What Medicare edits apply to M36.3?
The Medicare Code Editor screens inpatient claims before they are grouped. These edits name M36.3 directly.
This code describes a manifestation of an underlying disease. The underlying condition must be sequenced before it, so it can never be the principal or first-listed diagnosis.
Which MS-DRGs does M36.3 group to?
M36.3 sits in MDC 08 and helps define the logic of 2 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

Code first
The underlying condition below must be sequenced before M36.3. M36.3 describes a manifestation and cannot be the principal or first-listed diagnosis.
Excludes1 — never code together — inherited from M30-M36
The conditions below can never be reported together with M36.3 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- autoimmune disease, single organ or single cell-type -code to relevant condition category
Excludes2 — not included here — inherited from Chapter 13
The conditions below are not part of M36.3, but a patient may have both at the same time. When documentation supports it, M36.3 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 M36
The conditions below are not part of M36.3, but a patient may have both at the same time. When documentation supports it, M36.3 and the excluded code may both be reported.
- arthropathies in diseases classified elsewhere (M14.-)
How long has M36.3 existed?
M36.3 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.
Which codes are confused with M36.3?
ICD-10-CM declares these codes mutually exclusive with M36.3 — exactly one of each pair can be correct for a given encounter.
