What is medical billing code 998?

Answer 1

Diagnosis code 998 is for other complications of procedures, not elsewhere classified. It excludes fluid overload due to blood transfusion, or TACO (transfusion associated circulatory overload). Code 998.0 is for postoperative shock which happened either during or resulting from a surgical procedure, but it excludes shock: anaphylactic due to serum; anesthetic; electric; following abortion; obstetric or traumatic. Code 998.00 is used for postoperative shock, unspecified, such as collapse, not otherwise specified, during or resulting from a surgical procedure or failure of peripheral circulation, postoperative. Diagnosis code 998 isn't a complete code...it must have 4 digits for more specificity. You can have 998.0 all the way to 998.9, but for most of those categories, you must choose a 5th digit. For example under category 998 I chose 998.5 which is for Postoperative Infection. Under that title, I chose 998.59 which is for "other postoperative infection".
