Which MS-DRGs does H59.012 group to?

H59.012 sits in MDC 21 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.

  • 919Complications of Treatment with MCCmedical
  • 920Complications of Treatment with CCmedical
  • 921Complications of Treatment without CC/MCCmedical

As a secondary diagnosis, H59.012 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

Excludes1 — never code together — inherited from H59

The conditions below can never be reported together with H59.012 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • mechanical complication of intraocular lens (T85.2)
  • mechanical complication of other ocular prosthetic devices, implants and grafts (T85.3)
  • pseudophakia (Z96.1)
  • secondary cataracts (H26.4-)

Excludes2 — not included here — inherited from Chapter 7

The conditions below are not part of H59.012, but a patient may have both at the same time. When documentation supports it, H59.012 and the excluded code may both be reported.

  • certain conditions originating in the perinatal period (P04-P96)
  • certain infectious and parasitic diseases (A00-B99)
  • complications of pregnancy, childbirth and the puerperium (O00-O9A)
  • congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
  • diabetes mellitus related eye conditions (E09.3-, E10.3-, E11.3-, E13.3-)
  • endocrine, nutritional and metabolic diseases (E00-E88)
  • injury (trauma) of eye and orbit (S05.-)
  • 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)
  • syphilis related eye disorders (A50.01, A50.3-, A51.43, A52.71)

How long has H59.012 existed?

H59.012 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.
