CODING GUIDELINES

Chapter 13: Musculoskeletal System and Connective tissue

20

Site and laterality

Most of the codes within chapter 13 have site and laterality designations.


The site refers to the BONE, JOINT, or MUSCLE involved. 


For some conditions in which more than one bone, joint, or muscle is usually involved (e.g., osteoarthritis), a code is available for “multiple sites.”


If no multiple sites code is provided and if more than one bone, joint, or muscle is involved, separate codes should be used to indicate the different sites involved.

23

Bone Versus Joint

Bone may be affected at the upper and lower end


Portion of the bone affected may be at the joint, the site designation will be the BONE, not the joint

24

Acute Traumatic versus Chronic or Recurrent Musculoskeletal Conditions

Chapter 13 of ICD-10-CM contains bone, joint, or muscle conditions that are the result of a HEALED INJURY as well as RECURRENT CONDITIONS of these sites. 

25

Coding of Pathologic Fractures

Pathological fractures occur in bones that are weakened by disease.


These fractures are usually spontaneous but sometimes occur in connection with slight trauma (such as a minor fall) that ordinarily would not result in a fracture in normal, healthy bone. 

26

7th character extension (type of encounter)

  • A Initial encounter for fracture (ACTIVE TREATMENT)

  • D Subsequent encounter for fracture with routine healing 

  • G Subsequent encounter for fracture with delayedhealing 

  • K Subsequent encounter for fracture with nonunion

  • Subsequent encounter for fracture with malunion

  • S Sequela (late effect)

SEQUENCING

Sequencing of codes for pathological fractures depends on the circumstances of admission. A pathological fracture is designated as the principal diagnosis only when the patient is admitted solely for treatment of the pathological fracture. 


29

ASSIGNING

NEVER assign a code for both a traumatic fracture and a pathological fracture of the same bone; one or the other is assigned. 


NOTE: Fractures can be stress fractures, pathological fractures, or traumatic fractures

30

Pathological fracture due to OSTEOPOROSIS 

Osteoporosis is a systemic condition that affects all bones of the musculoskeletal system and leads to an increased risk of pathological fractures. In osteoporosis, the bones are thinner and weaker than normal.

31

Osteoporosis WITHOUT Pathologic Fracture (M81)

used for patients with osteoporosis who DO NOT currently have a pathologic fracture due to the osteoporosis, even if they have had a fracture in the past. For patients with a history of osteoporosis fractures, status code Z87.310, Personal history of (healed) osteoporosis fracture, should follow the code from M81.


Because osteoporosis is a systemic condition, site is NOT a component of the codes under category M81

32

Osteoporosis WITH current pathological fracture (M80)

is for patients who have a current pathologic fracture at the time of an encounter. The codes under M80 identify the site of the fracture. A code from category M80, not a traumatic fracture code, should be used for any patient with known osteoporosis who suffers a fracture, even if the patient had a minor fall or trauma, if that fall or trauma would not usually break a normal, healthy bone.

33

Pathological fracture due to NEOPLASM 

If the focus of treatment is the fracture, a code from subcategory M84.5, Pathological fracture in neoplastic disease, should be sequenced first, followed by the code for the neoplasm. 


If the focus of treatment is the neoplasmwith an associated pathological fracture, the neoplasm code should be sequenced first, followed by a code from M84.5 for the pathological fracture. 



34

OSTEOARTHRITIS

Osteoarthritis is the most common form of arthritis; it is also called polyarthritis, degenerative arthritis, and hypertrophic arthritis. 


Can be PRIMARY (unknown cause) or SECONDARY (caused by other disease or injury)


When the type of osteoarthritis is not specified, “primary” is the default.

35

BACK DISORDERS

Back pain described as lumbago or low back pain


The presence or absence of myelopathy is an important distinction to be made in assigning codes for certain back disorders.


Degeneration of the disc is not the same condition as displacement (herniation) of the disc, and each requires a different code.
