M54.14 identifies radiculopathy localized to the thoracic spine — nerve root dysfunction in the mid-to-upper back producing pain, sensory changes, or motor deficits in a thoracic dermatomal distribution.

Documentation tips

What should appear in the chart to support M54.14.

• Specify the thoracic region explicitly — document the affected spinal level (e.g., T6-T7) when known, as it strengthens medical necessity and differentiates from thoracolumbar (M54.15) involvement.
• Record dermatomal findings by name: band-like chest wall pain, intercostal numbness, or paresthesia tracking a specific thoracic dermatome — 'mid-back pain' alone does not support M54.14.
• Document the results of neurological exam components — reflexes, sensation testing, motor strength — to establish nerve root dysfunction rather than referred pain.
• If MRI or CT myelogram is obtained, note whether disc herniation or spondylosis is absent; the presence of either shifts the code to M51.14 or M47.2-.
• When conservative care has been attempted, document the type and duration (e.g., PT, NSAIDs, activity modification) to support medical necessity for interventional CPT services like epidural steroid injection (62321).

Common coding pitfalls

The recurring mistakes coders make with M54.14 and adjacent codes.

Source · Editorial brief grounded in CDC ICD-10-CM tabular guidance, AAOS coding references, and cited references ↓

• Reporting M54.14 alongside M51.14 or M47.2- violates the Excludes1 note under M54.1 — when disc disorder or spondylosis is confirmed as the cause, M54.14 is excluded entirely; use the more specific causal code instead.
• Confusing thoracic (M54.14) with thoracolumbar (M54.15) — the thoracolumbar code applies to the T12-L1 junction region; document the exact spinal level to avoid miscoding the transition zone.
• Defaulting to M54.14 when the provider only documents 'thoracic back pain' — thoracic spine pain without nerve root findings codes to M54.6, not M54.14; radiculopathy requires documented neurological involvement.
• Using M54.14 when the ESI is performed at T12-L1 — that junction maps to thoracolumbar (M54.15) or lumbar (M54.16) depending on the documented level and the provider's stated diagnosis; align the diagnosis code to the documented spinal region, not the needle entry point.
