Which MS-DRGs does S82.855R group to?

S82.855R sits in MDC 08 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.

  • 564Other Musculoskeletal System and Connective Tissue Diagnoses with MCCmedical
  • 565Other Musculoskeletal System and Connective Tissue Diagnoses with CCmedical
  • 566Other Musculoskeletal System and Connective Tissue Diagnoses without CC/MCCmedical

As a secondary diagnosis, S82.855R is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

Excludes1 — never code together — inherited from S82

The conditions below can never be reported together with S82.855R 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 lower leg (S88.-)

Use additional code — inherited from Chapter 19

Report an additional code alongside S82.855R to fully describe the condition. S82.855R is sequenced first.

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

Excludes2 — not included here — inherited from Chapter 19

  • obstetric trauma (O70-O71)

Excludes2 — not included here — inherited from S80-S89

The conditions below are not part of S82.855R, but a patient may have both at the same time. When documentation supports it, S82.855R and the excluded code may both be reported.

  • burns and corrosions (T20-T32)
  • frostbite (T33-T34)
  • injuries of ankle and foot, except fracture of ankle and malleolus (S90-S99)
  • insect bite or sting, venomous (T63.4)

Excludes2 — not included here — inherited from S82

The conditions below are not part of S82.855R, but a patient may have both at the same time. When documentation supports it, S82.855R and the excluded code may both be reported.

  • fracture of foot, except ankle (S92.-)
  • periprosthetic fracture around internal prosthetic ankle joint (M97.2)
  • periprosthetic fracture around internal prosthetic implant of knee joint (M97.1-)
