M02.159Postdysenteric arthropathy, unspecified hip

BillableUnspecifiedCC

Is M02.159 billable?

Yes, but M02.159 will trip a Medicare edit. M02.159 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, CMS lists M02.159 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 M02.159?

The Medicare Code Editor screens inpatient claims before they are grouped. These edits name M02.159 directly.

Unspecified — a laterality-specific code exists — MCE edit 20

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 M02.159 group to?

M02.159 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.

  • 553Bone Diseases and Arthropathies with MCCmedical
  • 554Bone Diseases and Arthropathies without MCCmedical

As a secondary diagnosis, M02.159 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

How is M02.159 listed in the Alphabetic Index?

The Alphabetic Index lists these routes under M02.15, the nearest indexed parent of M02.159. Use them to find the family, then select the specific code.

Excludes1 — never code together — inherited from M02

The conditions below can never be reported together with M02.159 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • Behçet's disease (M35.2)
  • direct infections of joint in infectious and parasitic diseases classified elsewhere (M01.-)
  • postmeningococcal arthritis (A39.84)
  • mumps arthritis (B26.85)
  • rubella arthritis (B06.82)
  • syphilis arthritis (late) (A52.77)
  • rheumatic fever (I00)
  • tabetic arthropathy [Charcôt's] (A52.16)

Code first — inherited from M02

The underlying condition below must be sequenced before M02.159. M02.159 describes a manifestation and cannot be the principal or first-listed diagnosis.

  • underlying disease, such as:
  • congenital syphilis [Clutton's joints] (A50.5)
  • enteritis due to Yersinia enterocolitica (A04.6)
  • infective endocarditis (I33.0)
  • viral hepatitis (B15-B19)

Excludes2 — not included here — inherited from Chapter 13

The conditions below are not part of M02.159, but a patient may have both at the same time. When documentation supports it, M02.159 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)

How long has M02.159 existed?

M02.159 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.
