M80.819P — Other osteoporosis with current pathological fracture, unspecified shoulder, subsequent encounter for fracture with malunion
Is M80.819P billable?
Yes, but M80.819P will trip a Medicare edit. M80.819P is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, CMS lists M80.819P under Medicare Code Editor edit 20, “Unspecified code” — meaning a code specifying laterality (right, left or bilateral) exists in the same family. On an inpatient claim this triggers the edit, because CMS holds that there are very limited circumstances in which laterality cannot be documented.

What Medicare edits apply to M80.819P?
The Medicare Code Editor screens inpatient claims before they are grouped. These edits name M80.819P directly.
A code specifying laterality (right, left or bilateral) exists in the same family. CMS holds that there are very limited circumstances in which laterality cannot be documented.
Which MS-DRGs does M80.819P group to?
M80.819P sits in MDC 08 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 564Other Musculoskeletal System and Connective Tissue Diagnoses with MCCmedical
- 565Other Musculoskeletal System and Connective Tissue Diagnoses with CCmedical
- 566Other Musculoskeletal System and Connective Tissue Diagnoses without CC/MCCmedical
As a secondary diagnosis, M80.819P is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

Excludes1 — never code together — inherited from M80
The conditions below can never be reported together with M80.819P on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Use additional code — inherited from M80
Report an additional code alongside M80.819P to fully describe the condition. M80.819P is sequenced first.
- code to identify major osseous defect, if applicable (M89.7-)
Use additional code — inherited from M80.8
Report an additional code alongside M80.819P to fully describe the condition. M80.819P is sequenced first.
- code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)
Excludes2 — not included here — inherited from Chapter 13
The conditions below are not part of M80.819P, but a patient may have both at the same time. When documentation supports it, M80.819P and the excluded code may both be reported.
- 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)
Excludes2 — not included here — inherited from M80
The conditions below are not part of M80.819P, but a patient may have both at the same time. When documentation supports it, M80.819P and the excluded code may both be reported.
- personal history of (healed) osteoporosis fracture (Z87.310)
How long has M80.819P existed?
M80.819P has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
