Learn about symptoms, diagnostic criteria, periprosthetic joint infection, and revision arthroplasty considerations for accurate PJI diagnosis and reporting. Explore resources for healthcare professionals, including coding best practices and documentation tips for optimal patient care and accurate reimbursement.
Infection in a prosthetic joint, often causing pain, swelling, and impaired function.
Pain, swelling, redness, warmth around the joint, fever, drainage, stiffness, limited range of motion.
Hospital inpatient, outpatient clinic, orthopedic surgery, infectious disease clinic.
ICD-10 Code Families
Complete code families applicable to T84.50
When to use each related code
| Description | When to use |
|---|---|
| Prosthetic Joint Infection | Suspected infection of prosthetic joint. Pain, swelling, fever, or impaired function after joint replacement. |
| Aseptic Loosening | Pain and/or instability in prosthetic joint without signs of infection. Consider mechanical failure of prosthesis. |
| Periprosthetic Fracture | Fracture around a prosthetic joint. Often due to trauma or fall. Sudden pain, swelling and/or deformity. |
Best-practice checklist
- ✓Prosthetic joint infection diagnosis documentation
- ✓ICD-10 code for prosthetic joint infection: T84.5
- ✓Document: Date of infection onset
- ✓Document: Infected joint location
- ✓Document: Causative organism if known
- ✓Document: Clinical findings supporting PJI diagnosis
Common pitfalls to avoid
Coding PJI without identifying the causative organism leads to inaccurate severity and treatment reflection, impacting DRG assignment and reimbursement.
Incorrectly coding sepsis with PJI can lead to overcoding or undercoding, affecting quality reporting and reimbursement. Sepsis must be clinically validated.
Distinguishing between post-operative and chronic PJI is crucial for accurate coding and treatment. Timeframe and clinical presentation must be documented.
Best-practice tips
- 01Document aspiration/tissue culture results for ICD-10-CM T84.5, MS-DRG 544
- 02Specify organism, onset (acute/chronic) for optimal PJI coding, reimbursement
- 03Use standardized PJI diagnostic criteria (e.g., ICM, Musculoskeletal Infection Society) for compliant CDI
- 04Query physician for complete documentation of infection symptoms, lab findings for HCC capture
- 05Regularly audit PJI documentation for coding accuracy, compliance, and revenue integrity

Ready-to-paste narrative
Patient presents with signs and symptoms suggestive of prosthetic joint infection (PJI) of the [Specify joint: e.g., right knee]. Onset of symptoms began approximately [Timeframe] ago and include [List symptoms: e.g., increasing pain, swelling, erythema, warmth, decreased range of motion, fever, chills]. Patient reports [Pertinent history related to the prosthetic joint: e.g., date of original arthroplasty, prior revisions, recent trauma, previous infections]. Physical examination reveals [Specific findings: e.g., tenderness to palpation around the prosthesis, joint effusion, limited mobility, sinus tract formation]. Laboratory studies ordered include erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and joint aspiration for synovial fluid analysis and culture. Differential diagnosis includes aseptic loosening, periprosthetic fracture, crystalline arthropathy, and bursitis. Pre-operative antibiotics initiated with [Antibiotic name and dosage]. The patient's clinical presentation, laboratory markers, and risk factors are concerning for prosthetic joint infection. Surgical intervention, such as debridement, antibiotics, and implant retention (DAIR), one-stage revision, or two-stage revision arthroplasty, is being considered and discussed with the patient. Risks and benefits of each procedure were explained. Patient will return for follow-up and further evaluation in [Timeframe]. ICD-10 code T84.5- [Specify laterality and site] is considered, pending culture results and definitive diagnosis. CPT codes for procedures performed will be documented upon completion of surgical intervention. Plan to consult with infectious disease specialist for further management recommendations. Continued monitoring of inflammatory markers and clinical response to treatment will be performed.
