Which MS-DRGs does M84.333P group to?
M84.333P 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, M84.333P is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

- Fracture, traumatic › stress › ulna (abduction) (adduction) (separation)
Excludes1 — never code together — inherited from M84.3
The conditions below can never be reported together with M84.333P 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 M84.3
Report an additional code alongside M84.333P to fully describe the condition. M84.333P is sequenced first.
- external cause code(s) to identify the cause of the stress fracture
Excludes2 — not included here — inherited from Chapter 13
The conditions below are not part of M84.333P, but a patient may have both at the same time. When documentation supports it, M84.333P 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-)

- 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 M84
The conditions below are not part of M84.333P, but a patient may have both at the same time. When documentation supports it, M84.333P and the excluded code may both be reported.
- traumatic fracture of bone-see fracture, by site
Excludes2 — not included here — inherited from M84.3
The conditions below are not part of M84.333P, but a patient may have both at the same time. When documentation supports it, M84.333P and the excluded code may both be reported.
How long has M84.333P existed?
M84.333P 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.
