ICD-10 code S43.014D: Right shoulder dislocation, subsequent encounter

Key takeaways

S43.014D is a billable ICD-10-CM code for anterior dislocation of the right humerus at a subsequent encounter

The 7th character D means the patient is receiving routine care after active treatment has ended, not a new or emergency visit

The 6th character 4 carries severity and side together, so a right-sided anterior subluxation takes S43.011D instead

Common coding error: using S43.014A for follow-up physical therapy visits when S43.014D is correct

Practice management software like Pabau helps practices submit S43.014D with accurate encounter documentation

ICD-10 code S43.014D describes an anterior dislocation of the right humerus at a subsequent encounter. Coders in orthopedic, sports medicine, and physical therapy settings reach for it at follow-up visits, once active treatment for the injury has concluded.

The code sits in the glenohumeral (shoulder joint) block of S43. It covers the humeral head leaving the glenoid, not an injury to either collarbone joint.

S43.014D is valid for the current fiscal year. It appears in the ICD-10-CM tabular list under Chapter 19 (S00-T88: Injury, poisoning, and certain other consequences of external causes). It is a terminal, billable code, so no further character specificity is required or possible.

The CDC/NCHS ICD-10-CM web tool confirms its status as a fully billable diagnosis code accepted across US claim types.

Understanding the S43 ICD-10-CM category

The S43 parent category covers dislocations and sprains of the joints and ligaments of the shoulder girdle. That means the glenohumeral joint, the acromioclavicular (AC) joint, and the sternoclavicular joint. Together, these three articulations give the arm its full range of motion.

Anterior glenohumeral dislocations account for roughly 95% of all shoulder dislocations seen in emergency and urgent care settings. That is why the S43.01 code family sees high claim volume in orthopedic billing. Practitioners in sports medicine practices see this injury regularly, especially in active adults and athletes.

Within S43, the 4th character picks the joint. The 5th character then narrows the injury, and the 6th records severity and side in a single digit. S43.014D sits at the end of that chain: shoulder joint, anterior direction, complete dislocation of the right humerus, subsequent encounter.

One point trips up coders who move between shoulder codes. The grading scheme changes with the joint. Glenohumeral codes in S43.0 are split by the direction the humeral head travels. Acromioclavicular codes in S43.1 are split by how far the joint has displaced.

• S43.0xx: Subluxation and dislocation of shoulder joint (glenohumeral), the block containing S43.014D
• S43.01x: Anterior subluxation and dislocation of humerus, the sub-block containing S43.014D
• S43.02x: Posterior subluxation and dislocation of humerus
• S43.03x: Inferior subluxation and dislocation of humerus
• S43.1xx: Subluxation and dislocation of acromioclavicular joint, graded by percentage of displacement rather than direction
• S43.2xx: Subluxation and dislocation of sternoclavicular joint
• S43.4xx-S43.9xx: Sprains of shoulder girdle joints and ligaments

Breaking the code down, character by character

Every character in S43.014D carries clinical meaning. Misreading even one character leads to a wrong code and a likely claim denial. Here is what each position encodes:

The 6th character is where this family departs from most of ICD-10-CM. It encodes severity and side in one digit instead of giving laterality its own position.

A right-sided anterior subluxation is therefore S43.011D, while a right-sided anterior dislocation is S43.014D. Coders who expect 1 to mean right in every code will land on the subluxation code out of habit.

The digit 9 never means unspecified side here. An anterior dislocation with no documented side is S43.016D, and S43.019D does not exist. Note the wording of the official descriptor too. It says humerus, not glenohumeral joint, so searching a code lookup for glenohumeral will not surface S43.014D.

What “subsequent encounter” means in practice

The 7th character D is where the most billing errors occur. Subsequent encounter describes the phase of care, not the visit number. It applies once the patient has finished active treatment and moved into routine care during healing.

Per ICD-10-CM Official Guidelines Section I.C.19.a, subsequent encounter (D) is appropriate when the patient is receiving routine aftercare for a healing condition. Active treatment (A) applies only when a provider is managing the injury for the first time. It also applies when a provider makes a meaningful change to the treatment plan.

Physical therapy visits, sling checks, range-of-motion monitoring, and rehabilitation sessions after the acute phase are all subsequent encounters. The same logic runs through Chapter 19. A humerus fracture code such as S42.212D takes D for exactly the same reason.

S43.014A, S43.014D, and S43.014S: When to use each

Sequela (S) requires a separate condition code listed first, with S43.014S following as the cause. Practices sometimes reach for S when D is the right choice. It happens most often when a patient returns months later with residual stiffness still tied to the original dislocation.

Clinical description: Anterior dislocation of the right shoulder

The glenohumeral joint is a ball-and-socket joint where the humeral head articulates with the glenoid fossa of the scapula. Its shallow socket provides excellent mobility but comparatively little intrinsic stability. That is why it dislocates more often than any other joint in the human body.

Anterior dislocation is by far the most common type. The humeral head displaces anteriorly and inferiorly, typically when the arm is abducted and externally rotated at the moment of impact.

Common mechanisms include a fall onto an outstretched hand or a direct blow to the back of the shoulder. Forced external rotation beyond the joint’s range is another common cause.

