. The Company also is subject to administrative proceedings under environmental laws in jurisdictions outside the U.S. The affected sites are in varying stages of development. In some instances, the remedy has been completed, while in others, environmental studies are underway or commencing. For several sites, there are other potentially responsible parties that may be jointly or severally liable to pay all or part of cleanup costs. While it is not feasible to predict the outcome of these proceedings, based upon the Company’s experience, current information and applicable law, the Company does not expect these proceedings to have a material adverse effect on its consolidated results of operations and/or consolidated cash flows. Litigation Accruals The Company regularly monitors and evaluates the status of product liability and other legal matters, and may, from time-to-time, engage in settlement and mediation discussions taking into consideration developments in the matters and the risks and uncertainties surrounding litigation. These discussions could result in settlements of one or more of these claims at any time. The Company considers the following information when estimating its product liability accruals, including, but not limited to: the nature, quantity, and quality of unfiled and filed claims; the continued rate of claims being filed in certain product liability matters; the status of certain settlement discussions with plaintiffs’ counsel; the allegations and documentation supporting or refuting such allegations; publicly available information regarding similar medical device mass tort settlements; historical information regarding other product liability settlements involving the Company; and the stage of litigation. Because the information that is currently available regarding product liability matters is often limited, there is inherent uncertainty and volatility relating to the Company’s estimate of product liability. As additional information becomes available, the Company records adjustments to its product liability accruals as required. Accruals for the Company's product liability claims which are discussed above, as well as the related legal defense costs, amounted to approximately $1.9 billion and $2.1 billion on March 31, 2023 and September 30, 2022, respectively. These accruals, which are generally long-term in nature, are largely recorded within Deferred Income Taxes and Other Liabilities on the Company's condensed consolidated balance sheets. In view of the uncertainties discussed above, the Company could incur charges in excess of any currently established accruals and, to the extent available, liability insurance. In the opinion of management, any such future charges, individually or in the aggregate, could have a material adverse effect on the Company’s consolidated results of operations, financial condition, and/or consolidated cash flows.

On November 2, 2020, a putative shareholder derivative action captioned Jankowski v. Forlenza, et al., Civ.
