Code Classification

  • Diseases of the musculoskeletal system and connective tissue
    (M00–M99)
    • Disorders of bone density and structure
      (M80-M85)
      • Disorder of continuity of bone
        (M84)

M84.639 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of pathological fracture in other disease, unspecified ulna and radius. The code is not specific and is NOT valid for the year 2024 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 M84.639 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 Applicable to Pathological fracture in other disease, unsp ulna and radius

Non-specific codes like M84.639 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for pathological fracture in other disease, unsp ulna and radius:

  • Use M84.639A for initial encounter for fracture - BILLABLE CODE

  • Use M84.639D for subsequent encounter for fracture with routine healing - BILLABLE CODE

  • Use M84.639G for subsequent encounter for fracture with delayed healing - BILLABLE CODE

  • Use M84.639K for subsequent encounter for fracture with nonunion - BILLABLE CODE

  • Use M84.639P for subsequent encounter for fracture with malunion - BILLABLE CODE

  • Use M84.639S for sequela - BILLABLE CODE

Patient Education


Arm Injuries and Disorders

Of the 206 bones in your body, three of them are in your arm: the humerus, radius, and ulna. Your arms are also made up of muscles, joints, tendons, and other connective tissue. Injuries to any of these parts of the arm can occur during sports, a fall, or an accident.

Types of arm injuries include :

  • Tendinitis and bursitis
  • Sprains
  • Dislocations
  • Fractures (broken bones)
  • Nerve problems
  • Osteoarthritis

You may also have problems or injure specific parts of your arm, such as your hand, wrist, elbow, or shoulder.

Fractures

A fracture is a break, usually in a bone. If the broken bone punctures the skin, it is called an open or compound fracture. Fractures commonly happen because of car accidents, falls, or sports injuries. Other causes are low bone density and osteoporosis, which cause weakening of the bones. Overuse can cause stress fractures, which are very small cracks in the bone.

Symptoms of a fracture are:

  • Intense pain
  • Deformity - the limb looks out of place
  • Swelling, bruising, or tenderness around the injury
  • Numbness and tingling
  • Problems moving a limb

You need to get medical care right away for any fracture. An x-ray can tell if your bone is broken. You may need to wear a cast or splint. Sometimes you need surgery to put in plates, pins or screws to keep the bone in place.
