M67 is a non-billable ICD-10-CM category code for other disorders of synovium and tendon, so it cannot be submitted on claims. Use a more specific code from this category instead, such as M67.00, M67.01, M67.02, and M67.20.

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to M67: its own notes plus those printed at Chapter 13. A note printed at a category, block or chapter applies to every code under it.

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

  • palmar fascial fibromatosis [Dupuytren] (M72.0)
  • tendinitis NOS (M77.9-)
  • xanthomatosis localized to tendons (E78.2)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Chapter 13 (M00-M99) Diseases of the musculoskeletal system and connective tissue applies to 6,687 codes
  • arthropathic psoriasis (L40.5-)
  • certain conditions originating in the perinatal period (P04-P96)
  • certain infectious and parasitic diseases (A00-B99)
  • compartment syndrome (traumatic) (T79.A-)
  • complications of pregnancy, childbirth and the puerperium (O00-O9A)
  • congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
  • endocrine, nutritional and metabolic diseases (E00-E88)
  • injury, poisoning and certain other consequences of external causes (S00-T88)
  • neoplasms (C00-D49)
  • symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)

Notes

General instructions on how these codes are used.

From Chapter 13 (M00-M99) Diseases of the musculoskeletal system and connective tissue applies to 6,687 codes
  • Use an external cause code following the code for the musculoskeletal condition, if applicable, to identify the cause of the musculoskeletal condition

Questions About M67Overview

What is the ICD-10 code for other disorders of synovium and tendon?

M67 is the ICD-10-CM category for other disorders of synovium and tendon, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is M67 (Other disorders of synovium and tendon) a billable code?

No. This is a category header that groups the codes for other disorders of synovium and tendon, and headers cannot be submitted on claims. Claims for other disorders of synovium and tendon need a more specific code from this category, such as M67.00, M67.01, and M67.02.

Can M67 be reported with M72.0?

Not as a rule. The Excludes1 note on M67 lists "palmar fascial fibromatosis [Dupuytren] (M72.0)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
