ICD-9 Code for:: Open brain lacer-concuss

Convert 851.99 to ICD-10-CM

The following crosswalk between ICD-9-CM to ICD-10-CM is based based on the General Equivalence Mappings (GEMS) information:

S06.330A - Contus/lac cereb, w/o loss of consciousness, init (combination) Combination Flag
The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.
S06.339A - Contus/lac cereb, w LOC of unsp duration, init (combination) Combination Flag
The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.
S01.90XA - Unsp open wound of unspecified part of head, init encntr (combination) Combination Flag
The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.

ICD-9 Footnotes

General Equivalence Map Definitions
The ICD-9 and ICD-10 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

Approximate Flag - The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
No Map Flag - The no map flag indicates that a code in the source system is not linked to any code in the target system.
Combination Flag - The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.
