Use the code for a term followed by "NOS" when:
What is the difference between NEC and NOS in coding? NEC is used to indicate the diagnosis is specific; however, the coding system is not specific enough. NOS “Not otherwise specified” This abbreviation is the equivalent of unspecified, indicating the documentation does not provide enough information to assign a more specific code.
What does NOS Mean as a Medical Abbreviation? “NOS” simply means “Not Otherwise Specified.”. It’s an abbreviation that assists doctors pick from a standard list of codes that inform the diagnosis of your medical condition. Most of the times, a standard list has really specific codes that cover almost everything.
Not Otherwise Specified (NOS) and Not Elsewhere Classifiable (NEC) diagnosis - Medical Billing and Coding - Procedure code, ICD CODE. Only use “NOS” codes when the documentation is insufficient to code to a more specific code. This is synonymous with “Unspecified”. Example: A provider note indicates the patient has “otitis media.”
NOS “Not otherwise specified” This abbreviation is the equivalent of unspecified, indicating the documentation does not provide enough information to assign a more specific code.

What do the abbreviations NEC and NOS mean? NEC (not elsewhere classified) is used in the Alphabetic Index to indicate that there is no separate code for the condition. NOS (not otherwise specified) is the equivalent of "unspecified" and is used only in the Tabular List.
Claim submissions that contain procedure codes which are Not Elsewhere Classifiable (NEC), Not Otherwise Specified (NOS), or Unlisted should not be used when a more descriptive diagnosis or procedure code representing the service provided is available.
nos. plural of No. : a short form of "numbers": The same point applies to nos.
( ) Parentheses are used in both the Alphabetic Index and the Tabular List to enclose supplementary words that may be present or absent in the statement of a disease or procedure without affecting the code number to which it is assigned. The terms within parentheses are called nonessential modifiers.
Non-essential modifiers appear in parentheses following the terms they modify and do not affect the target code selection for a given condition, sign or symptom but are considered as alternatives to the expression of the term.
ICD-10-CM is a seven-character, alphanumeric code. Each code begins with a letter, and that letter is followed by two numbers. The first three characters of ICD-10-CM are the “category.” The category describes the general type of the injury or disease. The category is followed by a decimal point and the subcategory.
NEC means "not elsewhere coded"
The first is the alphabetic abbreviations “NEC” and “NOS.” NEC means “Not Elsewhere Classified” while NOS means “Not Otherwise Specified.” Simply put, NEC means the provider gave you a very detailed diagnosis, but the codes do not get that specific.
Public group.
The ICD-10-CM coding convention requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists there is a "Use Additional Code" note at the etiology code, and a "Code First" note at the manifestation code.
"NOS" is printed after topographic and morphologic terms that appear elsewhere in ICD-O with an additional modifying word or phrase. In the alphabetical index, "NOS" is listed, followed by the alphabetic listing of modifying words. Use the code for a term followed by "NOS" when:
Thus, "NOS" is printed in both the numerical lists and the alphabetic index to indicate to the coder and to the decoder that other modifiers of the term are listed elsewhere. In a few instances, "NOS" is also used to indicate that a particular term is used in a general sense.
What does NOS Mean as a Medical Abbreviation? “NOS” simply means “Not Otherwise Specified.”. It’s an abbreviation that assists doctors pick from a standard list of codes that inform the diagnosis of your medical condition. Most of the times, a standard list has really specific codes that cover almost everything.
“NOS” is used more than as soon as in this field, and may suggest “network os.” It might likewise mean “Nokia OS,” which is an os for Nokia cellular phone, or a kind of software called “NOS,” which is an operating system for the Control Data Corporation Cyber, a line of mainframe computer systems.
Most of the times, a standard list has really specific codes that cover almost everything. But your condition might be something that isn’t really specified because list, therefore your doctor chooses “NOS” instead. For example, you might have a stress and anxiety condition.
PDD-NOS. PDD-NOS is one of the 3 autism spectrum conditions. This one in particular is “prevalent developmental condition not otherwise specified,” which is also referred to as atypical autism. This is because the symptoms do not quite fit the other medical codes or descriptions for the condition. PD-NOS.
The abbreviation “NOS” also has a location in the world of science. Lots of people may acknowledge it has actually a shortened form of “Nitrous Oxide,” which is typically used in racing engines. It is likewise referred to as “nitrous” and has been used typically in pop culture movie that involves racing cars. It also means the lesser-known “nitric oxide synthase,” which is a class of enzymes. “NOS” can also be used as an acronym, such as for the “National Ocean Service” (part of the National Oceanic and Atmospheric Administration) and the “National Ornithological Society,” which is a society for bird-watchers.
1. New Old Stock. A really typically used phrase in the retail and auction service, this means products being marketed that were made a very long time back , and therefore aren’t really ‘brand-new.’.
It is necessary to keep in mind that “not otherwise defined” in a diagnosis or billing code is nothing to stress over, and merely indicates that the medical literature or billing codes don’t include your specific condition, or that your doctor hasn’t determined precisely what is going on yet.
Within ICD-9-CM, you may select codes defined as “Not Otherwise Specified” (NOS) when there isn’t enough documentation to select a more specific code. In other words, a deficiency in documentation prevents you from coding to a higher level of specificity.#N#NOS codes are never favored, and claims submitted with such diagnoses may be rejected for lack of medical necessity and/or specificity. When possible, you may wish to ask the documenting provider for additional information and/or to append the record, so that a more precise diagnosis may be selected.#N#Codes defined as “Not Elsewhere Classifiable” (NEC) may be selected when specific information is documented for the diagnosis, but there isn’t an existing ICD-9-CM code to report it. In this case, the ICD-9-CM manual—not the documentation—lacks additional specificity.
NOS codes are never favored, and claims submitted with such diagnoses may be rejected for lack of medical necessity and/or specificity . When possible, you may wish to ask the documenting provider for additional information and/or to append the record, so that a more precise diagnosis may be selected.
"S" (Sequela) - Complications that arise as a direct result of a condition.
The seventh character, "A", is an extension which, in this example, means "initial encounter". The 5th and 6th character sub-classification represent the most accurate level of specificity. All ICD-10 codes will begin with one of the following letters of the alphabet; the alpha characters are not case sensitive.
1. Codes are alphanumeric and may be up to 7 characters in length. 2. 1st character is always alpha; alpha characters may appear elsewhere in the code as well. (Alpha characters are NOT case sensitive.) 3. 2nd character is always numeric. 4. The remaining 5 digits may be any combination of alpha/numeric. 5.
In this instance, the letter “S” designates that the diagnosis relates to “Injuries, poisoning and certain other consequences of external causes related to single body regions.”
Codes in the ICD-10-CM code set can have anywhere from three to seven characters. The more characters there are, the more specific the diagnosis. The first character is always alpha (i.e., a letter), but characters two through seven can be either alpha or numeric. Let’s take a look at an example.
Although complete, M54.40 is unspecified, and wouldn't be the most accurate description of the patient's condition because it doesn't account for laterality. If the patient has a confirmed underlying diagnosis (i.e., the condition actually causing the back pain), then you should code for that first.
In some treatment scenarios, the bone is affected at the lower end (e.g., Osteoporosis, M80, M81). Even though the affected area may be located at the joint, the site of the condition is still considered the bone, not the joint.
Hi Tony, Yes, you can use Z codes as primary when there is no other option for a primary diagnosis. Per the official ICD-10-CM guidelines for coding and reporting, "Z codes may be used as either a first-listed (principal diagnosis code in the inpatient setting) or secondary code, depending on the circumstances of the encounter.".
