What does the 7th character "M" mean in S72.045M?
In S72.045M, the 7th character M means subsequent encounter for open fracture type I or II with nonunion. The 7th character is required for S72.045M to be a valid, complete code.

Which MS-DRGs does S72.045M group to?
S72.045M 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, S72.045M is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
How is S72.045M listed in the Alphabetic Index?
The Alphabetic Index lists these routes under S72.04, the nearest indexed parent of S72.045M. Use them to find the family, then select the specific code.

Excludes1 — never code together — inherited from S72
The conditions below can never be reported together with S72.045M on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- traumatic amputation of hip and thigh (S78.-)
Use additional code — inherited from Chapter 19
Report an additional code alongside S72.045M to fully describe the condition. S72.045M 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 S72.045M, but a patient may have both at the same time. When documentation supports it, S72.045M and the excluded code may both be reported.
Excludes2 — not included here — inherited from S70-S79
The conditions below are not part of S72.045M, but a patient may have both at the same time. When documentation supports it, S72.045M and the excluded code may both be reported.
Excludes2 — not included here — inherited from S72
The conditions below are not part of S72.045M, but a patient may have both at the same time. When documentation supports it, S72.045M and the excluded code may both be reported.
Excludes2 — not included here — inherited from S72.0
The conditions below are not part of S72.045M, but a patient may have both at the same time. When documentation supports it, S72.045M and the excluded code may both be reported.
How long has S72.045M existed?
S72.045M 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.
