2027 ICD-10-CM Diagnosis Code S22.39XDFracture of one rib, unspecified side, subsequent encounter for fracture with routine healing
S22.39XD is a billable ICD-10-CM diagnosis code for fracture of one rib, unspecified side, subsequent encounter for fracture with routine healing. The 7th character D means subsequent encounter for fracture with routine healing, used during routine care in the healing or recovery phase. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 559 through 561. The code is exempt from POA reporting. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Fracture of torso, subsequent encounter.

Coding GuidelinesGuidance
The principles of multiple coding of injuries should be followed in coding fractures. Fractures of specified sites are coded individually by site, to the level of detail furnished by medical record content.
A fracture not indicated as open or closed should be coded to closed. A fracture not indicated whether displaced or not displaced should be coded to displaced.
Initial vs. Subsequent Encounter for Fractures
Traumatic fractures are coded using the appropriate 7th character for initial encounter (A, B, C) while the patient is receiving active treatment for the fracture. The appropriate 7th character for initial encounter should also be assigned for a patient who delayed seeking treatment for the fracture or nonunion.
Fractures are coded using the appropriate 7th character for subsequent care for encounters after the patient has completed active treatment of the fracture and is receiving routine care for the fracture during the healing or recovery phase.
Care for complications of surgical treatment for fracture repairs during the healing or recovery phase should be coded with the appropriate complication codes.
Care of complications of fractures, such as malunion and nonunion, should be reported with the appropriate 7th character for subsequent care with nonunion (K, M, N) or subsequent care with malunion (P, Q, R).
The open fracture designations in the assignment of the 7th character for fractures of the forearm, femur and lower leg, including ankle are based on the Gustilo open fracture classification. When the Gustilo classification type is not specified for an open fracture, the 7th character for open fracture type I or II should be assigned (B, E, H, M, Q).

Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
Excludes2
Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.
- burns and corrosions (T20-T32)
- effects of foreign body in bronchus (T17.5)
- effects of foreign body in esophagus (T18.1)
- effects of foreign body in lung (T17.8)
- effects of foreign body in trachea (T17.4)
- frostbite (T33-T34)
- injuries of axilla
- injuries of clavicle
- injuries of scapular region
- injuries of shoulder
- insect bite or sting, venomous (T63.4)
Code First
The underlying condition named in the note is sequenced before this code.
Use Additional Code
Add a second code, after this one, to fully describe the condition.
- code to identify any retained foreign body, if applicable (Z18.-)
Code Also
A second code may be needed to fully describe the condition; the note gives no sequencing direction.
Notes
General instructions on how these codes are used.
- A fracture not indicated as displaced or nondisplaced should be coded to displaced
- A fracture not indicated as open or closed should be coded to closed
- Use secondary code(s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Codes within the T section that include the external cause do not require an additional external cause code
- The chapter uses the S-section for coding different types of injuries related to single body regions and the T-section to cover injuries to unspecified body regions as well as poisoning and certain other consequences of external causes.
7th Character
Every code in the category takes a 7th character from the listed values, with the placeholder X filling any empty positions before it.
- The appropriate 7th character is to be added to each code from category S22
- Ainitial encounter for closed fracture
- Binitial encounter for open fracture
- Dsubsequent encounter for fracture with routine healing this code
- Gsubsequent encounter for fracture with delayed healing
- Ksubsequent encounter for fracture with nonunion
- Ssequela

Questions About S22.39XDOverview
Is S22.39XD (Fracture of one rib, unspecified side) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report fracture of one rib, unspecified side, subsequent encounter for fracture with routine healing on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What does the 7th character D in S22.39XD mean?
The final character D marks a subsequent encounter: use it for routine care while the fracture of one rib, unspecified side is healing, after active treatment has ended. In this category the CMS Tabular List defines D as "subsequent encounter for fracture with routine healing".
What MS-DRG does S22.39XD group to?
When fracture of one rib, unspecified side, subsequent encounter for fracture with routine healing is the principal diagnosis on an inpatient stay, it groups to MS-DRG 559, 561, 560, with relative weights from 0.8258 to 1.8087 depending on complications. Higher weights mean higher Medicare reimbursement.
Is S22.39XD exempt from POA reporting?
Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for fracture of one rib, unspecified side, subsequent encounter for fracture with routine healing on inpatient claims. The code appears in the Injuries to the thorax (S20-S29) range of the CMS exempt list.
Can S22.39XD be reported with S28.1?
Not as a rule. The Excludes1 note at S22, which applies to S22.39XD, lists "transection of thorax (S28.1)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
