Which MS-DRGs does S32.451B group to?

S32.451B 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.

  • 521Hip Replacement with Principal Diagnosis of Hip Fracture with MCCsurgical
  • 522Hip Replacement with Principal Diagnosis of Hip Fracture without MCCsurgical

As a secondary diagnosis, S32.451B is a major complication or comorbidity (MCC), which can move a stay into a higher-paying DRG. It also carries Hospital-Acquired Condition category 05.

How is S32.451B listed in the Alphabetic Index?

Excludes1 — never code together — inherited from S32

The conditions below can never be reported together with S32.451B on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • transection of abdomen (S38.3)

Code first — inherited from S32

The underlying condition below must be sequenced before S32.451B. S32.451B describes a manifestation and cannot be the principal or first-listed diagnosis.

  • any associated spinal cord and spinal nerve injury (S34.-)

Use additional code — inherited from Chapter 19

Report an additional code alongside S32.451B to fully describe the condition. S32.451B is sequenced first.

  • code to identify any retained foreign body, if applicable (Z18.-)

Excludes2 — not included here — inherited from Chapter 19

The conditions below are not part of S32.451B, but a patient may have both at the same time. When documentation supports it, S32.451B and the excluded code may both be reported.

  • birth trauma (P10-P15)
  • obstetric trauma (O70-O71)

Excludes2 — not included here — inherited from S30-S39

The conditions below are not part of S32.451B, but a patient may have both at the same time. When documentation supports it, S32.451B and the excluded code may both be reported.

  • burns and corrosions (T20-T32)
  • effects of foreign body in anus and rectum (T18.5)
  • effects of foreign body in genitourinary tract (T19.-)
  • effects of foreign body in stomach, small intestine and colon (T18.2-T18.4)
  • frostbite (T33-T34)
  • insect bite or sting, venomous (T63.4)

Excludes2 — not included here — inherited from S32

The conditions below are not part of S32.451B, but a patient may have both at the same time. When documentation supports it, S32.451B and the excluded code may both be reported.

Code also — inherited from S32.4

Two codes may be needed to describe the condition fully. Whether S32.451B is sequenced first depends on the reason for the encounter.

  • any associated fracture of pelvic ring (S32.8-)

How long has S32.451B existed?

S32.451B 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.
