== ~~Coding instructions~~ ==

There are two main categories of fractures:

*[[#Fractures due to trauma or injury]] -- by definition these have a so-called '''external''' cause or mechanism of injury". This means that the fracture was due to something external to the patient, such as getting hit by a baseball bat, or hitting their head on the pavement after falling off a ladder.

~~Work in progress~~, ~~but clearly~~ there are ~~some things that would be coded separately~~ for a fracture, ~~so starting this article rather than re~~-~~stating it in each dx article~~.

*[[#Nontraumatic fractures]] -- for these the main cause is something ''internal'' to the patient, such as a metastatic tumor to bone that weakens it.

* [[~~Osteoporosis~~ with new pathologic fracture]]

**While in these cases the fracture might well happen after some relatively minor stress to that bone (e.g. trying to open a jar of pickles, or lifting a heavy book), these should be included in the nontraumatic fracture category unless that stress would have led to a fracture in the absence of whatever weakened the bone.

* [[~~Osteoporosis without~~ new pathologic fracture]]

* [[Bone, stress fracture]]

===Fractures due to trauma or injury===

* [[~~Bone~~, ~~pathologic~~ fracture NOS]]

*These codes for traumatic fractures include BOTH closed and open fractures --- i.e. for an open fracture there is no need to additionally code the soft tissue injury that overlies it and renders it "open"

* [[~~Bone or cartilage~~, ~~benign neoplasm~~]]

**If a fracture, particularly an open fracture, is or becomes infected, then also code the infection

* [[Bone, ~~disorder of bone continuity~~]]

*For fractures due to ''external causes'' i.e. trauma or injury, there are specific codes identifying the bone in question.

* [[Bone ~~cyst~~]]

**Some of these are specific for a single bone, e.g: '''[[Femur, fracture, injury/trauma]]'''

*[[~~Bone~~, ~~pathologic fracture due to neoplastic disease~~]]

**Others identify a group of related bones, e.g: '''[[Ankle or foot or toes, fracture, injury/trauma]]'''

**And some are for when you only know the general region, e.g: '''[[Upper limb (arm) bones, level not specified/NOS, fracture, injury/trauma]]'''

*'''''For all such fractures''''', you MUST also code the mechanism of traumatic injury.

**If the mechanism of trauma is unknown or not among those listed, use '''[[Mechanism of injury: other NOS]]'''

===Nontraumatic fractures===

Here there are fewer codes, and the only bones for which we have specific codes are femur/pelvis and vertebrae. Nontraumatic fractures fall into 4 main subcategories:

# Pathologic fractures due to neoplastic disease -- here a neoplasm involving bone is the factor that weakened the bone.

#*[[Femur or pelvis, pathologic fracture due to neoplastic disease]]

#*[[Vertebra, pathologic fracture due to neoplastic disease]]

#*[[Bone NOS, pathologic fracture due to neoplastic disease]]

# Pathologic fractures due to osteoporosis -- here osteoporosis is the factor that weakened the bone.

#*[[Femur or pelvis, osteoporosis with new pathologic fracture]]

#*[[Vertebra, osteoporosis with new pathologic fracture]]

#*[[Bone NOS, osteoporosis with new pathologic fracture]]

# Stress fractures -- note here we have just one code, no codes for specific bones (i.e. it's one-size-fits-all for this type of fracture). These are due to repetitive stress rather than a single big event.

#*[[Bone, stress fracture]]

# Nontraumatic fractures NOS -- these are for nontraumatic fractures that don't fit into the other categories listed immediately above.

#*[[Femur or pelvis, nontraumatic fracture NOS]]

#*[[Vertebra, nontraumatic fracture NOS]] -- this includes vertebral compression/wedge fractures not due to neoplasm or osteoporosis.

#*[[Bone NOS, nontraumatic fracture NOS]]
