Coding GuidelinesGuidance

The appropriate 7th character is to be added to each code from block Other complications of surgical and medical care, not elsewhere classified (T88). Use the following options for the applicable episode of care:

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

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 T88
Values for category T88 Encounter: Initial, Subsequent, Sequela

Questions About T88Overview

Is T88 a billable code?

No. This is a category header that groups the codes for other complications of surgical and medical care, not elsewhere classified, and headers cannot be submitted on claims. Claims for other complications of surgical and medical care, not elsewhere classified need a more specific code from this category, such as T88.0XXA, T88.0XXD, and T88.0XXS.
