MDC 24

Objectives

Gain a practical understanding of principles governing Multiple

Significant Trauma under the MS-DRG system

Recognize clinical clues, signs and symptoms of specific disease entities subject to unrecognized opportunities for clinical clarification during the chart review process

Learn how to practically apply underlying principles of Multiple

Significant Trauma through use of case studies as part of the presentation

DEFINITION OF TRAUMA

Refers to "wound" body wound/shock produced by sudden physical injury from accident or violence>>>major trauma.

This can result in secondary complications; 
 shock/failure/death.

Treatment of the trauma patient often involves multiple 
management diagnostics and procedures

What Qualifies for MST

PDX from Trauma Diagnosis List

AND 2 additional body sites

_____________

OR

____________

PDX from 1 body site

& 1 additional body site

Trauma Diagnosis List

Less severe and do not qualify as a “body site”

Examples:

Closed or open skull fractures with no or unspecified LOC, or w/ concussion

Concussion w/ no LOC, unspecified, or LOC < 1 hr

Vertebral fracture, open or closed, without spinal cord injury

Rib fractures - closed, 6 or less, or unspecified

Rib fractures - open, 3 or less, or unspecified

Sternum, clavicle, or scapula - closed fracture

Trauma Diagnosis List, cont

Closed Fractures of upper or lower extremity

Dislocations, open or closed

(except open hip, knee, ankle, shoulder, elbow)

Sprains or strains

Open wounds

Traumatic amputation of thumb, fingers or toes (complete or partial)

Trauma Diagnosis List, cont

Injury to blood vessels

Superficial injuries

Contusions

Injury to nerves

Complications of trauma, secondary and recurrent hemorrhage

Posttraumatic wound infection NEC

Injury, other and unspecified

Body Site Categories

MST 1 Head

MST 2 Chest

MST 3 Abdomen

MST 4 Kidney – Adrenal

MST 5 Urinary – Pelvic

MST 6 Pelvis – Spine

MST 7 Upper Limb

MST 8 Lower Limb

Intercranial injury

Skull or multiple facial fractures, open or closed, w/cerebral lac intercranial hemorrhage

Cerebral laceration and contusion blood

Injury to carotid artery, jugular vein, or multi vessels of head/neck

MST 2Chest

Rib fractures: Closed, 7 or more

Open, 4 or more

Sternum, open fracture or open dislocation

Traumatic pneumothorax or hemothorax

Injury to heart and lung (heart and lung contusion)

Injuries to thoracic blood vessels, subclavian veins, superior vena cava, thoracic aorta

Complications of trauma, air or fat embolism

MST 3Abdomen

Injury with or without open wound to:

Stomach, Small intestine, colon, rectum, pancreas, bile duct and gall bladder, other GI sites

Injury to appendix w/o mention of open wound

Injury to Liver or spleen

Injury to other GI sites, without mention of open wound into cavity: ie traumatic insertion of NG tube

Injury to blood vessels of the abdomen and pelvis

MST 4Kidney

Injury to kidney

Injury to adrenal gland w/ or w/o mention of open wound

MST 5Urinary

Injury to pelvic organs (bladder, urethra, ureter, uterus)

[includes traumatic removal or insertion of foley]

MST 6Pelvis and Spine

Fracture of vertebral column, open or closed, with spinal cord injury

Fracture of vertebral column, sacrum, and coccyx open or closed, without spinal cord injury

Or unspecified spinal cord injury

Dislocation of vertebra open, cervical open or closed

Spinal cord injury w/o evidence of spinal bone injury

Injury to nerve roots

MST 7Upper Limb

Open fractures of bones of the arm

Open dislocation of shoulder or elbow

Traumatic amputation of arm and hand (complete or partial)

Injury to blood vessels of UE

Injury to nerves (brachial plexus, axillary, median, ulnar, radial)

MST 8 Lower Limb

Fracture of femur (open or closed)

Multi fx LE w/ UE, both LE, LE w/ sternum

Open dislocation of hip, knee, or ankle

Traumatic amputation of foot or leg (complete or partial)

Injury to femoral artery, femoral veins, popliteal or tibial blood vessels

Or other specified blood vessels of LE

CLASSIFICATIONS



Trauma can be classified by the affected body areas:

* POLYTRAUMA (40%)


* HEAD INJURY (30%)


* CHEST TRAUMA (20%)


* ABDOMINAL TRAUMA (10%)


* EXTREMITY TRAUMA (2%)





THINGS TO THINK ABOUT:

If Polytrauma is 40% of injuries; why are there not more MST DRGs?

* Remember the detail of the docu


* Use your clinical expertise >does the patient look sicker than the
documentation supports?


* Are the results of diagnostics appropriately and clearly documented?


* Are query opportunities identified?


* Are suspected conditions confirmed or ruled out?

* secondary conditions effecting level of care and resource consumption
documented? 






THINGS TO THINK ABOUT…


* missed injury? not found during initial assessment but manifested later?
(ie: traumatic foley insertion or removal could change the DRG to

MST)


* did the patient require one or more surgical interventions?

* EMT treatment/survey – life threatening injury

* ED treatments/survey – Complete inspection, systemic assessment

* Consults

* Diagnostics: CT, Xray, MRI

* Labs: Hematuria, ABG’s, CBC, Blood sugar elevation

* Procedures: paracentesis, pericardiaocentesis

*** All injuries do not have to be POA

Pt pulling out their foley causing urethral trauma, or

Traumatic insertion of an NG tube causing injury.

Any injury from a fall while in the hospital would not count as an MST qualifying injury.

***Additional injuries beyond qualifying for the MST DRG

DO NOT count as CC/MCC’s

Possible CC’s with MST

Acute Renal Failure

Acute Blood Loss Anemia

Atelectasis

Possible MCC’s with MST

Pneumonia

Respiratory Failure

Respiratory Arrest

Cardiac Arrest

Shock –

Hypovolemic, hemorrhagic, traumatic

PE

Quadriplegia

Possible Query opportunities if MST is suspected

Clarify LOC and the duration

Clarify the number of rib fractures

If there is broken skin consider clarifying:

Open or closed fractures

Open or closed dislocation

Laceration to underlying organ

If there is a contusion/ hematoma, blood transfusion, spreading ecchymosis, drop in H/H, fractured bone consider:

Injury to blood vessel

Contusion or laceration to underlying organ

Brain contusion (851)

Heart or lung contusion (861)

Injury to Liver

Injury to Spleen
