Injury, unspecified, initial encounter 1 T14.90XA is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. 2 The 2020 edition of ICD-10-CM T14.90XA became effective on October 1, 2019. 3 This is the American ICD-10-CM version of T14.90XA - other international versions of ICD-10 T14.90XA may differ.
The ICD-10-CM guidelines define a sequela as “the residual effect (condition produced) after the acute phase of an illness or injury has terminated.” The general coding guidelines in ICD-10-CM for coding of sequelae are essentially the same as coding of late effects in ICD-9-CM and are as follows:
Injury, unspecified, initial encounter. 2018 - New Code 2019 2020 Billable/Specific Code. T14.90XA is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2020 edition of ICD-10-CM T14.90XA became effective on October 1, 2019.
For aftercare of an injury, coders should assign the acute injury code with the appropriate seventh character "D" (or expanded choices for fractures) for subsequent encounter. This change will be significant for those post-acute settings that provide subsequent care for injuries.

For example, if a patient with severe degenerative osteoarthritis of the hip, underwent hip replacement and the current encounter/admission is for rehabilitation, report code Z47. 1, Aftercare following joint replacement surgery, as the first-listed or principal diagnosis.
99024 - Postoperative follow-up visit, normally included in the surgical package, to indicate that an evaluation and management service was performed during a postoperative period for a reason(s) related to the original procedure.
ICD-10-CM Code for Complication of surgical and medical care, unspecified, initial encounter T88. 9XXA.
Code Z47. 1 (aftercare following joint replacement surgery) is used during the follow-up phase of any joint replacement surgery, even if the replacement was for treatment of a fracture.
The types of open wounds classified in ICD-10-CM are laceration without foreign body, laceration with foreign body, puncture wound without foreign body, puncture wound with foreign body, open bite, and unspecified open wound. For instance, S81. 812A Laceration without foreign body, right lower leg, initial encounter.
Non-healing wounds (ulcers) L89.
A non-healing wound is a wound that doesn't heal within five to eight weeks, even though you've been following your provider's instructions to take care of it. This can be very serious, because it can become infected and lead to an illness or even the loss of a limb.
Wound dehiscence is a surgery complication where the incision, a cut made during a surgical procedure, reopens. It is sometimes called wound breakdown, wound disruption, or wound separation. Partial dehiscence means that the edges of an incision have pulled apart in one or more small areas.
In ICD-10-CM, injuries are grouped by body part rather than by category, so all injuries of a specific site (such as head and neck) are grouped together rather than groupings of all fractures or all open wounds. Categories grouped by injury in ICD-9-CM such as fractures (800–829), dislocations (830–839), and sprains and strains (840–848) are grouped in ICD-10-CM by site, such as injuries to the head (S00–S09), injuries to the neck (S10–S19), and injuries to the thorax (S20–S29).
When coding a poisoning or reaction to the improper use of a medication (e.g., overdose, wrong substance given or taken in error, wrong route of administration), assign first the appropriate code from categories T36–T50. The sequencing for a toxic effect of substances chiefly nonmedicinal as to source (T51-T65) is the same as for coding poisonings. Poisoning codes have an associated intent: accidental, intentional self-harm, assault, and undetermined. Use additional code (s) for all manifestations of poisonings.
The S seventh character identifies the injury responsible for the sequela. The specific type of sequela (e.g., scar) is sequenced first, followed by the injury code. Sequela is the new terminology in ICD-10-CM for late effects in ICD-9-CM and using the sequela seventh character replaces the late effects categories (905–909) in ICD-9-CM.
For complication codes, active treatment refers to treatment for the condition described by the code, even though it may be related to an earlier precipitating problem. For example, code T84.50XA, Infection and inflammatory reaction due to unspecified internal joint prosthesis, initial encounter, is used when active treatment is provided for the infection, even though the condition relates to the prosthetic device, implant or graft that was placed at a previous encounter.
The following coding guidance is provided at the beginning of the chapter, "Use secondary code (s) from chapter 20, External Causes of Morbidity, to indicate cause of injury." Codes within the T section that include the external cause do not require an additional external cause code. The Official Coding Guidelines clarified the use of external cause codes in 2014. The guidelines state: “There is no national requirement for mandatory ICD-10-CM external cause code reporting. Unless a provider is subject to a state-based external cause code reporting mandate or these codes are required by a particular payer, reporting of ICD-10-CM codes in Chapter 20, External Causes of Morbidity, is not required. In the absence of a mandatory reporting requirement, providers are encouraged to voluntarily report external cause codes, as they provide valuable data for injury research and evaluation of injury prevention strategies.”
ICD-10-CM provides greater specificity in coding injuries than ICD-9-CM. While many of the coding guidelines for injuries remain the same as ICD-9-CM, ICD-10-CM does include some new features, such as seventh characters.
Background: In ICD-10, W16 Diving or Jumping into Water Causing Injury other than Drowning or Submersion consists of a single code and is placed in Unintentional Fall in the ICD-10 External Cause Matrix. In ICD-10-CM, W16 includes multiple codes for falling, jumping or diving into a swimming pool or natural body of water, with separate codes that specify drowning/submersion or other injuries. Similarly, in ICD-10, W22 Striking against or Struck by Other Objects consists of a single code and is placed in Unintentional Struck by/against in the ICD-10 External Cause Matrix. In ICD-10-CM, W22 includes multiple codes for striking against or struck by other objects, including two codes specific to striking against the wall of swimming pool causing drowning and submersion (W22.041) and other injury (W22.042).
