There are many many different medical products and services. As of 2010, there were over 25,000 different codes in the ICD-10. The ICD-9 is a huge book filled with all of the medical orders that can be billed.
These codes are also getting updated pretty frequently, but in 2013, there was a huge addition to the new medical coding and billing codes, which updated it to the ICD-10. There are now six times as many codes as there were before.
With so many different medical orders, there would need to be an individual alpha-numeric code for each one – that's the best and easiest way to keep track of so many orders! These codes are known as HCPCS, which stands for "Healthcare Common Procedure Coding System Code".
With so many different codes, people who work for doctor's offices and insurance companies aren't expected to memorize all of them – they can always refer to the book if they need to. It's interesting to find out how our medical supplies are billed.
If you have a portable oxygen concentrator, there is a special code that corresponds with it, as well as the accessories that you need to use it. Portable oxygen concentrators are first billed to the insurance companies as a “rental”, at least for the first portion of the contract with your medical supplier and the insurance company.
The HCPS code for a portable oxygen concentrator rental, as of 2015, is E1392. This code was actually updated in January of 2006, but a new report goes out each year to show whether or not a code has changed, or any other bits of information that go along with it. This is to make sure there are no potentially expensive mistakes when it comes to billing for your medical supplies.
The HCPCS codes are broken up into categories, and portable oxygen concentrators fall into "Level II", which are categorized as “durable medical equipment”. These are supplies that are used outside of a doctors office or other clinical facility. Ambulance services are also codes that are billed under this category.
There is also a long description, which is just "Portable oxygen concentrator, rental", a shorter description that excludes the word "rental", as well as a detailed description: "Oxygen and oxygen equipment (price subject to floors and ceilings). Durable Medical Equipment, Prosthetic's, Orthopedics, Supplies And Surgical Dressings".
There is a lot more that goes along with just that one bit of code, and it's all necessary to properly identify and bill your oxygen therapy equipment. Luckily, this work is left up to your medical supplier, wherever you receive your medical care, and your insurance company.
