T84 is a non-billable ICD-10-CM category code for complications of internal orthopedic prosthetic devices, implants and grafts, so it cannot be submitted on claims. Use a more specific code from this category instead, such as T84.010A, T84.010D, T84.010S, and T84.011A.

Coding GuidelinesGuidance

The appropriate 7th character is to be added to each code from block Complications of internal orthopedic prosthetic devices, implants and grafts (T84). Use the following options for the applicable episode of care:

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to T84: its own notes plus those printed at block T80-T88 and Chapter 19. A note printed at a category, block or chapter applies to every code under it.

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

On T84 itself
  • failure and rejection of transplanted organs and tissues (T86.-)
  • fracture of bone following insertion of orthopedic implant, joint prosthesis or bone plate (M96.6)
From Block T80-T88 Complications of surgical and medical care, not elsewhere classified applies to 1,683 codes
  • any encounters with medical care for postprocedural conditions in which no complications are present, such as:
  • artificial opening status (Z93.-)
  • closure of external stoma (Z43.-)
  • fitting and adjustment of external prosthetic device (Z44.-)
  • burns and corrosions from local applications and irradiation (T20-T32)

  • ventilator associated pneumonia (J95.851)
From Chapter 19 (S00-T88) Injury, poisoning and certain other consequences of external causes applies to 41,187 codes

Use Additional Code

Add a second code, after this one, to fully describe the condition.

From Block T80-T88 Complications of surgical and medical care, not elsewhere classified applies to 1,683 codes
  • code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)
  • code(s) to identify the specified condition resulting from the complication
  • code to identify devices involved and details of circumstances (Y62-Y82)
From Chapter 19 (S00-T88) Injury, poisoning and certain other consequences of external causes applies to 41,187 codes
  • code to identify any retained foreign body, if applicable (Z18.-)

Notes

General instructions on how these codes are used.

From Chapter 19 (S00-T88) Injury, poisoning and certain other consequences of external causes applies to 41,187 codes
  • 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 chapter uses the S-section for coding different types of injuries related to single body regions and the T-section to cover injuries to unspecified body regions as well as poisoning and certain other consequences of external causes.

7th Character

Every code in the category takes a 7th character from the listed values, with the placeholder X filling any empty positions before it.

  • The appropriate 7th character is to be added to each code from category T84
Values for category T84 Encounter: Initial, Subsequent, Sequela
  • Ainitial encounter
  • Dsubsequent encounter
  • Ssequela

Referenced in Other NotesGuidance

Instructional notes printed at other codes that name T84, its category, or a range that includes it.

Excludes2 2

These codes carry an Excludes2 note naming T84: its condition is not part of those codes, and both may be reported when the patient has both.

  • M96 Intraoperative and postprocedural complications and disorders of musculoskeletal system, not elsewhere classified
    complications of internal orthopedic prosthetic devices, implants and grafts (T84.-)
  • M96.6 Fracture of bone following insertion of orthopedic implant, joint prosthesis, or bone plate

Questions About T84Overview

Is T84 a billable code?

No. This is a category header that groups the codes for complications of internal orthopedic prosthetic devices, implants and grafts, and headers cannot be submitted on claims. Claims for complications of internal orthopedic prosthetic devices, implants and grafts need a more specific code from this category, such as T84.010A, T84.010D, and T84.010S.
