T88Other complications of surgical and medical care, not elsewhere classified

Non-billable headerICD-10-CM

T88 is a non-billable header ICD-10-CM code for other complications of surgical and medical care, not elsewhere classified. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.

This code requires a 7th character

The appropriate 7th character is to be added to each code from category T88

A
initial encounter
D
subsequent encounter
S
sequela

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

  • complication following infusion, transfusion and therapeutic injection (T80.-)
  • complication following procedure NEC (T81.-)
  • complications of anesthesia in labor and delivery (O74.-)
  • complications of anesthesia in pregnancy (O29.-)
  • complications of anesthesia in puerperium (O89.-)
  • complications of devices, implants and grafts (T82-T85)
  • complications of obstetric surgery and procedure (O75.4)
  • dermatitis due to drugs and medicaments (L23.3, L24.4, L25.1, L27.0-L27.1)
  • poisoning and toxic effects of drugs and chemicals (T36-T65 with fifth or sixth character 1-4)
  • specified complications classified elsewhere

Other codes that can never be billed with T88

These codes carry an Excludes1 note pointing at T88. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading T88 alone.

  • B08.011Vaccinia not from vaccine
  • R50Fever of other and unknown origin
  • R57Shock, not elsewhere classified
  • R68.0Hypothermia, not associated with low environmental temperature
  • T67Effects of heat and light
  • T68Hypothermia
  • T68.XXXAHypothermia, initial encounter
  • T68.XXXDHypothermia, subsequent encounter

Risk adjustment

T88 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead T88

10 child codes. Green means billable.
