Which MS-DRGs does S62.644B group to?
S62.644B 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.
- 562Fracture, Sprain, Strain and Dislocation Except Femur, Hip, Pelvis and Thigh with MCCmedical
- 563Fracture, Sprain, Strain and Dislocation Except Femur, Hip, Pelvis and Thigh without MCCmedical
As a secondary diagnosis, S62.644B is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG. It also carries Hospital-Acquired Condition category 05.

Excludes1 — never code together — inherited from S62
The conditions below can never be reported together with S62.644B 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 wrist and hand (S68.-)
Use additional code — inherited from Chapter 19
Report an additional code alongside S62.644B to fully describe the condition. S62.644B 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 S62.644B, but a patient may have both at the same time. When documentation supports it, S62.644B and the excluded code may both be reported.
Excludes2 — not included here — inherited from S60-S69
The conditions below are not part of S62.644B, but a patient may have both at the same time. When documentation supports it, S62.644B and the excluded code may both be reported.
Excludes2 — not included here — inherited from S62
The conditions below are not part of S62.644B, but a patient may have both at the same time. When documentation supports it, S62.644B and the excluded code may both be reported.
- fracture of distal parts of ulna and radius (S52.-)
Excludes2 — not included here — inherited from S62.6
The conditions below are not part of S62.644B, but a patient may have both at the same time. When documentation supports it, S62.644B and the excluded code may both be reported.
- fracture of thumb (S62.5-)
How long has S62.644B existed?
S62.644B 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.
