T85.79
Infection and inflammatory reaction due to other internal prosthetic devices, implants and grafts
Non-billable headerNot valid on its own. Use one of the more specific codes under it.
T85.79 is a non-billable ICD-10-CM code header for infection and inflammatory reaction due to other internal prosthetic devices, implants and grafts. Report a more specific code from it instead. It is part of the FY2027 code set, effective October 1, 2026. A 7th character is required to complete the code. Its coding notes include a Use additional code instruction and 24 Excludes2 entries.
7th character
Category T85 requires a 7th character. T85.79 has only 5 characters, so a placeholder X fills the 6th position.

Guidelines tips
From the FY2027 Official Guidelines. ICD10Ref adds no rules of its own.
The 7th character depends on whether the patient is in active treatment, not on who sees the patient. An aftercare Z code is not used for injury aftercare.
A complication code needs the provider's documented cause-and-effect link between the care and the condition. Some T codes already include the type of procedure, so no external cause code is needed.
Use additional code
Add the listed code as a secondary code, if known.
Inherited from T85.7 Infection and inflammatory reaction due to other internal prosthetic devices, implants and grafts
- code to identify infection
Also from chapter/block level (4 notes)
Inherited from T80–T88 Complications of surgical and medical care, not elsewhere classified
- 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)
Inherited from Chapter 19 Injury, poisoning and certain other consequences of external causes
- code to identify any retained foreign body, if applicable (Z18.-)
Excludes2
Not included here. Both codes may be reported if the patient has both conditions.
Inherited from T85 Complications of other internal prosthetic devices, implants and grafts

- ventilator associated pneumonia (J95.851)
Inherited from Chapter 19 Injury, poisoning and certain other consequences of external causes
- birth trauma (P10-P15)
- obstetric trauma (O70-O71)
Notes
Also from chapter/block level (2 notes)
Inherited from Chapter 19 Injury, poisoning and certain other consequences of external causes
- 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.
