M19 - Other and unspecified osteoarthritis

Version 2023
ICD-10:M19
Short Description:Other and unspecified osteoarthritis
Long Description:Other and unspecified osteoarthritis
Status: Not Valid for Submission
Version:ICD-10-CM 2023
Code Classification:
  • Diseases of the musculoskeletal system and connective tissue (M00–M99)
    • Osteoarthritis (M15-M19)
      • Other and unspecified osteoarthritis (M19)

M19 is a non-specific and non-billable ICD-10 code code, consider using a code with a higher level of specificity for a diagnosis of other and unspecified osteoarthritis. The code is not specific and is NOT valid for the year 2023 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Unspecified diagnosis codes like M19 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Specific Coding for Other and unspecified osteoarthritis

Non-specific codes like M19 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for other and unspecified osteoarthritis:

  • NON-BILLABLE CODE - M19.0 for Primary osteoarthritis of other joints
  • NON-BILLABLE CODE - M19.01 for Primary osteoarthritis, shoulder
  • NON-BILLABLE CODE - M19.02 for Primary osteoarthritis, elbow
  • NON-BILLABLE CODE - M19.03 for Primary osteoarthritis, wrist
  • NON-BILLABLE CODE - M19.04 for Primary osteoarthritis, hand
  • NON-BILLABLE CODE - M19.07 for Primary osteoarthritis ankle and foot
  • BILLABLE CODE - Use M19.09 for Primary osteoarthritis, other specified site
  • NON-BILLABLE CODE - M19.1 for Post-traumatic osteoarthritis of other joints
  • NON-BILLABLE CODE - M19.11 for Post-traumatic osteoarthritis, shoulder
  • NON-BILLABLE CODE - M19.12 for Post-traumatic osteoarthritis, elbow
  • NON-BILLABLE CODE - M19.13 for Post-traumatic osteoarthritis, wrist
  • NON-BILLABLE CODE - M19.14 for Post-traumatic osteoarthritis, hand
  • NON-BILLABLE CODE - M19.17 for Post-traumatic osteoarthritis, ankle and foot
  • BILLABLE CODE - Use M19.19 for Post-traumatic osteoarthritis, other specified site
  • NON-BILLABLE CODE - M19.2 for Secondary osteoarthritis of other joints
  • NON-BILLABLE CODE - M19.21 for Secondary osteoarthritis, shoulder
  • NON-BILLABLE CODE - M19.22 for Secondary osteoarthritis, elbow
  • NON-BILLABLE CODE - M19.23 for Secondary osteoarthritis, wrist
  • NON-BILLABLE CODE - M19.24 for Secondary osteoarthritis, hand
  • NON-BILLABLE CODE - M19.27 for Secondary osteoarthritis, ankle and foot
  • BILLABLE CODE - Use M19.29 for Secondary osteoarthritis, other specified site
  • NON-BILLABLE CODE - M19.9 for Osteoarthritis, unspecified site
  • BILLABLE CODE - Use M19.90 for Unspecified osteoarthritis, unspecified site
  • BILLABLE CODE - Use M19.91 for Primary osteoarthritis, unspecified site
  • BILLABLE CODE - Use M19.92 for Post-traumatic osteoarthritis, unspecified site
  • BILLABLE CODE - Use M19.93 for Secondary osteoarthritis, unspecified site

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to this diagnosis code:


Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Osteoarthritis

What is osteoarthritis?

Osteoarthritis, sometimes called OA, is a type of arthritis that only affects the joints, usually in the hands, knees, hips, neck, and lower back. It's the most common type of arthritis.

In a healthy joint, the ends of the bones are covered with a smooth, slippery tissue called cartilage. The cartilage pads the bones and helps them glide easily when you move the joint. With osteoarthritis, the cartilage breaks down and becomes rough. Sometimes, all the cartilage wears away and the bones rub together. Bumps of extra bone called bone spurs may grow in the joint area.

There is no cure for osteoarthritis. It usually gets worse slowly. But there's a lot you can do to manage the symptoms.

What are the symptoms of osteoarthritis?

Osteoarthritis affects people in different ways, and not everyone has pain. The most common symptoms are:

What causes osteoarthritis?

Researchers aren't sure what causes osteoarthritis. They think that it could be caused by a combination of factors in the body and the environment. Your chance of developing osteoarthritis increases with age. They also know that some people are more likely to develop it than others.

Who is more likely to develop osteoarthritis?

Things that make you more likely to develop osteoarthritis include:

How is osteoarthritis diagnosed?

There is no specific test for osteoarthritis. To find out if you have osteoarthritis, your provider:

What are the treatments for osteoarthritis?

The goal of treating osteoarthritis is to ease your pain, help you move better, and stop it from getting worse.

Treatment usually begins with:

You can buy some pain relievers and arthritis creams without a prescription. They can be helpful, but it's best to talk to your provider about using them. If they don't help enough, your provider may prescribe injections (shots) into the joint or prescription pain relievers.

Complementary therapies may help some people. Massage can increase blood flow and bring warmth to the area. Some research shows that acupuncture may help relieve osteoarthritis pain. Simple things like heat and ice can help, too.

If none of these treatments help enough, surgery may be an option. You and your provider can decide if it's right for you.
