Guide & Verified Q&A
What is the Abbreviated Injury Scale (AIS)? - correct answer-An anatomically based international injury scaling system. Is there a strong correlation between AIS severity and survival? - correct answer- Yes How is an AIS code formatted? - correct answer-A seven-digit format, with the first six digits being the pre-dot code and the single digit after the dot being the post-dot digit or severity number. What does the pre-dot code represent? - correct answer-The body area of injury, the anatomical structure(s) involved, and the level of injury. What are the six main body regions in the AIS? - correct answer-1. Head/Neck, 2. Face, 3. Chest/Thorax, 4. Abdomen-Lumbar spine, 5. Extremities, shoulder and pelvic girdles, 6. External including burn, hypothermia, asphyxiation, drowning, electrocution, explosion full body.
What does the post-dot code represent? - correct answer-The severity of the injury. What are the numerical values assigned to the post-dot code? - correct answer-.
- Minor, .2 - Moderate, .3 - Serious, .4 - Severe, .5 - Critical, .6 - Maximum (not fatal, currently untreatable), .9 - Injury present but no severity value. What is the significance of a .6 post-dot code? - correct answer-It automatically indicates an ISS (Injury Severity Score) of 75 and other injuries should be coded but not added to this highest ISS total. What does AIS severity reflect? - correct answer-The severity of one injury for a patient 25-40 years old with no co-morbidities and with appropriate care. What does an ISS score reflect? - correct answer-Total value of up to 3 injuries. What do the first three characters of an ICD-10 code designate? - correct answer- Category of the diagnosis. What does the letter 'S' designate in an ICD-10 code? - correct answer-Injuries, poisoning, and certain other consequences of external causes related to single body regions. What does 'S8' indicate in an ICD-10 code? - correct answer-Injury of muscle, fascia, and tendon at lower leg.
What does the seventh character 'D' indicate? - correct answer-A sequela, a complication or condition resulting from an injury. What is ICD- 10 - CM? - correct answer-International Classification of Diseases, Tenth Revision, Clinical Modification. What are the 7th character modifiers for injuries to specific body parts - initial encounter? - correct answer-A, B, or C. What is the code for unspecified multiple injuries? - correct answer-T07. What is the code for injury of unspecified body region? - correct answer-T14. What are the 7th character modifiers for burns by specific body parts - initial encounter? - correct answer-A. What are the codes for burns by TBSA percentages? - correct answer-T30-T32. What are the 7th character modifiers for Traumatic Compartment Syndrome - initial encounter? - correct answer-A. Which superficial injuries are excluded from the ICD- 10 - CM codes? - correct answer-S00, S10, S20, S30, S40, S50, S60, S70, S80, S90. What are late effect codes? - correct answer-Codes representing the long-term effects or complications of an injury.
What are the 7th digit modifier codes for late effect codes? - correct answer-D through S. What must be included in addition to the specified ICD- 10 - CM codes? - correct answer-One of the following: S 00 - S99, T07, T14, T20-T28, T30-T32, and T79.A1- T79.A9. What is the Injury Severity Score (ISS)? - correct answer-A score that assesses the severity of multiple injuries by assigning an Abbreviated Injury Scale (AIS) score to each injury and allocating them to body regions. How is the ISS score calculated? - correct answer-The three most severe injuries in different body regions have their scores squared and added together to produce the ISS score. What is the range of the ISS score? - correct answer-The ISS score ranges from 1 to 75, with 9-15 considered mild, 16-25 considered moderate, and >25 considered severe. What happens if an injury is assigned an AIS of .6? - correct answer-The ISS score is automatically assigned to 75.4. What is the most widely used scoring system internationally? - correct answer- The ISS score is the most widely used scoring system internationally and correlates linearly with mortality, morbidity, hospital stay, and other measures of severity.
What does GCS stand for? - correct answer-Glasgow Coma Scale. What does GCS represent? - correct answer-Indication of brain function/impairment. What are the descriptors for GCS? - correct answer-Numerical values represent eye, verbal, and motor responses. What is the range for GCS? - correct answer- 3 - 15. What is the normal value for GCS? - correct answer-15. What does a GCS score of 1 mean for eye response? - correct answer-No eye opening. What does a GCS score of 1 mean for verbal response? - correct answer-No verbal response. What does a GCS score of 1 mean for motor response? - correct answer-No movement. What are the components used to calculate Trauma Score? - correct answer-GCS, Systolic BP, Respiratory Rate, Capillary Refill, and Respiratory Effort. What is the range for Trauma Score? - correct answer- 1 - 16.
What is TRISS? - correct answer-Probability of survival determined by ISS, RTS, and patient's age. What is the probability of survival if TRISS > 0.50? - correct answer-Probability of survival. What is the probability of survival if TRISS < 0.50? - correct answer-Probability of death. What are W Scores and Z Scores used for? - correct answer-Measuring clinical and statistical significance of outcome. What is the w value? - correct answer-Number of unexpected survivors per 100 admissions. What does a z value exceeding +1.96 indicate? - correct answer-Significantly more patients survived than predicted. What does a z value more negative than - 1.96 indicate? - correct answer- Significantly more patients died than predicted. What is the OIS? - correct answer-Organ Injury Scale. What is the Pelvic Injury Tables? - correct answer-Classification of pelvic fractures. What is the Lund-Browder Chart used for? - correct answer-Burn rule of 9's for burns.
AIS region 3 is? - correct answer-Chest/Thorax AIS region 4 is? - correct answer-Abdomen - Lumbar spine AIS region 5 is? - correct answer-Extremities, shoulder and pelvic girdles AIS region 6 is? - correct answer-External including burn, hypothermia, asphyxiation, drowning, electrocution, explosion full body