Background: Most ICD-10-CM external cause-related codes (V, W, X, Y, and T) have a 7th character that indicates whether the code is associated with the initial encounter (A), subsequent encounter (D), or a sequela (S). The initial encounter character (A) is used while the patient is receiving active treatment (e.g., emergency department encounter, surgery, evaluation and treatment by a new physician) for the condition. The subsequent encounter character (D) is used for encounters after the patient has received active treatment for the condition and is receiving routine care for the injury during the healing or recovery phase. The sequela character (S) is used with any report of a late effect or sequela resulting from a previous injury.
External cause of injury frameworks based on the International Classification of Diseases (ICD) have served the injury field in providing standards for presenting and analyzing state, national and international injury mortality and morbidity data. The external cause of injury framework, commonly called the external cause matrix, categorizes ICD codes into major mechanism (e.g., motor vehicle-trac, cut/pierce, drowning, fall, firearm, fire/burn, natural/environmental, poisoning) by intent of injury (i.e., unintentional, self-harm, assault, legal intervention/war, undetermined) categories.
External cause of injury codes for intentional harm by other persons are referred to as Homicide and injury purposely inflicted by other persons
Both diagnosis and external cause of injury codes in the ICD-10-CM code set can have three to seven alphanumeric characters. The first character is always alpha, the second character is always numeric, and characters 3-7 are alpha or numeric. The first three characters of an ICD-10-CM code designate the general category in which the code belongs, which is further expanded in the fourth, fifth, and sixth characters to add more specific details on related etiology (mechanism and/or intent), anatomic site, and severity. For codes related to injury and overdose, the 7 th character denotes the encounter type (e.g., initial encounter, subsequent encounter, or sequelae). The character for encounter type must always be in the 7 th position, so if a code has less than 6 characters and requires a 7 th character extension, all of the empty character spaces should be filled with the placeholder “X”. A decimal is placed between the 3 rd and 4 th characters, however these decimals may be removed during the data cleaning and preparation stage.
External cause of injury codes for perpetrator of assault, maltreatment and neglect (Y07) are expanded; includes diagnosis codes to specify adult and child abuse, neglect, and other maltreatment, confirmed (T74) and suspected (T76)
40 diagnosis codes for asphyxiation or strangulation by different mechanisms and intents
Diagnosis codes (“S” and “T” codes), which contain information about the body region and nature of injury – for example left leg fracture or scalp laceration
Includes external cause of injury codes for perpetrator of child and adult abuse (E967.0-.9); includes diagnosis codes for child maltreatment and abuse (995.50-995.59) and adult maltreatment and abuse (995.80-.85)
This applies to overdose codes (T36-T50) and toxic effects codes (T51-T65) , where information about the drug or substance involved and the intent are captured a single code. There are several other “T” diagnosis codes that also contain external cause information. See table below.
When the reason for an encounter is aftercare following a procedure or injury, the 2012 ICD-10-CM Official Guidelines and Reporting should be consulted to ensure that the correct code is assigned. Codes for reporting most types of aftercare are found in Chapter 21. However, aftercare related to injuries is reported with codes from Chapter 19, using seventh-character extensions to identify the service as aftercare.
Reason for encounter: Aftercare for traumatic fracture is reported with code S82.224D, Nondisplaced transverse fracture of shaft of right tibia, subsequent encounter for closed fracture with routine healing.
Aftercare following explantation of a joint prosthesis is reported with a code from category Z47, denoting orthopedic aftercare. Aftercare following explantation of a joint prosthesis (Z47.3-) may be reported for a staged procedure or an encounter for evaluation of planned insertion of a new joint prosthesis following prior explantation of a joint prosthesis. In ICD-10-CM, aftercare for explantation of a joint prosthesis is specific to site.
Aftercare codes are found in categories Z42-Z49 and Z51. Aftercare is one of the 16 types of Z-codes covered in the 2012 ICD-10-CM Official Guidelines and Reporting. Aftercare visit codes cover situations occurring when the initial treatment of a disease has been performed and the patient requires continued care during the healing or recovery phase, or care for the long-term consequences of the disease.
Aftercare for injuries is reported with a V-code in ICD-9-CM. However, aftercare of injuries in ICD-10-CM is captured with the seventh character “D,” specifically denoting routine care following most injuries. For fractures, additional seventh characters for subsequent encounters apply, depending on whether the fracture is open or closed and whether the healing is routine or delayed, with nonunion or malunion.
The codes for factors influencing health and contact with health services represent reasons for encounters. In ICD-10-CM, these codes are located in Chapter 21 and have the initial alpha character of “Z,” so codes in this chapter eventually may be referred to as “Z-codes” (just as the same supplementary codes in ICD-9-CM were referred to as “V-codes”). While code descriptions in Chapter 21, such as aftercare, may appear to denote descriptions of services or procedures, they are not procedure codes. These codes represent the reason for the encounter, service or visit, and the procedure must be reported with the appropriate procedure code.
Codes for encounters for antineoplastic radiation, chemotherapy and immunotherapy (Z51.0, Z51.1-) are assigned if the sole reason for the encounter is antineoplastic therapy – even if the patient still has the neoplastic disease.
The ‘S’ is added only to the injury code, not the sequela code. The seventh character ‘S’ identifies the injury responsible for the sequela. The specific type of sequela (e.g. scar) is sequenced first, followed by the injury code.”.
Rationale: Scar contractures due to burn injury are reported with code L90.5 that is the first-listed or principal diagnosis and the burn injury is reported as a secondary code to identify the cause of the sequela.
There is no time limit on when a sequela code can be used. The residual effect may be present early or may occur months or years later. Two codes are generally required: one describing the nature of the sequela and one for the sequela. The code for the acute phase of the illness or injury is never reported with a code for the late effect.
The sequela code may also be expanded at the fourth, fifth, or sixth character levels to include the manifestation
