Coding instructions
Official Tabular Instructional Notes: the inclusion, exclusion and sequencing notes published for M50 in the official ICD-10-CM tabular list, quoted as published.
Source: CMS/CDC — ICD-10-CM Tabular ListRelease: FY2026Effective: October 1, 2025
Notes without a marker are published on M50 itself; “inherited from” names the category or block whose note applies here.
Includes
Conditions the official ICD-10-CM tabular list includes under this code.
- cervicothoracic disc disorders with cervicalgia
- cervicothoracic disc disorders
Excludes1 — Not Coded Here
Conditions generally not reported together with this code (Excludes1) -- an error unless the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).

Coder workflow for M50
MedCoder structured workflow — derived from this code’s own official record
Before you code M50
- M50 is not reportable as written. Select the more specific code beneath it that the documentation supports. Codes are reported to the highest level of specificity the classification provides (Guidelines I.B.2).
ReviewM50.0, M50.1, M50.2, M50.3, M50.8, M50.9
See the relationships section · Guide: How to choose an ICD-10-CM code →
- Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with M50. Excludes1 conditions are not reported together with this code unless the record shows they are unrelated (Guidelines I.A.12.a).
Choose the right path
- Does the documentation support one of the more specific codes beneath M50?
Yes → Select that code and continue the checks below on its own page.
No → M50 cannot be reported as written; query for the specificity its subcategory needs. - Does the documentation support a condition named in M50’s Excludes1 note?
Yes → Do not simply proceed: review the excluded code. Both are reported only when the record shows the two conditions are unrelated.
No → Continue.ReviewM46.4
Consider M50. Then confirm the code is valid for the date of service in the Verify section.
Documentation check
- The provider’s diagnostic statement
- Codes are assigned from the provider’s documented diagnosis, not from clinical criteria, test values or a medication list (Guidelines I.A.19).
Official instructions as workflow
Excludes1 — check before selecting M50(2 notes)
Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with M50: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.

Coding decision scenarios
Pattern scenarios for this code’s structure — decision rules, not clinical cases
Documentation: Both the condition M50 describes and a condition named in its Excludes1 note are documented for the same encounter.
Coding question: Can both codes be reported?
Path: Review the Excludes1 note and the excluded code, and look for a provider statement on whether the two conditions are related.
Reason: Excludes1 means the two are not coded together; the exception is when the record shows the conditions are unrelated to each other (Guidelines I.A.12.a).
ReviewM46.4
Every row is derived from this code’s own record — its title, tabular notes, 7th-character family and same-category siblings — with fixed MedCoder wording; nothing is inferred about a patient. The official notes and guideline text are in the sections each row links to, and they control.

Relationships & Classification
MedCoder structured relationships — computed from published CMS and AHRQ datasets
Other codes that name M50 or its code family, from the CMS ICD-10-CM tabular instructional notes. Tabular-note edges are stored at the code family level that carries each note.
Referenced by 3 Excludes1 notes across 3 chapters: G54 — Nerve root and plexus disorders, M54.2 — Cervicalgia, S13.0 — Traumatic rupture of cervical intervertebral disc.
These codes’ tabular lists mark this diagnosis as mutually exclusive — not reported together unless the conditions are documented as unrelated.
Referenced by 9 Excludes2 notes: M20 — Acquired deformities of fingers and toes, M20-M25 — Other joint disorders (M20-M25), M21 — Other acquired deformities of limbs, M22 — Disorder of patella, M23 — Internal derangement of knee, M24 — Other specific joint derangements, M25 — Other joint disorder, not elsewhere classified, M51 — Thoracic, thoracolumbar, and lumbosacral intervertebral disc disorders, M53.1 — Cervicobrachial syndrome.
These codes’ tabular lists name this diagnosis as distinct — both may be reported when both are documented.

Can M50 be billed directly?
No. M50 (Cervical disc disorders) is a non-billable ICD-10-CM category code. A more specific billable subcode must be selected based on clinical documentation.
