2021 ICD-10-CM Code T84.09

Other mechanical complication of internal joint prosthesis

Version 2021
Non-Billable Code

Not Valid for Submission

T84.09 is a "header" nonspecific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of other mechanical complication of internal joint prosthesis. The code is NOT valid for the year 2021 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Code Classification

Specific Coding for Other mechanical complication of internal joint prosthesis

Header codes like T84.09 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for other mechanical complication of internal joint prosthesis:

  • T84.090 - Other mechanical complication of internal right hip prosthesis
  • T84.090A - Other mechanical complication of internal right hip prosthesis, initial encounter
  • T84.090D - Other mechanical complication of internal right hip prosthesis, subsequent encounter
  • T84.090S - Other mechanical complication of internal right hip prosthesis, sequela
  • T84.091 - Other mechanical complication of internal left hip prosthesis
  • T84.091A - Other mechanical complication of internal left hip prosthesis, initial encounter
  • T84.091D - Other mechanical complication of internal left hip prosthesis, subsequent encounter
  • T84.091S - Other mechanical complication of internal left hip prosthesis, sequela
  • T84.092 - Other mechanical complication of internal right knee prosthesis
  • T84.092A - Other mechanical complication of internal right knee prosthesis, initial encounter
  • T84.092D - Other mechanical complication of internal right knee prosthesis, subsequent encounter
  • T84.092S - Other mechanical complication of internal right knee prosthesis, sequela
  • T84.093 - Other mechanical complication of internal left knee prosthesis
  • T84.093A - Other mechanical complication of internal left knee prosthesis, initial encounter
  • T84.093D - Other mechanical complication of internal left knee prosthesis, subsequent encounter
  • T84.093S - Other mechanical complication of internal left knee prosthesis, sequela
  • T84.098 - Other mechanical complication of other internal joint prosthesis
  • T84.098A - Other mechanical complication of other internal joint prosthesis, initial encounter
  • T84.098D - Other mechanical complication of other internal joint prosthesis, subsequent encounter
  • T84.098S - Other mechanical complication of other internal joint prosthesis, sequela
  • T84.099 - Other mechanical complication of unspecified internal joint prosthesis
  • T84.099A - Other mechanical complication of unspecified internal joint prosthesis, initial encounter

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code T84.09:


Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Index to Diseases and Injuries

The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code T84.09 are found in the index:

Information for Patients


Joint Disorders

A joint is where two or more bones come together, like the knee, hip, elbow, or shoulder. Joints can be damaged by many types of injuries or diseases, including

Treatment of joint problems depends on the cause. If you have a sports injury, treatment often begins with the RICE (Rest, Ice, Compression, and Elevation) method to relieve pain, reduce swelling, and speed healing. Other possible treatments include pain relievers, keeping the injured area from moving, rehabilitation, and sometimes surgery. For arthritis, injuries, or other diseases, you may need joint replacement surgery to remove the damaged joint and put in a new one.
