What This Code Means

Other nerve system complications following a shingles infection that are not specifically categorized elsewhere.

Coding Tips

•Use this code only when the postherpetic nervous system complication does not fit B02.21, B02.22, or B02.24
•Clearly document the specific neurological complication in the medical record

Clinical Significance

This code captures postherpetic nervous system complications not classified under the more specific codes (geniculate ganglionitis, trigeminal neuralgia, polyneuropathy, or myelitis). Examples include postherpetic cranial nerve palsies other than facial nerve, autonomic neuropathy, or encephalitis occurring as a late complication of shingles.

Documentation Requirements

✓Documented history of herpes zoster with timeline to current symptoms
✓Specific neurological complication described that does not fit B02.21-B02.24
✓Clinical examination documenting the nervous system involvement
✓Reasoning for why more specific postherpetic codes do not apply
✓Treatment plan for the specific neurological complication

Commonly Confused Codes

B02.21-B02.24 — More specific postherpetic nervous system codes; use B02.29 only when the complication does not fit any of these G53 (Cranial nerve disorders in diseases classified elsewhere) — May be used as an additional code to specify which cranial nerve is affected B02.0 (Zoster encephalitis) — If the complication is postherpetic encephalitis, B02.0 may be more appropriate
