E977Late effects of injuries due to legal intervention
- Legacy / Not Valid for Submission
- Replaced October 1, 2015
- External Cause (E Code)
E977 is a legacy ICD-9-CM external cause code (E code) that described late effects of injuries due to legal intervention. 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, it maps to 7 ICD-10-CM candidates: Y35.003S, Y35.103S, Y35.203S, Y35.303S, Y35.403S, Y35.893S, and Y35.93XS.

ICD-10-CM Replacement
Based on the final CMS General Equivalence Mappings (GEMs), E977 crosswalks to the following ICD-10-CM codes. When more than one candidate is listed, pick the code the documentation supports.

| Y35.103S | Legal intervnt w unsp explosv, suspect injured, sequela | Approximate |
| Y35.203S | Legal intervnt involving unsp gas, suspect injured, sequela | Approximate |
| Y35.303S | Legal intervnt w unsp blunt objects, suspect inj, sequela | Approximate |

Questions About E977
Is E977 (late effects of injuries due to legal intervention) 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 Y35.003S, Y35.103S, and Y35.203S.
What is the ICD-10 replacement for E977?
The General Equivalence Mappings list 7 ICD-10-CM candidates for this code: Y35.003S (Legal intervnt w unsp firearm disch, suspect inj, sequela), Y35.103S (Legal intervnt w unsp explosv, suspect injured, sequela), Y35.203S (Legal intervnt involving unsp gas, suspect injured, sequela), Y35.303S (Legal intervnt w unsp blunt objects, suspect inj, sequela), Y35.403S (Legal intervnt w unsp sharp objects, suspect inj, sequela), Y35.893S (Legal intervnt involving oth means, suspect injured, sequela), and Y35.93XS (Legal intervention, means unsp, suspect injured, sequela). Each match is approximate, so the right choice depends on what the documentation supports.
What did E977 mean?
In the final ICD-9-CM release, this code described late effects of injuries due to legal intervention. It sat in block E977 Late effects of injuries due to legal intervention under External causes of injury (V).
Why does E977 map to more than one ICD-10 code?
ICD-10-CM is more specific than ICD-9-CM. The detail packed into this single legacy code was split across Y35.003S, Y35.103S, Y35.203S, Y35.303S, Y35.403S, Y35.893S, and Y35.93XS, so the General Equivalence Mappings list every candidate rather than forcing one. The correct target is the one the documentation supports.
