Note
- The chapter uses the S-section for coding different types of injuries related to single body regions and the T-section to cover injuries to multiple or unspecified body regions as well as poisoning and certain other consequences of external causes.Where multiple sites of injury are specified in the titles, the word "with" indicates involvement of both sites, and the word "and" indicates involvement of either or both sites.The principle of multiple coding of injuries should be followed wherever possible.Combination categories for multiple injuries is provided for use when there are insufficient detail as to the nature of the individual conditions, or for primary tabulation purposes when it is more convenient to record single code; otherwise, the component injuries should be coded separately.Reference should also be made to the coding rules and guidelines.The blocks of the S-section as well as (T00-T14 and T90-T98) contain injuries at the three-character level classified by type as follows:Superficial injury including:abrasionblister (nonthermal)contusion, including bruise and haematomainjury from superficial foreign body (splinter) without major open woundinsect bite (nonvenomous)Open wound including:animal bitecutlacerationpuncture wound:• NOS• with (penetrating) foreign bodyFracture including:Fracture:closed: comminuted, depressed, elevated, fissured, greenstick, impacted, linear, simple, slipped epiphysis, spiral — with or without delayed healingdislocateddisplacedFracture:open: compound, infected, missile, puncture, with foreign body — with or without delayed healingExcludes:malunion of fracture (M84.0)nonunion of fracture [pseudoarthrosis] (M84.1)pathological fracture (M84.4):• with osteoporosis (M80.-)stress fracture (M84.3)Dislocation, sprain and strain including:avulsion, laceration, sprain, strain, traumatic: haemarthosis, rupture, subluxation, tear of cartilage, joint (capsule), ligamentInjury to nerves and spinal cord including:complete or incomplete lesion of spinal cordlesion incontinuity of nerves and spinal cordtraumatic:• division of nerve• haematomyelia• paralysis (transient)• paraplegia• quadriplegiaInjury to blood vessels includingavulsion, cut, laceration, traumatic: aneurysm or fistula (arteriovenous), arterial haematoma, rupture of blood vesselsInjury of muscle, fascia and tendon including:avulsion, cut, laceration, strain, traumatic rupture of muscle, fascia and tendonCrushing InjuryTraumatic amputationInjury to internal organs including:blast injuries, bruise, concussion injuries, crushing, laceration, traumatic: haematoma, puncture, rupture, tear of internal organsOther and unspecified injuriesFrom Chapter 19: Injury, poisoning and certain other consequences of external causes (S00-T98)
