There will be a whole new set under the S06.0 heading.
Don’t be alarmed, but you’re about a month from having to use the new and revised ICD-10 codes that take effect for 2022 (and forgetting about the deleted codes).
Remember, the new codes will go into effect on Oct. 1, 2021 — well before most coders can get their hands on an official ICD-10 2022 manual. That can make using the new codes challenging, especially in the first few months.
Help’s here: Last month, we listed the new, revised and deleted codes for 2022. This month, we’re going to take a longer look at some of the additions, and how they’ll affect your diagnosis coding in 2022. We’ll also give a look into how the new codes will fit into their existing code families, and examine changes in verbiage to the new codes.
Additions Include Cervicogenic Headache Code
One of the new codes you’ll want to acquaint yourself with is G44.86 (Cervicogenic headache).
What’s the difference? Under the G44.8 (Other specified headache syndromes) in ICD-10 2022, the code list will look like this (new codes in bold):
- G44.81 (Hypnic headache)
- G44.82 (Headache associated with sexual activity)
- G44.83 (Primary cough headache)
- G44.84 (Primary exertional headache)
- G44.85 (Primary stabbing headache)
- G44.86 (Cervicogenic headache)
- G44.89 (Other headache syndrome).
So starting in October, you should report G44.86 for cervicogenic headache rather than G44.89.

Toxic Encephalopathy Changed to Neurotoxicity Syndrome
ICD-10 2022 will also greatly expand the G92 (Toxic encephalopathy) options, from a single code to 10. It also introduces verbiage more specific to each condition, so coding for patients with these conditions will be much more accurate in 2022.
In 2022, all of these new codes will appear under G92:
- G92.0 (Immune effector cell-associated neurotoxicity syndrome)
- G92.00 (Immune effector cell-associated neurotoxicity syndrome, grade unspecified)
- G92.01 (Immune effector cell-associated neurotoxicity syndrome, grade 1)
- G92.02 (Immune effector cell-associated neurotoxicity syndrome, grade 2)
- G92.03 (Immune effector cell-associated neurotoxicity syndrome, grade 3)
- G92.04 (Immune effector cell-associated neurotoxicity syndrome, grade 4)
- G92.05 (Immune effector cell-associated neurotoxicity syndrome, grade 5)
- G92.8 (Other toxic encephalopathy)
- G92.9 (Unspecified toxic encephalopathy).
What’s the difference? In 2021, the only code for this condition was the much vaguer G92. Now, coders can dig into the notes and assign a more specific ICD-10 code, which can improve patient care and coding accuracy.
M45 Code Set Expands Greatly
ICD-10 2022 will also add a slew of new codes to the M45 (Ankylosing spondylitis) code set. Further, the set breaks spondyloarthritis into two separate types: non-radiographic axial and ankylosing.
What’s the difference? The order might be different in the final publication, but under the M45 in ICD-10 2022, the code list will look like this (new codes in bold):
- M45.A (Non-radiographic axial spondyloarthritis)
- M45.0 (Ankylosing spondylitis of multiple sites in spine)
- M45.A0 (Non-radiographic axial spondyloarthritis of unspecified sites in spine)
- M45.1 (Ankylosing spondylitis of occipito-atlanto-axial region)
- M45.A1 (Non-radiographic axial spondyloarthritis of occipito-atlanto-axial region)
- M45.2 (Ankylosing spondylitis of cervical region)
- M45.A2 (Non-radiographic axial spondyloarthritis of cervical region)
- M45.3 (Ankylosing spondylitis of cervicothoracic region)
- M45.A3 (Non-radiographic axial spondyloarthritis of cervicothoracic region)
- M45.4 (Ankylosing spondylitis of thoracic region)
- M45.A4 (Non-radiographic axial spondyloarthritis of thoracic region)
- M45.5 (Ankylosing spondylitis of thoracolumbar region)
- M45.A5 (Non-radiographic axial spondyloarthritis of thoracolumbar region)
- M45.6 (Ankylosing spondylitis lumbar region)
- M45.A6 (Non-radiographic axial spondyloarthritis of lumbar region)
- M45.7 (Ankylosing spondylitis of lumbosacral region)
- M45.A7 (Non-radiographic axial spondyloarthritis of lumbosacral region)
- M45.8 (Ankylosing spondylitis sacral and sacrococcygeal region)
- M45.A8 (Non-radiographic axial spondyloarthritis of sacral and sacrococcygeal region)
- M45.AB (Non-radiographic axial spondyloarthritis of multiple sites in spine)
- M45.9 (Ankylosing spondylitis of unspecified sites in spine).

Back Pain Gets 3 Additions
ICD-10 2022 will also aim for greater specificity for patients with low back pain; the 2021 ICD-10 code book only lists a single code under M54.5 (Low back pain).
In 2022, this trio of new codes will premiere under M54.5:
- M54.50 (Low back pain, unspecified)
- M54.51 (Vertebrogenic low back pain)
- M54.59 (Other low back pain).
Say Hello to S06.A
While most of the ICD-10 2022 additions will round out a code family and make the diagnoses more specific, some of the additions represent entire new code sets, not just additions to existing ones. In October, the S06.0 (Intracranial injury) code family will feature this list of all-new codes:
- S06.A (Traumatic brain compression and herniation)
- S06.A0 (Traumatic brain compression without herniation)
- S06.A0XA (Traumatic brain compression without herniation, initial encounter)
- S06.A0XD (Traumatic brain compression without herniation, subsequent encounter)
- S06.A0XS (Traumatic brain compression without herniation, sequela)
- S06.A1 (Traumatic brain compression with herniation)
- S06.A1XA (Traumatic brain compression with herniation, initial encounter)
- S06.A1XD (Traumatic brain compression with herniation, subsequent encounter)
- S06.A1XS (Traumatic brain compression with herniation, sequela).
