What Medicare edits apply to G73.7?

The Medicare Code Editor screens inpatient claims before they are grouped. These edits name G73.7 directly.

Manifestation code — never sequenced first — MCE edit 6

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 G73.7 group to?

G73.7 sits in MDC 01 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.

Excludes1 — never code together

The conditions below can never be reported together with G73.7 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

Code first

The underlying condition below must be sequenced before G73.7. G73.7 describes a manifestation and cannot be the principal or first-listed diagnosis.

  • underlying disease, such as:
  • glycogen storage disease (E74.0-)
  • hyperparathyroidism (E21.0, E21.3)
  • hypoparathyroidism (E20.-)
  • lipid storage disorders (E75.-)

Excludes2 — not included here — inherited from Chapter 6

The conditions below are not part of G73.7, but a patient may have both at the same time. When documentation supports it, G73.7 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)
  • 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 G73.7 existed?

G73.7 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 G73.7?

ICD-10-CM declares these codes mutually exclusive with G73.7 — exactly one of each pair can be correct for a given encounter.
