Clinical Context: Sensory vs. Painful Phantom Limb
Code Classification
ICD‑10‑CM Diagnosis Code — wRVU, assistant payable, and global period do not apply.
🔍 Code Description
ICD‑10‑CM G54.7 classifies phantom limb syndrome without pain, a sensory phenomenon occurring after limb amputation.
Patients perceive the presence, movement, or position of the missing limb without associated pain.
This condition reflects cortical remapping, peripheral nerve changes, and altered proprioceptive pathways. It is distinct from painful phantom limb syndrome and must be coded separately.

Sensory vs. Pain Phenotype
Use G54.7 only when no pain is documented. If the provider documents “phantom sensations,” always confirm whether pain is present.

- Sensory phantom phenomena
- Perceived limb movement without pain

| G54.6 | Phantom limb syndrome with pain | Painful variant; cannot be coded together |
| T87.89 | Other complications of amputation stump | Use when stump pathology explains symptoms |
Excludes 1 Violation Risk

| F45.42 | Psychological factors associated with pain | May be coded if documented; not billable so not wikilinked |
📋 Clinical Overview
Sensory vs. Painful Phantom Limb Syndromes
This table distinguishes non-painful sensory phenomena from painful phantom limb and chronic pain syndromes.
| Feature | G54.7 — Non-Painful | G54.6 — Painful | G89.21 — Chronic pain due to trauma |
|---|---|---|---|
| Pain present | No | Yes | Yes |
| Sensory phenomena | Tingling, pressure, movement | Burning, stabbing, electric | Variable |
| Etiology | Cortical remapping | Neuropathic + central sensitization | Chronic pain mechanisms |
Documentation Tip — Confirm Pain Status
If documentation states “phantom sensations,” query to determine whether pain is present.
Manifestations & Symptom Burden
- Proprioceptive sensations: perceived limb position
- Movement illusions: feeling the limb move
- Pressure or tingling: non-painful sensory input
- Functional impact: may affect prosthetic training
Coding Manifestations
Always code associated symptoms when documented:
- G47.00 — Insomnia
- F32.A — Depression
- M79.2 — Neuralgia (if unrelated to phantom limb)

🏥 MS-DRG Assignment
MDC 01 — Diseases & Disorders of the Nervous System
| DRG | Title | Est. Relative Weight* |
|---|---|---|
| 073 | Cranial & peripheral nerve disorders with MCC | ~1.3-1.6 |
| 074 | Cranial & peripheral nerve disorders without MCC | ~0.8-1.0 |
Approximate — verify against FY2026 IPPS tables.
Sequencing
G54.7 may be principal when the admission is for evaluation of phantom sensations. Secondary MCC/CCs determine DRG 073 vs. 074.

🛠️ Commonly Associated CPT Codes (Neurology / PM&R)
Outpatient & Profee Context
These CPT codes are commonly associated with evaluation or treatment of phantom limb phenomena.
| CPT Code | Description | Profee Notes |
|---|---|---|
| 97110 | Therapeutic exercises | Used in prosthetic training |
| 97112 | Neuromuscular reeducation | Sensory retraining |
| 97761 | Prosthetic training | Requires documentation of functional goals |

NCCI Bundling Considerations
- E/M + therapy services → Modifier ‑25 required
- Multiple therapy modalities → Modifier ‑59 when distinct

💊 Coding Scenarios and Examples
Scenario 1 — Outpatient: Non-Painful Phantom Sensations
Clinical Vignette: A 62‑year‑old man with a right above‑knee amputation reports tingling and movement sensations in the missing limb. No pain is reported.
Principal Diagnosis:
- G54.7 — Phantom limb syndrome without pain
Secondary Diagnoses:
- F32.A — Depression (documented mood symptoms)
Scenario 2 — Inpatient: Prosthetic Training Interference
Clinical Vignette: A 55‑year‑old woman is admitted for prosthetic gait training. She reports non-painful phantom sensations interfering with balance.
Principal Diagnosis:
- G54.7 — Reason for admission
Secondary Diagnoses:
MS‑DRG:
Groups to DRG 074 unless MCC present.
Scenario 3 — CDI Query: “Phantom Sensations”
Clinical Vignette: Provider documents “phantom sensations,” but does not specify whether pain is present.
Action / Outcome:
Query provider: “Are the phantom sensations painful or non-painful?”
Query Response:
Provider adds: “Patient reports non-painful tingling sensations.”
Corrected ICD-10-CM Coding:
- G54.7 — Phantom limb syndrome without pain
⚠️ Coding Pitfalls and Tips
| Pitfall or Tip | |
|---|---|
| ❌ | Coding pain when none is documented. Do not use G54.6 unless pain is explicitly stated. |
| ❌ | Using stump complication codes incorrectly. Use T87.89 only when stump pathology is present. |
| ✅ | Query for pain status. “Phantom sensations” alone is insufficient. |
| ✅ | Capture comorbidities. Influences DRG grouping. |
| ✅ | Document functional impact. Supports therapy and prosthetic training services. |
