With the invention of the engine lathe, which used an automatic feed to the cutting tool, basic lathes were used for precision metalworking. Even then, each lathe was unique, but the lathe operation was consistent.  Engine lathes helped usher in the Industrial revolution, which in turn introduced steam-powered lathes, capable of ever-greater rotation rates and the torque to rotate heavier parts. Lathes were now heavy duty machining tools. Like the milling machine, the lathe machine simplified the machining process as they became even more complete.The next great leap forward came in the second half of the twentieth century, with the advent of Computer Numerical Control (CNC). CNC-equipped lathes allowed operators to program a set of instructions for each machine tool. This allowed the exact duplication of those instructions, which meant parts that were increasingly accurate, and reduced the number of operators necessary to keep each machining tool running simultaneously. Today’s innovation provides increasingly precise CNC programming, with ever-growing numbers of axes.

Lathes, in some form, have been around since the Egyptians. Think of the resemblance to the pottery wheel; thrown pottery has been around for thousands of years, so it makes sense that lathes, which follow a similar principle but instead use a workpiece moving against a stationary cutting tool, would come along afterwards.

On the industrial side, big lathes produce countless numbers of parts: driveshafts on cars, legs for tables, etc. Heavy-duty, large-scale lathe tools can be used to turn a giant metal cone or disc, while small-scale machines can cut out a metal chess piece.

Lathes on an industrial scale can be quite large, but a toolroom lathe tends to be a somewhat smaller machine tool. A metal lathe is the mainstay of many small machine shops or tool-and-die companies, due to its versatility. Beyond the machine shop, many other craftsmen and hobbyists find a lathe indispensable. You can use a lathe to create parts for an old car:

In this case, the clay is the workpiece. The wheel is a rudimentary lathe, turning the workpiece at a set speed, and keeping it in one place. The head and cutting bits, in the example above, are the workman’s hands. They are the moving part – moving along the length of the workpiece (the “y” axis), and in and out towards the center of the workpiece (the “x” axis).

A skilled craftsman can turn a lump of metal into a cup, a lampstand, or even a chess piece with a lathe machine. There’s a huge variety of potential applications, and the ability to freehand the cutting and carving stages means that each piece still retains the unique touch of the craftsman.

In order for CMS to change billing and claims processing systems to accommodate the coverage conditions within the NCD, we instruct contractors and system maintainers to modify the claims processing systems at the national or local level through CR Transmittals. CRs are not policy, rather CRs are used to relay instructions regarding the edits of the various claims processing systems in very descriptive, technical language usually employing the codes or code combinations likely to be encountered with claims subject to the policy in question. As clinical or administrative codes change or system or policy requirements dictate, CR instructions are updated to ensure the systems are applying the most appropriate claims processing instructions applicable to the policy.

Lathes obviously work differently, utilizing a stationary cutting tool to trim the metal spinning around. Each lathe is a machine tool designed for heavy duty work, but modern lathes are designed for precision cutting and simplistic machining operation.

Nearly everything! But today’s uses tend to fall in the categories of “industrial” and “artisan” machine tools. Industrial uses cover everything from a locally-owned machine shop making replacement parts for old cars, to state-owned enterprises producing heavy machinery. On the other end of the spectrum, craftsmen are using lathes to produce unique and breathtaking pieces in wood, metal, glass, epoxy, and nearly every other material imaginable.

Today each industrial metalworking lathe is fully automated, with heads that can hold multiple bits. This means that the same lathe can perform numerous processes – rough bits for grinding out material, finer ones for refining parts, even bits for sanding and polishing. With a CNC lathe, a trained operator can program a metalworking lathe to bring a single workpiece from raw material to finished product with no human involvement at all once the program is initiated. A few individuals can oversee an entire production floor equipped with CNC lathes.

Most woodworking or machine shop tools are easily recognized. Drills, punches, and vises are fairly simple tools with a clear purpose. Other machines might be a bit more complicated and lathes, particularly high-end ones, fall into this category.At its heart, a lathe is a simplistic device, designed to hold a section of material as a turning tool carves, cuts or shapes it. This is called the workpiece. Unlike a simple vise, a lathe not only holds a workpiece, but also rotates it. This allows another part of the machine, the head, to move along the workpiece, holding various cutting tools  to shape the workpiece.

Articles which directly support an LCD are known as “LCD Reference Articles”. The referenced LCD may be cited in the Article Text field and may also be linked to in the Related Documents field. Examples may include but are not limited to Response to Comments and some Billing and Coding Articles. If you have a question about this kind of article, please contact the MAC listed within the Contractor Information section of the article. Articles identified as “Not an LCD Reference Article” are articles that do not directly support a Local Coverage Determination (LCD). They do not include a citation of an LCD. An example would include, but is not limited to, the Self-Administered Drug (SAD) Exclusion List Articles. If you have a question about this kind of article, please contact the MAC listed within the Contractor Information section of the article. There are different article types: Billing and Coding articles provide guidance for the related Local Coverage Determination (LCD) and assist providers in submitting correct claims for payment. Billing and Coding articles typically include CPT/HCPCS procedure codes, ICD-10-CM diagnosis codes, as well as Bill Type, Revenue, and CPT/HCPCS Modifier codes. The code lists in the article help explain which services (procedures) the related LCD applies to, the diagnosis codes for which the service is covered, or for which the service is not considered reasonable and necessary and therefore not covered. Response to Comment (RTC) articles list issues raised by external stakeholders during the Proposed LCD comment period. Self-Administered Drug (SAD) Exclusion List articles list the CPT/HCPCS codes that are excluded from coverage under this category. The Medicare program provides limited benefits for outpatient prescription drugs. The program covers drugs that are furnished "incident-to" a physician's service provided that the drugs are not "usually self-administered" by the patient. CMS has defined "not usually self-administered" according to how the Medicare population as a whole uses the drug, not how an individual patient or physician may choose to use a particular drug. For purpose of this exclusion, "the term 'usually' means more than 50 percent of the time for all Medicare beneficiaries who use the drug. Therefore, if a drug is self-administered by more than 50 percent of Medicare beneficiaries, the drug is excluded from coverage" and the MAC will make no payment for the drug. Draft articles are articles written in support of a Proposed LCD. A Draft article will eventually be replaced by a Billing and Coding article once the Proposed LCD is released to a final LCD.

The most basic lathes allowed craftsmen to free-hand the removal of material. Metal lathes and wood lathes technologically improved and eventually progressed into machine tools with integral heads. Each head mounted on cross-slides that ran the length of the lathe bed, over which the workpiece would rotate.

Title XVIII of the Social Security Act (SSA), §1862(a)(1)(A), states that no Medicare payment shall be made for items or services which "are not reasonable and necessary for the diagnosis or treatment of illness or injury or to improve the functioning of a malformed body member."
