Inherited from T86Complications of transplanted organs and tissue
Use additional

code to identify other transplant complications, such as: graft-versus-host disease (D89.81-) malignancy associated with organ transplant (C80.2) post-transplant lymphoproliferative disorders (PTLD) (D47.Z1)

Inherited from T80-T88Complications of surgical and medical care, not elsewhere classified

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) complications of surgical procedures during pregnancy, childbirth and the puerperium (O00-O9A) mechanical complication of respirator [ventilator] (J95.850) poisoning and toxic effects of drugs and chemicals (T36-T65 with fifth or sixth character 1-4 or 6) postprocedural fever (R50.82) specified complications classified elsewhere, such as: cerebrospinal fluid leak from spinal puncture (G97.0) colostomy malfunction (K94.0-) disorders of fluid and electrolyte imbalance (E86-E87) functional disturbances following cardiac surgery (I97.0-I97.1) intraoperative and postprocedural complications of specified body systems (D78.-, E36.-, E89.-, G97.3-, G97.4, H59.3-, H59.-, H95.2-, H95.3, I97.4-, I97.5, J95.6-, J95.7, K91.6-, L76.-, M96.-, N99.-) ostomy complications (J95.0-, K94.-, N99.5-) postgastric surgery syndromes (K91.1) postlaminectomy syndrome NEC (M96.1) postmastectomy lymphedema syndrome (I97.2) postsurgical blind-loop syndrome (K91.2) ventilator associated pneumonia (J95.851)

Use additional

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 19Injury, poisoning and certain other consequences of external causes
Excludes 2

birth trauma (P10-P15) obstetric trauma (O70-O71)

Use additional

code to identify any retained foreign body, if applicable (Z18.-)

Note

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. (T07-T88) Injury, poisoning and certain other consequences of external causes (T07-T88) (T20-T32) Burns and corrosions (T20-T32) Includes: burns (thermal) from electrical heating appliances burns (thermal) from electricity burns (thermal) from flame burns (thermal) from friction burns (thermal) from hot air and hot gases burns (thermal) from hot objects burns (thermal) from lightning burns (thermal) from radiation chemical burn [corrosion] (external) (internal) scalds Excludes2: erythema [dermatitis] ab igne (L59.0) radiation-related disorders of the skin and subcutaneous tissue (L55-L59) sunburn (L55.-)