• Presentation: Flattened deltoid contour, arm held in slight abduction and external rotation, palpable absence of the humeral head beneath the acromion
• Confirmation: Anteroposterior and axillary or Y-view shoulder radiograph confirming anterior humeral head position
• Active treatment: Closed reduction under sedation or procedural anesthesia, followed by immobilization
• Subsequent care: Progressive sling weaning, physical therapy for rotator cuff strengthening and proprioception, monitoring for recurrence

Practices that see shoulder dislocation patients through the full care continuum need clean documentation at every stage. That runs from the initial reduction through rehabilitation, where tests like the lift off test track rotator cuff recovery. A range of motion assessment at each visit documents the progress that justifies the D character.

Physical therapy practices carry most of that subsequent encounter volume. Their visit templates need to separate active treatment from routine care in the record. A standard SOAP note structure handles that if the assessment line names the phase of care.

Documentation phrases that map to S43.014D

Clinicians rarely write the tabular descriptor word for word. The table below maps the phrasing that shows up in shoulder notes to the code it supports. Each row assumes the encounter phase is documented as routine follow-up care.

That last row is the most frequent mix-up in shoulder coding. An acromioclavicular separation is not a glenohumeral dislocation, and the two are graded on different axes.

S43.131D means dislocation of the right AC joint with greater than 200% displacement, subsequent encounter. That is a grade V separation, and it has nothing to do with the humeral head.

Sibling and related codes for shoulder dislocation

Coders billing shoulder dislocations need to know the codes that surround S43.014D. The AAPC Codify ICD-10-CM lookup lets you search the full S43 range for adjacent codes. The sprain codes lower in the category, such as S43.491S, take the same three 7th characters.

Run the selected code through a current-year lookup before submission to confirm it is still active.

Coding guidelines and compliance for subsequent encounter claims

The CMS ICD-10-CM coding guidelines govern how Chapter 19 codes are assigned. For subsequent encounter coding, Section I.C.19 provides the authoritative framework. Three compliance points matter most for claims involving S43.014D.

• Subsequent encounter requires completed active treatment: The code applies only after active treatment has concluded. That can be by the original treating provider, or by another provider continuing the plan without substantive changes. A second opinion visit that produces a new treatment plan reverts to the initial encounter code.
• Direction of dislocation must be documented: The record needs anterior dislocation, anterior glenohumeral dislocation, or equivalent wording to support the 5th character 1. Shoulder dislocation NOS routes to S43.004D instead.
• Severity and side must both be documented: The 6th character 4 needs the record to state a complete dislocation of the right shoulder. A documented anterior subluxation of the right humerus is S43.011D, and an undocumented side is S43.016D.

Practices should build documentation templates that capture all three elements as structured fields. With direction, severity and side, and encounter phase in the note, coders have what they need without chasing providers for addenda.

Outcome measures belong in the same template. A score from the Global Rating of Change scale shows the visit was routine progress monitoring rather than a new acute event. A shoulder range of motion chart does the same job for mobility.

Common coding errors to avoid

These are the mistakes that show up most often in orthopedic and sports medicine billing audits for this code family:

• Using S43.014A at every visit: Some practices default to the initial encounter code throughout treatment. That is incorrect, and it creates a claim pattern payers flag as inconsistent with typical care timelines.
• Picking S43.011D by digit habit: In most ICD-10-CM codes, 1 in the laterality position means right. Here, 1 means anterior subluxation of the right humerus, and a complete right-sided dislocation is 4.
• Coding an AC separation in the glenohumeral block: A record that says AC joint separation belongs in S43.1, graded by displacement. Grades III through V never support S43.014D.
• Confusing D with S for chronic instability: A patient returning months later with recurrent dislocation needs a judgment call. If the instability is a sequela, use S43.014S with the instability code first. If it is a new acute dislocation, start again at S43.014A.
• Incorrect sequencing with sequela codes: When S43.014S applies, the sequela condition such as chronic shoulder instability is sequenced first. S43.014S is the causal code and follows the manifestation code.

Practices managing high volumes of musculoskeletal claims can reduce these errors with clean patient record documentation workflows. A structured workflow ties the encounter type to the visit note automatically, rather than leaving coders to interpret unstructured notes.

Documentation requirements for billing S43.014D

Claims for S43.014D rest on specific documentation elements. Missing any one of them creates the conditions for a denial, an audit flag, or a payer request for additional documentation.

Practices using integrated claims management software can link documentation fields directly to the coding workflow. That narrows the distance between what the clinician writes and what the coder can defend at audit. It matters most in busy rehabilitation practices, where one dislocation generates a run of subsequent encounter claims.

How Pabau supports orthopedic and physical therapy coding workflows

Practices billing S43.014D regularly deal with the same documentation problem at scale. A patient referred from an emergency department reduction into a six-week rehabilitation program generates six or more subsequent encounter claims. Each one needs consistent documentation of the joint, the direction, the side, and the encounter phase.

Pabau addresses this at the note level. You build a structured template that captures each of those four elements as its own field. The coder never has to interpret free text.

From there, the coded encounter moves into the claim without manual re-entry. That removes the retyping step where the wrong 7th character usually slips in.

The outcome is fewer addendum requests, cleaner submissions, and a defensible audit trail when payers review your shoulder dislocation claim patterns. Many practices fold that review into their HIPAA compliance checks. Standardizing documentation usually resolves most of what auditors flag on Chapter 19 injury claims.

Conclusion

S43.014D covers a high-volume clinical scenario that touches emergency departments, orthopedic groups, and physical therapy practices alike. Two decisions carry most of the denial risk on it.

One is the 7th character, which separates active treatment from routine follow-up care. The other is the 6th character, which folds severity and side into a single digit that is easy to misread. Get both into the note as structured fields and the code stops being a judgment call.
