What does M54.2 mean?
M54.2 is the ICD-10-CM code for cervicalgia, which is neck pain. It covers pain localized to the cervical spine when no more specific cause is documented, and it is one of the two or three most used diagnosis codes in chiropractic practice.
Searchers reach this page as the neck pain ICD 10 code, cervicalgia meaning, and the diagnosis code for neck pain. They are all M54.2.
When does a chiropractor use M54.2?
The default code for a neck pain presentation before imaging or exam findings justify something more specific. It carries a claim on its own for most commercial payers, but the moment the note documents radiating arm symptoms, disc involvement, or a trauma mechanism, a more specific code tells the truth better and defends the visit level. A chart that stays on M54.2 for months while the note describes radiculopathy is a mismatch reviewers notice.
Coding rules that matter
- ✓Excludes cervicalgia due to intervertebral disc disorder, which belongs in the M50 family instead
- ✓No laterality and no seventh character; the code is complete at four characters
- ✓If the pain follows an injury, the S13 or S16 injury codes describe the case better and support personal injury documentation
The codes around M54.2
| Code | Description |
|---|---|
| M54.2 | Cervicalgia (this code) |
| M54.11 | Radiculopathy, occipito-atlanto-axial region |
| M54.12 | Radiculopathy, cervical region |
| M54.13 | Radiculopathy, cervicothoracic region |
| M50.30 | Other cervical disc degeneration, unspecified level |
| M53.1 | Cervicobrachial syndrome |
When M54.2 is the wrong code
Do not use M54.2 when the pain radiates into the arm in a nerve pattern, which is M54.12, or when a documented cervical disc condition explains it, which moves the case to the M50 family. Trauma cases with a mechanism belong on S13.4XXA or S16.1XXA, because M54.2 says nothing about how the neck got hurt, and in an injury claim that silence costs the case its story.
How does M54.2 work on Medicare chiropractic claims?
Medicare wants the subluxation code first: M99.01 for the cervical region leads the claim as primary, with M54.2 as the secondary diagnosis naming the condition treated. M54.2 alone, without the M99 pairing, is a common cause of chiropractic CMT denials on Medicare claims. The AT modifier still rides the CMT line for active treatment.
Where claims go wrong
Staying on M54.2 after the documentation has outgrown it; billing Medicare with M54.2 as the only diagnosis; pointing therapy lines performed on other regions at this cervical code.
How Cervica helps with M54.2
Cervica validates diagnosis pointers line by line before a claim goes out, checks the Medicare subluxation pairing and region agreement automatically, and carries diagnoses forward from the SOAP note so the claim always matches what the documentation actually says.
