M88 — Osteitis deformans [Paget's disease of bone]
Is M88 billable?
No — M88 is a non-billable header code. M88 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 26 billable codes beneath M88.

Excludes1 — never code together
The conditions below can never be reported together with M88 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- osteitis deformans in neoplastic disease (M90.6)
Excludes1 — never code together — inherited from M86-M90
The conditions below can never be reported together with M88 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- postprocedural osteopathies (M96.-)
Excludes2 — not included here — inherited from Chapter 13
The conditions below are not part of M88, but a patient may have both at the same time. When documentation supports it, M88 and the excluded code may both be reported.

- 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)
