Final answer:
The ICD-10 code for pain management should begin with a code from category G89, followed by a code specifying the exact site of pain. For acute neck pain due to trauma, the codes would be G89.11 for Acute pain due to trauma, then M54.2 for Cervicalgia.
Step-by-step explanation:
The ICD-10 code for the sequencing of category G89 codes with site-specific pain codes is dependent on the context of the medical encounter. When the encounter is for pain control or pain management, the correct approach is to assign a code from category G89 first, followed by a code that identifies the specific site of pain.
For instance, if a patient comes for pain management due to acute neck pain resulting from trauma, you would first use the code G89.11, which indicates Acute pain due to trauma, and then add the code M54.2, which represents Cervicalgia, to specify the site of the pain.
