990Effects of radiation, unspecified
- Legacy / Not Valid for Submission
- Replaced October 1, 2015
990 is a legacy ICD-9-CM diagnosis code for effects of radiation, unspecified. It was valid on U.S. claims through September 30, 2015 and cannot be reported for services on or after October 1, 2015, when ICD-10-CM replaced the ICD-9 code set. Under the CMS General Equivalence Mappings, its ICD-10-CM replacement is T66.XXXA (Radiation sickness, unspecified, initial encounter), flagged as an approximate match.

Information for Patients
Radiation Exposure
Radiation is energy. It travels in the form of energy waves or high-speed particles. Radiation can occur naturally or be man-made. There are two types:

Questions About 990
Is 990 (effects of radiation, unspecified) still a valid code?
No. This code belonged to ICD-9-CM, which the United States retired after September 30, 2015. Claims with dates of service on or after October 1, 2015 must use ICD-10-CM codes, such as its replacement T66.XXXA.
What is the ICD-10 replacement for 990?
The General Equivalence Mappings crosswalk this code to ICD-10-CM T66.XXXA (Radiation sickness, unspecified, initial encounter). The match is flagged as approximate, so confirm it against the clinical documentation before use.
What did 990 mean?
In the final ICD-9-CM release, this code described effects of radiation, unspecified. It sat in block 990 Effects of radiation, unspecified under Injury and poisoning (800–999).
