S24.142A vs S24.142D
S24.142A (Brown-Séquard syndrome at T2-T6 level of thoracic spinal cord, initial encounter) compared with S24.142D (Brown-Séquard syndrome at T2-T6 level of thoracic spinal cord, subsequent encounter), from the official CMS tabular data. S24.142A and S24.142D code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S24.142A and S24.142D code the same injury at a different phase of treatment, set by the 7th character.
The 7th character records the type of care given at the encounter being coded (ICD-10-CM Official Guidelines, Section I.C.19.a), so one encounter takes one of these, not both.
